ABSTRACT
BACKGROUND: Microwave ablation is considered to be safe for treatment in chronic venous disease patients, but data is lacking about its long-terms results. The present study aimed to evaluate the effectiveness of endovenous microwave ablation. MATERIAL AND METHOD: From January 2009-June 2012, 100 patients underwent endovenous microwave ablation. Demographic data, post-operative complication, and CIVIQ-2 questionnaire scores were recorded. Microwave energy was set at 50-65 watts and the pull back speed was 3 cm/minute. RESULTS: C2 was a common finding, (59.6%). Mean follow-up time was 25.2 months and the most immediate complication was numbness (32.1%) with permanent numbness at 3.8%. Quality of life as determined by CIVIQ-2 score changedfrom 32 before operation to 24 after operation (p<0.001). Complete venous occlusion rate was 79.8% and the rate of partial venous occlusion with no venous reflux was 8.7%. CONCLUSION: Endovenous microwave ablation can be used safely. It could be an alternative treatment for patients with chronic venous disease.

AIM: This study aims to investigate the application of the microwave generator to treat the patients with varicose veins. MATERIALS AND METHODS: Phase 1: Explanted saphenous veins in subcutaneous layer of the pork meat were ablated at 0, 40, 50, 60, and 70 W. Phase 2: The forelimb veins and the hindlimb arteries of a 40-kg swine were ablated at 50 and 60 W. Phase 3: The patients were treated with endovenous microwave ablation at 50 W. RESULTS: Phase 1: Perivenous tissue injury was found in groups 50, 60, and 70 W. Phase 2: Less perivenous tissue injury was found in group 50 W. Phase 3: Complete venous occlusion rate was 65% and venous reflux-free was 85% in 1 year. No severe complication was found. CONCLUSIONS: The microwave generator with 50-W power setting could be used to ablate the varicose veins safely.
