[Intra-arterial thrombolysis in peripheral bypass and arterial occlusions. Results and predictive factors for thrombolysis].

The purpose of the study was to reveal the association between successful intra-arterial thrombolysis in peripheral arterial and graft occlusions and the following factors: sex, age, symptoms, duration of symptoms, length of occlusion, conduit type, runoff and catheter localisation. Forty-six patients were treated with continuous intra-arterial infusion of streptokinase. Twelve patients were given tissue plaminogen activator (tPA). In the streptokinase-group successful lysis was achieved in 27 of 46 patients (59%). A significant association was found between successful thrombolysis and good runoff (p < 0.01). Catheter position above the occlusion resulted in lysis in only 1 of 11 patients. Lysis was achieved in nine of 12 patients (75%) treated with tPA. In this study, good runoff and intrathrombotic infusion were almost prerequisites for obtaining a positive immediate outcome. Other factors were less important.
