EVLT
From Wikipedia, the free encyclopedia
EVLT (Endovenous laser therapy) is a minimally invasive image-guided technique in which a catheter bearing a laser fiber is inserted under ultrasound guidance into the long saphenous vein through a small puncture at the level of the knee. The catheter is then advanced (also under ultrasound guidance) to the level of the groin and the laser activated resulting in obliteration of the saphenous vein. The catheter is then slowly withdrawn and the saphenous vein is ablated along its entire length. Foam sclerosant may be added through the catheter as required to treat large side branches. The treatment, which is performed without sedation, using local anesthetic typically takes less than an hour and the patient typically walks out under his or her own power. A compression stocking and bandage is applied which must be worn for 48 hours continuously. The compression bandage is removed after 48 hrs to allow the patient to shower. The compression stocking must be worn for 2 weeks while the patient is awake.
Results to date suggest a cure rate of over 95%.
