Retropubic FemoraleFemoral Bypasses have Superior Outcomes Compared to Grafts Tunneled Subcutaneously

A femoral–femoral bypass is often used to revascularize lower extremities or as an adjunct to endovascular aneurysm repair. We hypothesized that grafts tunneled retropubically in the space of Retzius would be more resistant to infection because of the deeper tunnel and have better long-term patency owing to a linear course with less propensity for kinking compared with subcutaneously tunneled grafts.
