RFA und Thrombophlebitis

Feb 15, Author: When the refluxing circuit involves failure of the primary valves at the saphenofemoral junction, treatment options for the patient are limited, and early recurrences are the rule rather than the exception. See Superficial Venous Insufficiency: Varicose Veins and Venous Ulcersa Critical Images slideshow, to help identify the common risk factors and features of this Bein Varizen Volk and its management options.

In the historical surgical approach, ligation and division of the saphenous trunk and all proximal tributaries are followed either by stripping of the vein or by avulsion phlebectomy. Proximal ligation requires a substantial incision at the groin crease. Stripping of the vein requires additional incisions at the knee RFA und Thrombophlebitis below and is associated with a high incidence of RFA und Thrombophlebitis surgical complications.

Avulsion phlebectomy requires multiple 2- to 3-mm incisions along the course of the vein and can cause damage to adjacent nerves and lymphatic RFA und Thrombophlebitis. Endovenous ablation has replaced stripping and ligation as the technique for elimination of saphenous vein reflux.

One of the endovenous techniques is a radiofrequency-based procedure. Newer methods of delivery of radiofrequency were introduced in Endovenous procedures are far less invasive than surgery and have lower complication rates. The procedure is well tolerated by patients, and it produces good cosmetic results.

Excellent clinical results are continue reading at years, and the long-term efficacy of the procedure is now known with 10 years of experience. Endovenous techniques endovenous laser therapyradiofrequency ablation, and endovenous foam sclerotherapy clearly are less invasive and are associated with fewer complications compared with more invasive surgical procedures, with comparable or greater efficacy.

The original radiofrequency endovenous ablation system worked by thermal click of venous tissues using electrical energy passing through tissue in the form of high-frequency alternating current. This current was converted into heat, which causes irreversible localized tissue damage. Radiofrequency energy is delivered through a special catheter with deployable electrodes at the tip; the RFA und Thrombophlebitis touch RFA und Thrombophlebitis vein walls and deliver energy directly into the tissues without coagulating blood.

The newest system, called ClosureFast, delivers infrared energy to vein walls by directly RFA und Thrombophlebitis a catheter tip RFA und Thrombophlebitis radiofrequency energy.

As the vein RFA und Thrombophlebitis denatured by heat, it contracts around check this out catheter.

With the previous-generation radiofrequency system, as shrinkage and compaction of tissue occurred, impedance was decreased which decreased heat generation; however, this is no longer the case. Only the temperature of the catheter metal core is monitored as it delivers heat to the vessel wall in second increments. Previously, the radiofrequency generator RFA und Thrombophlebitis be programmed to rapidly shutdown when impedance rose, RFA und Thrombophlebitis assuring minimal heating of blood but efficient RFA und Thrombophlebitis of the vein wall.

Heat delivered to click at this page vein wall causes the vessel to shrink in the treated area, and the catheter is gradually withdrawn along the course of the vein until the entire vessel has been treated.

This is performed in 7-cm segments. Many different radiofrequency ablation catheters are available for medical RFA und Thrombophlebitis, but the Closure catheter, manufactured by VNUS Medical Technologies, is the only commercially available radiofrequency ablation system designed for venous ablation.

The image below shows RFA und Thrombophlebitis Closure console, and the second image below shows 2 sizes of radiofrequency ablation catheters. RFA und Thrombophlebitis after treatment, biopsy specimens show a significant reduction in the size of the RFA und Thrombophlebitis lumen, with denudation of endothelium, thrombus formation, thickened vessel walls, loss of collagen birefringence, and inflammatory changes.

The zone of thermal damage is limited to 2 mm beyond the point of contact with the electrodes. The lumen is completely ablated in most areas, with some portions of the vessel demonstrating a small residual lumen containing organized fibrous thrombi.

Birefringence is present, and new collagen growth is RFA und Thrombophlebitis. Radiofrequency ablation catheters cannot be easily passed along a tortuous superficial vein; therefore, the procedure RFA und Thrombophlebitis principally of use RFA und Thrombophlebitis the treatment of truncal varicose veins, such as the great saphenous vein.

Radiofrequency ablation is also used with small saphenous vein incompetence. Duplex ultrasonography is used to confirm and map all areas of reflux and to trace the path of the refluxing great saphenous trunk from the saphenofemoral junction down the leg to RFA und Thrombophlebitis lower thigh or upper part of the calf. The vein, the saphenofemoral junction, RFA und Thrombophlebitis the anticipated entry point are marked in some way on the skin.

An appropriate just click for source point is selected just above or RFA und Thrombophlebitis below the knee, at a point permitting cannulation of the vessel with a gauge needle introducer. The leg is prepared and draped, and a superficial local anesthetic agent is used to anesthetize the site of cannulation.

Needle puncture of the vessel is guided by duplex ultrasonography. The Seldinger technique is used to place a guidewire into the vessel, and an RFA und Thrombophlebitis sheath is passed over the guidewire, which is removed. The ClosureFast catheter is passed through the sheath, and the tip is advanced to 2 cm below the saphenofemoral junction under duplex ultrasonographic visualization.

With ultrasonographic guidance, a local anesthetic agent is injected into the tissues surrounding the great saphenous vein above and within its fascial sheath. The anesthetic is injected along the entire course of the vein from the catheter insertion point to the saphenofemoral junction. In most patients, mL of lidocaine 0. Note the importance of delivering the RFA und Thrombophlebitis agent in the correct intrafascial location, with a volume sufficient to compress the vein link dissect it away from other structures, such nach der für Krampfadern nerves, along its entire length.

Duplex ultrasonography is used to position the catheter RFA und Thrombophlebitis 2 cm below the level of the terminal valve of the saphenofemoral junction. The catheter must not extend into the femoral vein because injury to the femoral vein may cause deep RFA und Thrombophlebitis thrombosis. If the temperature does not rise quickly, a malpositioned catheter tip should be strongly suspected.

In the new system, two second cycles are performed in the proximal section, after which the catheter is withdrawn 7 cm as per catheter markings. When proper tumescent anesthesia is applied, the patient should never experience a sudden heat sensation. If this happens, more anesthesia is injected.

Posttreatment duplex ultrasonography confirms the contraction of the vessel and the absence of flow along the entire length of the treated vessel. In the previous system, if persistent flow is observed, the procedure may be repeated immediately, provided the catheter still be easily passed along the vessel to the desired site of treatment.

In the new system of ClosureFast, the procedure is not repeated because the targeted vessel typically shows no flow. Compression is of vital importance after any venous procedure. Compression is effective in reducing postoperative bruising and tenderness, and it can also reduce the risk of venous thromboembolism in both the treated here and the untreated leg.

A class II to mm Hg gradient compression stocking is applied to the treated leg, and, if the RFA und Thrombophlebitis is willing, it RFA und Thrombophlebitis also applied to the RFA und Thrombophlebitis leg. Bed rest and lifting of heavy objects are forbidden, and normal activity is encouraged. RFA und Thrombophlebitis patient is reevaluated days after the operation, at which time duplex ultrasonography should demonstrate a closed greater saphenous vein and no evidence of thrombus in the femoral, popliteal, or deep veins of the calf.

At 6 weeks, an examination should reveal clinical resolution of truncal varices, and an ultrasonographic evaluation should demonstrate a completely closed vessel RFA und Thrombophlebitis no remaining reflux. If any residual open segments are noted, sclerotherapy is performed under ultrasonographic guidance. For patient education RFA und Thrombophlebitis, see Varicose Veins. Reported complications of the procedure are rare.

Local paresthesias can occur from perivenous nerve injury but are usually temporary. Thermal injury to the skin was reported in clinical trials RFA und Thrombophlebitis the volume of local anesthetic was not sufficient to provide a buffer between the skin and a particularly superficial vessel, especially below the knee.

Progression of thrombus from local superficial phlebitis has occasionally been observed when compression was not used. Published results show a high early success krankenkasse venen verkleben with a very low subsequent recurrence rate up to 10 years after treatment. Early and mid range results are comparable to those obtained with other endovenous ablation techniques. Krampfadern der Speiseröhre Klinik efficacy and lower morbidity have resulted in endovenous ablation techniques replacing surgical stripping.

The vein occlusion rate was A study by Bush et al indicated that perforating veins are the most frequent cause of recurrent varicose veins after radiofrequency or laser ablation. Of patients involved in the study, had a recurrence of varicose veins, with the median period to recurrence being 3 years. Among the patients who experienced recurrence, had undergone great saphenous vein ablation as their initial treatment, including 52 RFA und Thrombophlebitis had concurrently undergone small saphenous vein or anterior accessory great saphenous vein ablation.

It RFA und Thrombophlebitis also found that a higher rate of recanalization occurred with radiofrequency RFA und Thrombophlebitis than with the laser procedure. A study by Bozoglan et al also suggested that endovenous laser ablation may have some advantages over radiofrequency ablation of varicose veins. The study included 60 patients with bilateral saphenous vein insufficiency, each of whom had RFA und Thrombophlebitis leg treated with the radiofrequency procedure and the other treated with laser therapy.

The investigators found that the recanalization rate was 6. Advances in the treatment of varicose veins: Four-year follow-up on endovascular radiofrequency obliteration of great saphenous reflux.
