Introduction We previously reported our technique of ultrasonography-guided, catheter-assisted foam sclerotherapy of the long saphenous vein for treatment of primary varicose veins. In this study, we present the technical results, based on follow-up duplex images, and patient-reported symptom improvement and satisfaction.
Methods All patients treated with ultrasonography-guided, catheter-assisted foam sclerotherapy between March 2006 and August 2007 were included in this review. Prospectively collected clinical data and follow-up postoperative duplex examinations at one day, six months and 12 months were reviewed. Telephone interviews with a standard questionnaire were conducted.
Results During the study period, 66 lower limbs in 62 patients were treated using the described technique. The median follow-up period was 12 months (range one day to 38 months). Successful occlusion rate was 98% at six months and 80% at 12 months for patients who attended follow-up duplex imaging. Seven patients underwent a second procedure. Patient satisfaction was good, with 96% reporting symptom improvement.
Conclusion Ultrasonography-guided, catheter-assisted foam sclerotherapy is safe, minimally invasive and yields good medium-term occlusion rates of the treated veins.
