Interventions

Group A (US-accelerated thrombolysis with 100.000 IU urokinase/h): During angiography an US-enhanced thrombolysis delivery catheter will be navigated into the thrombosed arterial segment over a guid

Design outcomes

Primary

MeasureTime frame
Occurrence of hemorrhagic complications.

Secondary

MeasureTime frame
1. Technical success defined as >95% lysis of thrombus within 48 hours 2. Duration of catheter-derived thrombolysis needed for uninterrupted flow in the thrombosed infra-inguinal bypass graft or native artery with outflow via at least one crural artery 3. Amount of Urokinase (in IU) needed for uninterrupted flow. 4. 30-day mortality 5. 30-day patency of the target artery or bypass, as evidenced by Colour Flow Doppler Ultrasound (Duplex) 6. Conversion to open surgery 7. Distal thrombo-embolic complications
