Short-term efficacy and safety of radiofrequency ablation for treatment of varicosis of great saphenous vein / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the short-term efficacy and safety of radiofrequency ablation (RFA) for treatment of varicosis of great saphenous vein. Methods Data of 17 patients (26 limbs) with great saphenous varicose veins treated with RFA under guidance of ultrasound were analyzed retrospectively, including 1 week before RFA, immediately after RFA as well as 1,3 and 6 months post operation. Results The occlusion rate of great saphenous vein was 100% (26/26) immediately, 1, 3 and 6 months after operation. The mobility of the limbs improved 3 and 6 months after operation compared with 1 week before operation (both P<0.05), the pain was relieved 6 months after surgery compared with 1 week before surgery (P<0.05). All grades in clinic-etiologic-anatomic-pathophysiological classification (CEAP) and revised venous clinical severity score (rVCSS) of limbs 1, 3, 6 months after operation were lower than 1 week before RFA(all P<0.01). During 6 months' follow up, subcutaneous cord stiff vein occurred in 7 limbs, saphenofemoral junction discomfort occurred in 1 limb, while subcutaneous hemorrhage developed in 3 limbs. Conclusion: RFA is effective for treatment of varicosis of great saphenous vein with few complications.
