To evaluate the efficacy in foam sclerotherapy of great saphenous vein varicose (GSVV) under ultrasound monitoring during the whole treatment.

Totally 39 cases of patients with GSVV between January 2014 and January 2015 in Harbin Second Hospital (with 3 patients had bilateral disease, a total of 42 limbs) were recruited. Twenty-six limbs have soreness, fatigue and other symptoms after activity, 31 limbs have skin pigment calm, 39 limbs have varying degrees of varicose vein. All patients have no lower extremity venous ulcer. Ultrasound monitored the whole process of injection foam sclerotherapy (3% polidocanol injection) of all the trunk of great saphenous vein. All patients were followed up at 1 week, 3 months and 12 months after operation.

All 42 patients were successfully treated by ultrasound monitored injection. Bilateral lower extremity varicose vein treatment intervals greater than 6 months. Deep venous thrombosis were not seen in all patients, 5 cases appeared occasional cough, 8 cases appeared lower limb skin redness. Totally 26 patients showed acid expansion, fatigue and disappeared after the limb activity; 39 patients with obvious limb varicose veins disappeared, of which 4 (4/39) of the distal end of the limb with mild varicose veins; 26 with limb skin pigmentation reduced. There were no serious complications in all patients.

Ultrasonic monitoring the whole process of injection foam sclerotherapy of GSVV is effective and no serious complications, pending further study.
