The Anatomy of the Superficial Inferior Epigastric Artery: Cautious Optimism and Rightful Reluctance for the Championing of a Minimally Morbid Abdominal Flap.

Abstract

The Superficial Inferior Epigastric Artery (SIEA) flap has gained interest due to its potential as an abdominal breast reconstruction flap that incurs minimal donor site morbidity. Historical descriptions of its anatomy however paint the artery as small in calibre, with a restrictive angiosome and a high agenesis rate. This review examines the most contemporary anatomical data of the SIEA across clinical, cadaver and radiological modalities and balances the promise of encouraging anatomical data against the clinical practicalities of consistently and safely raising an SIEA flap.
