Chronic Limb Ischemia due to Thrombosis of an Aneurysmal Degeneration of the Autogenous Vein Graft: A Case Report

Nonanastomotic aneurysmal degeneration of a great saphenous vein graft is an unusual condition, despite the common use of this conduit in arterial reconstructions. Vein grafts are at risk of degenerative changes, but the real cause remains unknown. Postoperative graft surveillance with duplex ultrasound scanning is important for maintaining patency of the venous graft. We present a rare case of chronic limb ischemia due to partial thrombosis of an aneurysm of the great saphenous vein graft.
