[Results of in situ arterial thrombolysis by the combination of urokinase and lysyl plasminogen in acute arterial occlusive diseases of the lower limbs].

35 patients with acute arterial occlusions [27] and graft thromboses [8], responsible for severe and recent ischemia, were treated by fibrinolytic therapy (Urokinase: 1 000 units/kg/hour, and Lys Plasminogen). These drugs were delivered at the site of occlusions using a 5 French catheter. Angiographically, initial success was obtained in 30 patients (85%) and a significant clinical benefit persisted 5 months later, in 20 patients (57%). 4 distal embolisms during the treatment were noted, and one woman died a few hours after the withdrawal of an axillary catheter of a cerebellar infarction. Only two minor (6%) and one severe (3%) groin hematoma were encountered. No patient had at any moment a fibrinogen concentration lower than 1 g/l. Thus, the thrombolytic treatment used in the study appears as effective as locally administered Streptokinase but better tolerated.
