Leaking pseudoaneurysm of lower limb saphenous vein graft: a rare complication and its successful treatment by endovascular embolization

A rare complication after lower limb revascularization using a saphenous vein bypass graft in a crush injury patient where the saphenous vein graft was the sole supplying vessel to the leg is described; a pseudoaneurysm developed in the saphenous vein graft and caused active profuse bleeding through the surgical wound. The aetiology of this condition is uncertain but it could occur owing to slippage of ligature from one of the tributaries of the saphenous vein. The diagnosis was made by digital subtraction angiography. The pseudoaneurysm was successfully obliterated by glue embolization, which stopped the bleeding immediately, with preservation of distal flow, thereby salvaging the limb.
