Late thrombotic occlusion of saphenous vein grafts: Successful recanalization using thrombolytic therapy

We report two cases in which thrombosis was the primary cause of vein graft occlusion many years after bypass surgery. Both displayed minimal thrombolysis immediately after a selective infusion of streptokinase but were patent when reimaged hours later. Such therapy may be helpful when graft occlusions are associated with a large volume of thrombus.
