Abstract
BACKGROUND: Endovenous laser ablation (EVLA) is a minimally invasive technique for treating great saphenous vein (GSV) reflux for several years. We report our experience with EVLA and evaluate its effectiveness. METHODS: A consecutive series of patients (639 women [60%] and 421 men [40%], age 23 to 79 years) were treated by EVLA for GSV reflux and tributary varices at our institution. A questionnaire was used to assess preoperative and postoperative symptoms. The primary outcomes for assessing safety were mortality and morbidity, including laser-related adverse events, postoperative infection, thrombotic events, etc. Effectiveness was assessed by the obliteration of the vein, disappearance of varicosities, and so on. RESULTS: All patients tolerated the procedure well, recovered uneventfully, and returned to daily activities and work 3 days and 10 to 14 days, respectively, after the operation. Treatment with EVLA plus ligation of the GSV resulted in occlusion in all cases at 2 weeks follow-up and in 1169 of 1186 (99%) at 6-month follow-up; the rate of retreatment was low (36/1186). Complications were minor and improved quickly. CONCLUSIONS: EVLA can reduce and relieve symptoms associated with varicose veins and achieve cosmetic goals. Vein emptying before exposure to laser energy and compression treatment afterwards may improve results.
