Free flap with reversed arterial flow in the leg: case report

A case of distal-third reconstruction of a leg with bone exposure is reported. A rectus abdominis muscle free flap, based on the inferior epigastric artery, was anastomosed to the distal stump of the anterior tibial artery with reversed flow. This technique is suggested as an option for microvascular reconstruction in the distal third of the leg. Anatomic and physiologic details are discussed.
