Common Iliac Artery to Below-Knee Popliteal Artery Bypass via Obturator Foramen in a Third-Time Reoperative Groin for Limb Salvage in Chronic Limb-Threatening Ischemia.

This case report presents the management of a 69-year-old man with an extensive history of peripheral vascular disease including 2 previous failed right femoral to distal bypasses and a left above-the-knee amputation who presented with right lower extremity rest pain and non-healing shin ulcers. A redo bypass was performed for limb salvage via the obturator foramen to avoid his extensively scarred femoral region. The postoperative course was uneventful and the bypass remained patent in the early period. This case demonstrates the usefulness of the obturator bypass to provide revascularization and avoid amputation in a patient with chronic limb-threatening ischemia and multiple failed bypasses.
