Superficial Inferior Epigastric Artery Flap Salvage Technique Using Deep Inferior Epigastric Artery Graft

Summary: Superficial inferior epigastric artery (SIEA) flap salvage remains challenging, particularly in cases of arterial insufficiency due to vessel spasm, pedicle kinking, or thrombosis. The already small, short SIEA pedicle, in addition to its inherent tendency toward spasm, renders the SIEA flap more difficult to manage when anastomotic revision is required. Furthermore, arterial thrombosis will cause dilation of the internal mammary artery, exacerbating vessel mismatch. In our previously published experience with 145 SIEA flaps, no flap with postoperative arterial thrombosis was salvageable. Following this experience, a new salvage technique using deep inferior epigastric artery grafts has been utilized and is described here.
