Thrombolysis of graft occlusion using high dose urokinase. An alternative to surgical treatment?

Abstract

Two cases of acute leg ischemia from unilateral occlusion of an aorto-bifemoral graft, treated with high-dose urokinase intra-arterial infusion, are reported. This therapy allowed identification of the cause of thrombosis, recanalization of the graft and planning of reoperation. Indications for intra-arterial thrombolytic therapy and advantages of urokinase vs streptokinase are discussed.
