[Local thrombolysis in the treatment of acute ischemia of the leg].

The results of local low-dose thrombolytic treatments of 564 peripheral arterial occlusions were as follows: Embolic occlusions up to 6 weeks could be removed in 72.7%, the longer lasting occlusions in 42.3%. Thrombotic occlusions lasting up to 6 months were successfully treated in 58%, still older ones in 36.2%. The cumulative patency after 5 years was 89.5% in embolic and 58.8% in thrombotic occlusions. Therefore, the differential therapy of acute peripheral ischemia has to be thought over anew together with the vascular surgeons.
