Infra\u2010inguinal bypass (IIB) surgery remains a robust revascularization option in these patients.

Data regarding patient demographics, co\u2010morbidities, pre\u2010operative investigations, bypass characteristics, and discharge outcomes were collected. Surveillance ultrasound scans were reviewed to gain information on graft patency and compliance up to 2\u2009years post\u2010operatively. The primary outcome was graft failure.
