PURPOSE: This study was designed as a prospective multicenter randomized comparison of procedure-related complications, patient recuperation, and quality-of-life outcomes between patients undergoingvein stripping with high ligation and patients undergoing great saphenous vein (GSV) obliteration with temperature-controlled radiofrequency ablation without adjunctive high ligation (Closure procedure). METHODS:Eighty-five patients (86 limbs) from five sites (France, 2; Austria, 1; United States, 2) were randomly allocated to undergo radiofrequency obliteration (RFO) or stripping and high ligation (S&L). Final analysis included data for 44 limbs in the RFO group and 36 limbs in the S&L group. Follow-up examinations were performed at 72 hours, 1 week, 3 weeks, and 4 months. All patients completed the CIVIQ2 quality-of-life (QOL) questionnaire and underwent clinical and ultrasound examinations at each follow-up visit. RESULTS:Immediate success on the day of treatment was reported for 95% (42 of 44) of limbs in the RFO group and 100% (36 of 36) of limbs in the S&L group. In seven RFO limbs (16.3%) a scan obtained 72 hours after the procedure showed flow in the proximal GSV. Five of these segments had reflux in the open segment. At 1 week two of these closed, and an additional segment closed at 3 weeks. In no cases did flow reappear after complete occlusion of the GSV. Time to return to normal activities was significantly less in the RFO group (mean, 1.15 days; 95% confidence interval [CI], 0.05-2.34) compared with the S&L group (mean, 3.89 days; CI, 2.67-5.12; P =.02). In the RFO group, 80.5% of patients returned to routine activities of daily living within 1 day, compared with 46.9% of patients in the S&L group (P <.01). Patients in the RFO group were able to return to work in 4.7 days (CI, 1.16-8.17), compared with 12.4 days (CI, 8.66-16.23) for the S&L group (P <.05). Analysis of the QOL surveys showed statistically significant differences in favor of the RFO group for global score and pain score during follow-up. The magnitude of the difference, however, progressively decreased between 1 week and 4 months. CONCLUSIONS: In the absence of significant complications, such as deep vein thrombosis and pulmonary embolism, severe neuritic sequelae, and skin burns, there are significant early advantages to endovascular obliteration of the GSV compared with conventional vein stripping.
