Prognostic risk factors for loss of patency after femoropopliteal bailout stenting with dual-component stent: results from the TIGRIS Italian Multicenter Registry.

The bailout stenting of the femoropopliteal segment with third-generation nitinol stents is a safe and effective option in case of recoil, dissection or residual stenosis not responding to PTA. Critical limb ischemia and history of previous major treatment at the same level are significant prognostic factors for patency loss during FU.
