This is a multicenter double-arm randomized trial investigating plain balloon angioplasty versus primary placement of self-expanding nitinol stents after endovascular recanalization of femoral CTOs. Study will recruit up to 200 patients to be adequately powered for detection of a significant difference in vessel patency after 1 year.
Primary placement of new-generation nitinol stents compared to plain old balloon angioplasty has shown encouraging long-term results in the femoropopliteal artery. However, there is complete lack of data about performance of new-generation nitinol stents in the treatment of chronic total occlusions (CTO) of the Femoral artery. This is a multicenter double-arm randomized trial investigating plain balloon angioplasty versus primary placement of self-expanding nitinol stents after endovascular recanalization of femoral CTOs. Study will recruit up to 200 patients to be adequately powered for detection of a significant difference in vessel patency after 1 year.
