Chronic venous disease treated with endovenous microwave ablation: long-terms results and quality of life

J Med Assoc Thai. 2014 Nov:97 Suppl 11:S76-80.


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.
