Retrograde approach for endovascular salvage of an infrapopliteal vein bypass.

Endovascular treatment through femoropopliteal and infragenicular percutaneous transluminal angioplasty, both in native vessels and in bypass salvage, has been an emerging technique in recent years. However, in some cases, a difficult anterograde access in distal occlusions has limited the technical success of this procedure. Combined subintimal arterial flossing with antegrade-retrograde intervention is used as a resource technique to obtain precise recanalization in these cases. Here, we present the case of a retromalleolar access of the posterior tibial artery, based on subintimal arterial flossing with antegrade-retrograde intervention technique, to achieve femoral-posterior tibial bypass salvage.
