Thrombus Extension into the Common Femoral Vein after Endovenous Ablation of the Greater Saphenous Vein for the Treatment of Venous Insufficiency

Abstract

Increasingly, endovenous ablation of the greater saphenous vein (GSV) is used for the treatment of symptomatic varicose veins. The propagation of thrombus can result in a “tail of thrombus” within the common femoral vein (CFV). In two cases, patients were treated with low molecular weight heparin and re-imaged within 1 week. In both cases, complete resolution of the thrombus was confirmed, and anticoagulation was discontinued. Thrombus extension into the CFV after endovenous ablation may be safely treated with short-term anticoagulation and followed by duplex ultrasound. If unresolved, standard deep vein thrombosis anticoagulation is indicated.
