Outcomes of infrageniculate retrograde versus transfemoral access for endovascular intervention for chronic lower extremity ischemia

Infrageniculate access for REI can result in primary patency rates similar to those of antegrade interventions and does not compromise the access site. Technical failure is high in this initial experience and is mostly due to failed recanalization. Limb salvage may be achieved after technical failure with either repeated antegrade intervention or surgical bypass.
