About

The Rio Study is a randomized, double blinded German- Swiss- Austria multi-centre trial on the efficacy and safety of ReoPro together with interventional recanalization of TASC D lesions in the SFA and popliteal artery.

Full description

Purpose: The RIO trial is designed to test the efficacy of GP IIb/IIIa blockade on subacute reocclusions in patients with interventional recanalization of chronic occlusions in the superficial femoral and popliteal artery.

Methods: A total of 420 patients will be randomly assigned to ReoPro or placebo. Patients will be eligible for randomisation with occlusions longer than 5 cm. Doppler ultrasound follow-up will be at 30 days, and after 6, and 12 months.

Inclusion criteria

Patients with a history of peripheral artery disease with superficial femoral or popliteal artery occlusion, which mandates PTA or stent administration as first treatment modality. The history of peripheral artery occlusion has to be at least 6 weeks, and the target vessel occlusion has to be more than 5 centimeters in length.
Age between 18 and 90 years
