[Loco-regional transcatheter thrombolysis].

Eight cases of recent arterial thrombosis (average time of symptoms: 11 days) are considered: 2 popliteal and 6 prosthetic thromboses (2 aorto-bifemoral and 4 femoropopliteal by-passes). After percutaneous catheterization, with catheter tip either in contact with or inside the thrombus, urokinase was locally injected (200,000 UI bolus, and 75,000 UI with slow infusion for 24 +/- 72 hours); general heparin treatment was also administered. PTA was employed in 2 cases (1 surgical anastomosis and 1 popliteal thrombosis). Arterial recanalization was always obtained within 72 hours in 2 aorto-bifemoral and in 1/4 femoropopliteal by-passes. Patency was also obtained in the 2 popliteal thrombosis.
