Scientific titleDutch randomised trial comparing standard catheter-directed thrombolysis versus ultrasound-accelerated thrombolysis for thromboembolic infra-inguinal disease (DUET)
Study acronymDUET
Study objectivesThe use of ultrasound-accelerated catheter-derived thrombolysis in patients with recently (between 1 and 7 weeks) thrombosed infra-inguinal native arteries or bypass grafts will significantly reduce (at least 12 hours) therapy time compared to standard thrombolysis alone without increasing complication rate.
Ethics approval(s)Ethics Committee of the St. Antonius Hospital Nieuwegein, 13/10/2009, ref: R-09.17A
Health condition(s) or problem(s) studiedThromboembolic infra-inguinal disease
InterventionGroup A (standard thrombolysis):
During angiography a thrombolysis delivery catheter will be navigated proximally into the thrombus, followed by a control angiography at standardised intervals. During each control angiography the tip of the thrombolysis catheter will be repositioned proximally in the remaining thrombus.

Group B (ultrasound-accelerated thrombolysis):
During angiography a thrombolysis delivery catheter will be navigated into the thrombosed segment with a guide wire in such a way that the treatment zone traverses the entire clot and the tip lies distal to the thrombus. After final positioning, the guide wire will be exchanged for a matching ultrasound-core wire and thrombolytic therapy will be started. Likewise a control angiography will be performed at standardised intervals.

The total duration of follow-up will be 1 month.
Intervention typeProcedure/Surgery
Primary outcome measureDuration of catheter-derived thrombolysis needed for uninterrupted flow in the thrombosed infra-inguinal native artery or bypass graft with outflow via at least one crural artery.
Secondary outcome measures1. Technical success defined as complete lysis of the thrombus of the native artery or bypass graft without distal thrombo-embolic complications
2. Number of units urokinasis needed for uninterrupted flow in the thrombosed infra-inguinal native artery or bypass graft with outflow via at least one crural artery
3. Thrombolysis induced haemorrhagic complications
4. 30-day mortality
5. Duration of hospital admission
6. Costs of hospital admission
7. 30-day patency of the target artery or bypass, as evidenced by magnetic resonance angiography (MRA)
8. Drop of serum fibrinogen concentration to below 1.0 g/L during procedure
7. Conversion to open surgery
8. Distal thromboembolic complications
9. Other complications
Overall study start date01/11/2009
