Comparison of ultrasound results following endovenous laser ablation and radiofrequency ablation in the treatment of varicose veins.

Purpose: Superficial venous insufficiency is a common problem associated with varicose veins. In addition to classical symptoms, it may result in skin changes, venous ulcers and has a great impact on patients' health-related quality of life. In the last decade, minimally invasive techniques such as endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) have been developed as alternatives to surgery in an attempt to reduce morbidity and improve efficiency. The aim of this study is to evaluate the efficacy of EVLA and RF therapies in superficial venous insufficiency.

Material And Methods: Fifty legs belonging to 50 patients with symptomatic primary venous insufficiency were treated. 25 saphenous veins treated with 1470 nmdiode laser, while 25, saphenous veins treated with bipolar Radiofrequency Induced Thermotherapy (RF). All patients underwent postoperative duplex scanning within 6 month after the procedure and followed clinically, to determine the severity of the venous disease. Complications and occlusion rates were recorded.

Results: Total occlusion rates in RF and EVLA groups were 100% and was 100%, respectively. There was no significant difference between groups (p=0,140). Major complications such as skin burns, deep venous thrombosis have not been detected for both groups. 2 patients treated with EVLA had erythema (8%) and 1 patient had a pain sensation (4%). 1 patient in the RF group had erythema (4%), 1 had pain (4%) and 1 had a burning sensation (4%).

Conclusion: EVLA and RF therapies in saphenous vein insufficiency are effective, minimally invasive, safe, easy to use treatment modalities with good patient satisfaction and high occlusion rates.
