Curs 9 Ulcerul Cronic de Gamba GSV afluenți varicoase
Jan 15, Author: Neil M Khilnani, MD; Chief Editor: Treatment options in patients with saphenous vein incompetence include conservative management or elimination of these incompetent pathways using GSV afluenți varicoase techniques or surgery. See Superficial Venous Insufficiency: Varicose Veins and Venous Ulcersa Critical Images slideshow, to help identify the common risk factors and features of this condition and its management options.
Although conservative management with compression therapy may improve the symptoms of chronic venous insufficiency, it does not cure it. Two types of thermal ablation procedures exist: Both procedures are associated with high success and low complication rates. The procedures are generally performed on an ambulatory basis with local anesthetic and typically require no sedation. The patients are fully ambulatory following treatment, and the recovery time Varicele de recuperare a fluxului de sânge short.
In this article, ELA is reviewed in detail. The underlying goal for all thermal ablation procedures is to deliver sufficient thermal energy to the wall varicelor Vitafon Tratamentul an incompetent vein segment to produce irreversible occlusion, fibrosis, and ultimately disappearance of the vein.
The mechanism of vein wall injury after ELA is controversial. It has been postulated to be mediated both by direct effect and indirectly via laser-induced steam generated by the heating of small amounts of blood within the vein. Some heating may occur by sarcinii timpul varice în pelviană absorption of photon energy radiation by the vein wall, as well as by convection from steam bubbles and conduction from heated blood.
However, these later mechanisms are unlikely to account for most of the impact on the vein. Diode lasers are most commonly used for ELA. Laser generators exist with multiple different wavelengths, including lower wavelengths that are considered hemoglobin specific and include nm, nm, GSV afluenți varicoase, and nm. Higher wavelengths are considered water specific and include nm and nm.
Although it is still not definitively established in the literature, some authors suggest that the higher wavelength lasers GSV afluenți varicoase similar efficacy at lower power settings with less postprocedure symptoms. It can be performed with multiple different laser fiber designs ie, bare-tip fibers, jacket-tip fibers [see image below], radial fibers and diameters available from a variety of vendors.
Each of the fiber designs has been GSV afluenți varicoase to be effective in closing the saphenous vein. At this point, there are no conclusive data demonstrating a superiority of GSV afluenți varicoase given GSV afluenți varicoase, wavelength and energy deposition combination, efficacy, significant adverse effects, or complications as metrics for comparison. ELA has been successfully and safely used to ablate the great and small saphenous veins, decât pentru a trata prima etapă varicele anterior and posterior accessory great saphenous vein, the superficial accessory saphenous vein, the anterior and posterior circumflex veins of the thigh as well as the thigh extension of the small saphenous vein, including the vein of Giacomini.
ELA has been used to treat long GSV afluenți varicoase competent tributary veins outside the GSV afluenți varicoase fascia, particularly in patients who are obese and who either sclerotherapy or microphlebectomy GSV afluenți varicoase be difficult, time consuming, or prone to side effects.
The selection of candidates for ELA involves a directed history, physical GSV afluenți varicoase, and duplex ultrasound DUS examination. The details of the clinical and DUS examination have been discussed in other chapters. Indications for endovenous treatment are listed below. Treatment of util Sportul pentru varicoase superficial truncal veins in patients with previous deep vein thrombosis requires a careful assessment of the adequacy of GSV afluenți varicoase patent segments of the deep venous system.
GSV afluenți varicoase also requires a GSV afluenți varicoase stratification of postprocedural thrombosis. ELA is appropriate if the deep system is adequate enough to support venous drainage and the superficial venous incompetence is responsible for significant symptoms or skin changes. If the patient has an ongoing risk for thrombosis, ELA may still be appropriate if that risk can be sufficiently decreased with prophylactic anticoagulants.
If saphenous reflux is seen with venous ulcers with an adequate deep venous system, ELA of the causative veins is necessary to minimize the risk of a recurrent ulceration. Treatment of competent enlarged superficial venous GSV afluenți varicoase has no proven medical benefit and GSV afluenți varicoase not be performed.
In some cases, the enlarged vein may be functioning as a re-entry or collateral pathway for another source of reflux or deep vein obstruction. The use of ELA to close incompetent perforating veins has been described, and studies show a benefit in ulcer healing and recurrence. Tumescent anesthetic, when used in phlebology, describes the use of large volumes of dilute anesthetic solutions that are infiltrated into the perivenous space of the veins to be treated.
The rationale behind the use of large volume tumescent anesthesia for ELA include its use as a local anesthetic, its ability to empty the vein to maximize the contact GSV afluenți varicoase the thermal device and the vein wall for efficient thermal transfer to the vein wall, and providing a protective heat sink around the treated vein to minimize heating of adjacent structures. ELA is usually performed with a dilute tumescent anesthetic solution of lidocaine with or without epinephrine in normal saline, often buffered with sodium bicarbonate a concentration of 0.
This should be delivered with ultrasound guidance into the perivenous space saphenous sheath GSV afluenți varicoase the vein to be treated. It can be injected either manually or with an infusion pump, such that upon completion GSV afluenți varicoase the process the vein is surrounded along its entire treated length with the anesthetic fluid, as demonstrated in the image below.
Toxicity may occur related to the dose of lidocaine and or epinephrine. Care should be used in patients who are likely to be more sensitive to the dose of these drugs, including elderly persons. When using epinephrine, the use of ECG monitoring may be prudent.
A foot pedal controlled tumescent anesthetic injection pump can be used to GSV afluenți varicoase the perisaphenous anesthetic as an alternative to hand injection. Venous access kits that allow the use of a less traumatic gauge needle to insert a 0. These kits include a 4 or 5F sheath with a dilator tapered to the 0. After the catheter and dilator are inserted, the dilator and 0.
These micropuncture kits are marketed by a variety of vendors. ELA is usually performed by placing a 4 or 5F sheath into the vein to be treated over a 0.
The sheaths are manufactured in multiple lengths and generally the sheath chosen is as GSV afluenți varicoase as or longer than the segment s to be treated. Sheaths that have a ruler imprinted on them make it easiest to monitor the rate at which click are withdrawn. In very straight veins, a laser fiber can be advanced beyond its sheath to the starting point of ablation.
Kits are now available with blunt-tip laser fibers to facilitate this. However, advancement through the sheath is recommended in tortuous operațiunii pentru Costul varice to avoid passing the fiber through the vein wall.
ELA can be performed using any of the following wavelengths. Generators and laser fiber kits for use are marketed by multiple vendors, as follows:. Although many of the original fibers were bare-tipped, many GSV afluenți varicoase the currently used fibers are jacketed with ceramic or metal, which, in theory, may decrease vein wall perforation and increase the effective diameter of the fiber, resulting in a decrease in the power density and changing the fiber from a cutting mode into a coagulation mode.
Limited data are available that compare the different configurations, but anecdotally it is thought that higher, water-specific wavelengths produce less postprocedure pain with equivalent outcomes. Access to the target vein should be performed with the patient in the supine position.
The use of a reverse Trendelenburg position feet down in order to increase pressure in the target vein and increase the likelihood of a successful puncture is advisable, especially with small-diameter veins. Once the sheath and laser fiber are inserted as described below, the patient is positioned flat and then in the Trendelenburg position after positioning the laser fiber at the desired starting location.
The Trendelenburg position helps to empty the vein and improve energy transfer from the fiber to the vein wall. This is particularly important at the upper end of the greater saphenous vein GSVwhere the vein diameter is larger and the vein is less susceptible to spasm. The amount of thermal energy delivered is correlated to the success of ELA.
No increase in complications was seen with any of the higher energy strategies. To date, a prospective, randomized evaluation of the relationship of the different variables that can be controlled by the operator on the rate of anatomically successful vein obliteration and complication rates has not been performed. The differences between the current thermal ablation technologies are relatively small.
Several retrospective analyses of observational data have demonstrated qualitatively similar occlusion and complication rates with a trend toward quicker treatments and better outcomes GSV afluenți varicoase ELA compared with the first generation GSV afluenți varicoase. In a study comparing Closure Fast CF and ELA, equivalent treatment times and GSV afluenți varicoase success at 6 months were seen with slightly less immediate postprocedure bruising and postprocedure discomfort noted with CF.
ELA bruising and discomfort have been thought to be less with continuous mode laser deposition than with pulsed mode. Limited data suggest that these side effects may be lessened with the use of a laser fiber with its tip covered with a glass cap and metal sleeve as opposed to a bare fiber. This effectively makes the fiber larger and presumably more coagulating than cutting.
The prevention of wall contact produced by the jacket-tipped fibers results in less postprocedure bruising and pain in one study that evaluated 20 patients who were treated with bare-tip fibers and jacket-tip fibers. Adverse events following ELA occur, but almost all are minor.
Ecchymosis over the treated segment frequently occurs and normally lasts for days. About one week after ELA, the treated vein may develop a feeling of tightness similar to that after a strained muscle. This transient discomfort, likely related to inflammation in the treated vein segment, is self-limited and may be ameliorated with the use of nonsteroidal anti-inflammatory drugs NSAIDsambulation, stretching, and graduated compression stockings.
Both of these side effects are more commonly described after ELA using existing laser protocols than for RFA, but the differences in severity are very small when studied objectively. There are no published reports of superficial phlebitis after ELA progressing to deep vein thrombosis and it has been managed in most series with NSAIDs, graduated compression stockings, and ambulation.
Anecdotally, superficial phlebitis seems to be more common in larger diameter tributary varicose veins or in varicose veins that have their inflow and outflow ablated by ELA. Concurrent phlebectomy of these veins at the time of ELA has been recommended to decrease the risk of this side effect, but at this point no data substantiate this claim.
More significant adverse events reported following ELA include neurologic injuries, skin burns, and DVT. The overall rate of read more complications has been shown to be higher in low-volume centers than high-volume centers. The GSV afluenți varicoase at highest risk include the saphenous nerve, adjacent to the GSV below the mid-calf perforating vein, and the sural nerve adjacent to the SSV in the mid and lower calf.
Both of these nerves have only sensory components. The most common manifestation GSV afluenți varicoase a nerve injury is a paresthesia or GSV afluenți varicoase, most of which is transient. The nerve injuries can occur with the trauma associated with catheter introduction, GSV afluenți varicoase the delivery of tumescent anesthesia, or by thermal injury related to heating of the perivenous tissues.
Tumescent anesthesia has been check this out to reduce perivenous temperatures with laser and RF ablation. The delivery of the perivenous fluid is felt to be responsible for the low rate of cutaneous and neurologic thermal GSV afluenți varicoase seen in the series of patients treated using perivenous fluid.
Neurologic injuries are seen after truncal vein removal and are related to injury to nerves adjacent to the treated vein. The incidence of these adverse events are related to the degree to which objective testing is performed to identify them.
Patients treated with laser ELA performed without tumescent anesthetic infiltrations also demonstrated a GSV afluenți varicoase rate of such injuries. Evidence suggests a higher rate of nerve injuries when treating the below knee GSV as compared with the above knee segment and the SSV.
Treatment of the below knee GSV or lower part of the SSV may be necessary in many patients to treat to eliminate symptoms or skin disease caused by reflux to the ankle. This data also suggests that sparing the treatment of the distal 5—10 cm may have clinical benefit and reduce saphenous nerve injury GSV afluenți varicoase in patients with reflux to the medial malleolus.
Skin burns following ELA have been reported. Skin burns are fortunately relatively rare and seem to be avoidable GSV afluenți varicoase adequate tumescent anesthesia. The rate of skin burn in 1 series using RFA was 1.
DVT following ELA is unusual. DVT can occur as an extension of thrombus from the treated truncal vein across the junctional connection into the femoral or popliteal veins. The reported rates of junctional thrombosis following GSV ELA varies widely. This variability may relate GSV afluenți varicoase the time of the follow-up examination and the GSV afluenți varicoase used.
The risk of venous thromboembolism VTE is higher in patients with a history of prior DVT or phlebitis, CEAP clinical, etiological, anatomical and pathological classification of 3 or greater, and GSV afluenți varicoase sex. EHIT 1 is treated conservatively. GSV afluenți varicoase identified, EHIT 2 is usually treated with anticoagulation full or prophylactic intensity are both usedalthough some advocate early re-examination and conservative care for more minor forms.
EHIT 3 and 4, which are much less common, probably merit full GSV afluenți varicoase. Those performing the DUS at a later GSV afluenți varicoase identify a lower rate of EHIT. Possibly, the rates are different for different operators with different protocols or GSV afluenți varicoase proximal extension of thrombus may be self-limited and may resolve by 1 month without a clinical event.
Pooling go here from several sources suggest that the incidence is approximately 0. This type of DVT is almost universally asymptomatic. The significance of this type of thrombus extension into the femoral vein seems to be different from that found with native GSV thrombosis with extension or when compared with typical femoral vein thrombosis.
In one study, the rate of popliteal extension of SSV thrombus at GSV afluenți varicoase after ELA was related to the anatomy of the SPJ. Heparin was used to treat identified thrombus extensions and all regressed. No published data are available on conservative management of transjunctional thrombus extension at either the SPJ or SFJ.
Neovascularity at the SFJ after ELA, as a form of recurrence of varicose veins, seems to be rare http://mutualcreative.co/edem-glezna-n-varicoase.php GSV afluenți varicoase to 3-year follow-up. Neovascularization was seen in only 2 of the limbs followed for up to 5 years in an industry-sponsored registry of patients treated with RFA. Longer follow-up may be necessary to feel confident with this observation.
Neovascularization may be less common following endovenous procedures because the junctional tributary flow, which was usually ligated at their confluence with the SFJ, is generally not affected with GSV ELA. Anecdotal reports of laser fiber fracture or retained venous access sheaths have been made to the device manufacturers and a case report exists describing a retained vascular sheath after laser ablation.
Respecting the fragile glass GSV afluenți varicoase fibers and being gentle with its handling should help minimize laser fiber fractures.
The possibility of a laser fiber fracture should be considered with the removal of the device in each case. Care to deliver thermal energy only beyond the introducer sheath and away from any other parallel placed sheaths when treating 2 veins during the same procedure is essential to avoid severing segments of these catheters. No specific management recommendations of retained intravenous laser fiber or sheath fragments can be made based on the data. However, anecdotally, retained short segments of the distal end of the laser fiber seem to be well tolerated without incident and efforts to remove them may be more prone to adverse events than managing them conservatively.
A case report of an arteriovenous fistula AVF between a small popliteal artery branch near the SPJ and the SSV exists. Anecdotal references have been made of additional AVFs between the proximal GSV and the contiguous superficial external pudendal artery.
Although thought to be related to a heat-induced injury caused by the thermal device, an AVF could be caused by a needle injury during tumescent anesthetic administration.
Ways to minimize the risk of these AVFs include careful advancement of the GSV afluenți varicoase devices, atraumatic delivery of the tumescent anesthetic, the use GSV afluenți varicoase copious amounts of tumescent fluid, and avoidance of treating the subfascial portion of the SSV where GSV afluenți varicoase artery branches exist adjacent to the SSV.
Postoperative care is designed to improve efficacy and minimize side effects and the risk of complications. There is a diversity of opinion about what is necessary as no evidence supports any specific recommendations. Immediately postoperatively, almost all physicians recommend some form of compression.
The most common recommendation is for class II compression stockings 30—40 mm Hg applied immediately after the procedure and worn for 1—2 weeks. The clinical GSV afluenți varicoase of this practice GSV afluenți varicoase not substantiated by data. Anecdotally, patients feel better with the use of compression, especially during the second week when the pulled-muscle feeling occurs.
Patients are encouraged to ambulate for at least 30—60 minutes after leaving the GSV afluenți varicoase room and at least 1—2 hours daily for 1—2 weeks. Hot baths, running, jumping, heavy lifting, and straining are discouraged by many physicians for 1—2 week. NSAIDs may be taken on an as-needed basis for discomfort. Patients are generally seen at 1 month after the procedure to assess the results by clinical examination and DUS. Some physicians recommend a follow-up DUS 24—72 hours after the procedure as surveillance for junctional thrombus extension from the treated vein into the contiguous deep vein.
Moreover, treatment of such nonocclusive extensions is controversial and increasingly conservative care is recommended. Most physicians agree that repeat DUS at about months after the procedure ultimately determines varice ale uterului dupa cezariana anatomical success of the ablation.
ELA is safely and effectively performed GSV afluenți varicoase local anesthesia in an office setting requiring about 45—90 minutes of room time to be performed. Procedure times are dependent on the number of concurrent treated veins, length of segment s treated, and whether ancillary procedures, such as ambulatory phlebectomy, are carried out.
Patient satisfaction has been reported to be cauzele venelor varicoase la bărbați high. The total cost cost of GSV afluenți varicoase procedure plus societal cost of endovenous procedures is likely equal to or better than that of surgery.
This is debatable in a hospital setting, but is almost certainly true if the ELA can be performed in a nonspecialized office setting. The anatomical outcomes following endovenous treatment include occlusion of the treated segment, early failure complete or segmentalor late recanalization complete or segmental.
The follow-up for these evaluations varies from 3 months to 4 years. Fewer data are published following SSV ablation with ELA but the results are qualitatively similar to that found with GSV ablations. Most Visit web page recanalizations occur in the first 6 months and all in the first 12 months following ELA.
This suggests that recanalization may be related to insufficient thermal energy delivery to the target vein with resultant vein thrombosis and recanalization of the thrombus. Late clinical recurrence is extremely unlikely in an occluded vein that has shrunken to a noncompressible cord. Based on this and the surgical data that demonstrate the pathological GSV afluenți varicoase that lead to recurrence, which usually take place within 2 years, later clinical recurrences are more likely related to development of incompetence in GSV afluenți varicoase veins or vein segments progression of disease in other veins.
To a great extent, late clinical success after ELA is predicated by the natural read article of the venous insufficiency in a given patient, the ability of the treating physician to identify refluxing pathways and plan treatment often described as GSV afluenți varicoase success and successfully eliminate all GSV afluenți varicoase incompetent pathways often described as technical successand the success of the adjunctive procedures GSV afluenți varicoase to eradicate any coexistent incompetent tributary veins after ELA.
With ELA, in most cases the first cm of the treated vein beyond the SFJ or SPJ remains patent as treatment is begun just below this level.
Post-ELA patency of segments less than 5 cm long beyond the junction are the most common form of anatomical failure. Clinically, in spite of this, nearly all of these patients benefit from the procedure. However, the patent stump of GSV is usually connected to a saphenous tributary, which, over time, may reflux and be the source of a clinical recurrence. Less successful closure of the proximal vein verschiedene răni flebologie weiterer may be related to insufficient thermal injury to this portion that is generally of larger caliber and less likely to develop spasm during tumescent anesthetic administration and consequently more difficult to empty.
As a result, it is less likely to develop good device and vein wall apposition in this segment, which is thought important for optimal vein wall energy deposition to achieve successful ablation.
Patients with a high body mass index have been shown to have a higher rate of failure with laser. ELA success has been demonstrated in a retrospective data review to be independent of vein diameter in many studies. However, go here prospective confirmation of this conclusion has not been performed. Clinical outcomes from varicose vein ablation can be quantified by numerous reporting systems, including the Clinical, Etiologic, Anatomic, Pathophysiologic CEAP classification, the revised Venous Clinical Severity Score VCSSand several patient reported metrics including generic instruments such as the SF and several disease-specific instruments such as GSV afluenți varicoase Aberdeen Varicose Vein Questionnaire AVVQChronic Venous Insufficiency Questionnaire CIVIQ 2, Venous Insufficiency Epidemiological and Economic Study VEINESand Varicose Veins VV Symptoms Questionnaire VVsymQ.
The VVsymQ may be the best patient-reported GSV afluenți varicoase because it has been GSV afluenți varicoase by the FDA for use in device and drug trials. Ulcer healing has been induced after ELA. Several small comparison studies have evaluated the outcomes of laser ablation and surgery.
No tumescent anesthetic was used. Early pain was similar for both procedures, click to see more bruising and swelling were worse GSV afluenți varicoase surgery. APG improvements were equivalent in both groups. By 12 weeks, both groups had similar improvements in quality of life and in an objective assessment of the severity of their venous disease.
The VCSS improvement was significant compared with the pretreatment assessment and similar for both groups of patients. In addition, patient satisfaction, analgesia use, and the duration of days before return to work were significantly better for the laser-treated group. Initial technical successes were equivalent. ELA also showed decreased postprocedure varice constipație and earlier return to work than surgery.
Since its introduction, ELA has replaced ligation and stripping procedures of the GSV and SSV to eliminate reflux.
The procedure has been validated to result in reliable GSV afluenți varicoase of saphenous vein reflux, is safe, well tolerated, and durable. In addition, it has been shown to produce less periprocedural pain, shortening the recovery to allow for earlier return to work. Proebstle TM, Sandhofer M, Kargl A, Gul D, Rother W, Knop J.

Sections Varicose Vein GSV afluenți varicoase Gravide femeile pentru exercițiu cu varice Endovenous Laser Therapy. Overview Chronic venous disorders CVDs of the lower extremity are common problems caused by venous hypertension, which is commonly the result of reflux in one or more of the saphenous veins GSV afluenți varicoase their primary tributaries.

Corona phlebectasia, eczema, and pigmentation. Superficial phlebitis SVT in varicose veins. Intrafascial or epifascial vein segment meeting other anatomical criteria that can be pushed away from the skin with GSV afluenți varicoase anesthetic. Reflux responsible for venous hypertension leading to the clinical abnormalitiesAmbulatory patient without contraindication. Contraindications The contraindications to endovenous treatment are listed below. Patients who are pregnant or breastfeeding concerns related to anesthetic use and heated blood effluent that GSV afluenți varicoase pass through the placenta to the fetus.
Obstructed deep venous system inadequate to support venous return after ELA. Liver dysfunction or allergy making it impossible to use a local anesthetic cold GSV afluenți varicoase may be useful as an alternative. Allergy to both amide and ester local anesthetics cold saline may be an alternative.
Severe uncorrectable coagulopathy ELA is safe with warfarin use if the international normalized pe varice uter forum is between 2 GSV afluenți varicoase 3. Severe hypercoagulability syndromes where risk of treatment outweighs potential benefits despite prophylactic anticoagulants. Inability to adequately ambulate after the procedure. Thrombus or synechiae in the vein or tortuous vein making passage of an endovenous device impossible unless multiple access points are chosen.
Anesthesia Tumescent anesthetic, when used in phlebology, describes the use of large volumes of dilute anesthetic solutions that are infiltrated into the perivenous space of the veins to be treated. Equipment Basic equipment and supplies for ELA are listed below.
Procedure table that can tilt to Trendelenburg and reverse Trendelenburg. Sterile gowns, gloves, masks, drapes, gauze. Ultrasound gel, sterile ultrasound probe and cord cover.
Positioning Access to the target vein should be performed with the patient in the supine position. Technique ELA procedure for through the sheath laser fiber kits Perform preprocedural DUS for mapping of the venous segments to be treated. Mark the GSV afluenți varicoase of the vein s to be treated and important anatomical landmarks associated with the ablation on the skin, including the proposed venous access site s and deep vein junctions.
The access site is ideally at the inferior end of the incompetent segment or segments of the treated vein. In most cases, the entire incompetent segment s can be treated with 1 puncture.
If microphlebectomy will be performed along with ELA, the veins to be removed should GSV afluenți varicoase marked at this time as well. Prepare the operative tray and equipment.
Aside from the thermal ablation device continue reading a venous access kit, only basic supplies such as gauze, a sterilizing solution, sterile barriers, and the tumescent GSV afluenți varicoase, with delivery syringes and GSV afluenți varicoase and GSV afluenți varicoase ultrasound probe cover, are needed. Carry out sterile preparation and draping of the leg to be treated.
Preprocedural antibiotics are not necessary in almost all circumstances as the procedure is performed sterilely and is considered clean. Visualize the access site with DUS. Placing the patient in a reverse Trendelenburg or partly sitting position prior to the venous puncture keeps the vein more distended and may facilitate venous access.
Anesthetize the access site. Nick the skin GSV afluenți varicoase large enough to facilitate entry of the sheath through the skin. Insert the access needle into the great saphenous vein GSV under sonographic guidance.
Cutdown is rarely needed and usually only if percutaneous access fails. Confirm intravenous placement with ultrasonography. Place the introducer sheath over the wire. Position the sheath for ELA to the GSV afluenți varicoase point for ablation. Some physicians typically advance the ELA sheath beyond the starting point and later withdraw it with the laser fiber to the starting spot.
The movement of withdrawal helps GSV afluenți varicoase to accurately GSV afluenți varicoase the tip and position it at the starting point. Remove the wire and its dilator if one is used with the sheath. Check for venous return by aspirating the syringe attached to the sheath and flush. Recognize that the sheath tip may be against the vein wall and may not aspirate freely.
Also realize that when flushing, microbubbles of air introduced into the vein may produce an acoustic shadow that may limit the ability to see venous detail and device positions. Introduce the laser fiber into the sheath so that the fiber reaches the sheath tip. There is GSV afluenți varicoase a mark on the fiber to show this.
Then fix the laser fiber and carefully pull back the sheath to expose about 2—3 cm of fiber. Then withdraw the entire sheath-laser fiber to the ablation starting spot. Fine tune the location of the tip of the laser fiber to just below the superficial epigastric vein, anterior accessory GSV AAGSVor other large normal junctional vein for the GSV, and just below the thigh extension junction GSV afluenți varicoase the short saphenous vein SSV for SSV ablations.
Some operators choose to position the laser fiber cm below the saphenofemoral junction SFJ without consideration of the position of the junctional branches. No go here support superiority of any of the above procedures in terms of ablation success, junctional recurrences, or common femoral vein thrombosis post procedure.
See the image below. Longitudinal sagittal click the following article ultrasound image of the saphenofemoral junction during the positioning of the tip of a laser fiber during an endovenous laser ablation. The laser tip is in the greater saphenous vein GSV just beyond the superficial epigastric vein SEV origin and is marked by the arrow. Pearls Technique considerations The amount of thermal energy delivered is correlated to the success of ELA.
Complications Adverse events and complications Adverse events following ELA occur, but almost all are minor. Follow-up Care and Outcomes Postoperative Care and Instructions Postoperative care is designed to improve efficacy and minimize side effects and the risk of complications.

GSV afluenți varicoase
The great saphenous vein GSValternately " long saphenous vein " is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb. The great saphenous vein originates from where the dorsal vein of the big toe the Hallux merges with the dorsal venous arch of the foot.
After passing in front of the medial malleolus where continue reading often can be visualized and palpatedit runs up the medial side of the leg. At the knee, it runs over the posterior border of the medial epicondyle of the femur bone.
The GSV then courses anteriorly to lie on GSV afluenți varicoase anterior surface of the thigh before entering an opening in the fascia lata called the saphenous opening. It forms an arch, the saphenous arch, to join GSV afluenți varicoase common femoral vein in the region of the femoral triangle at the sapheno-femoral junction. At the ankle it receives branches from the sole of the foot through the medial marginal vein ; in the lower leg it anastomoses GSV afluenți varicoase with the small saphenous veincommunicates by perforator GSV afluenți varicoase Cockett perforators with the anterior and posterior tibial veins and receives many cutaneous veins; near the knee it communicates with the popliteal vein by the Boyd perforator, in the thigh it communicates with the femoral continue reading by perforator veins GSV afluenți varicoase perforator and receives GSV afluenți varicoase tributaries; those from the medial and posterior parts of the thigh frequently unite to form a large accessory saphenous vein which joins the main vein near the sapheno-femoral junction.
Near the fossa ovalis it is joined by the superficial epigastricsuperficial circumflex iliac veinand superficial external pudendal veins. The thoracoepigastric vein runs along the lateral aspect of the trunk between the superficial epigastric vein below and the lateral thoracic vein above and establishes an important communication between the femoral vein and the axillary vein.
Pathology of the great saphenous vein is relatively common, but in isolation typically not life-threatening. The vein is often removed by cardiac surgeons and used for autotransplantation in coronary artery bypass operationswhen arterial grafts are not available or many grafts are GSV afluenți varicoase, such as in a triple bypass or GSV afluenți varicoase bypass.
The great saphenous vein is the conduit of choice for vascular surgeons  when available, for doing peripheral arterial bypass operations [ see vascular bypass ] because it has superior long-term GSV afluenți varicoase compared to synthetic grafts PTFEPETE Dacronhuman umbilical vein grafts or biosynthetic grafts [Omniflow].
Often, it is Mă ulcer trofice in situ in placeafter tying off smaller tributaries and destruction of the venous valves with a device called valvulotomee. Removal of the saphenous vein will not hinder normal circulation in the leg. The blood that previously flowed through the saphenous vein will change its course of travel. This is known as collateral circulation. The saphenous nerve is a branch of the femoral nerve that runs with the great saphenous vein and can be damaged in surgery on the check this out. When emergency resuscitation with fluids is necessary, and standard intravenous access cannot be achieved due to venous collapse, saphenous vein cutdown may be necessary.
