Perforator vein endovenous heat induced thrombosis after laser ablation of the great saphenous vein.

Endovenous heat induced thrombosis at the sapheno-femoral or sapheno-popliteal junction is a wellknown complication after superficial truncal vein endovenous laser ablation (EVLA). This report describes a rare thigh perforator vein thrombus propagation into the femoral vein after EVLA of the great saphenous vein.
