This article aims to investigate the critical role of the venous‐perforator in the decision‐making process of choosing the best suitable perforator‐complex in a deep inferior epigastric perforator (DIEP) flap. Methods Forty consecutive DIEP breast reconstructions were pre‐operatively evaluated by CT‐Angiography to identify the dominant and centrally located abdominal wall perforators. The CTA results were used as a guide to conduct a Color‐Duplex‐Ultrasound examination that was mainly focused on investigating the accompanying venous‐perforator. In group‐A ( n = 20) perforator‐complex selection was based on the size of the arterial‐perforator, whilst in group‐B ( n = 20) it was based on the size of the venous‐perforator. Results All single perforator‐complex DIEP flaps survived. No significant differences were recorded concerning the size of arterial‐perforator between the two groups; however the size of venous‐perforator was significantly larger in group‐B ( P < 0.05). In group‐A, four flaps showed vascular compromise intraoperative that was salvaged by flap supercharge with the superficial inferior epigastric system. In contrast, in group‐B, all flaps were re‐vascularized uneventfully ( P < 0.05). Physical examination revealed a palpable mass in one patient and ultrasound investigation added three cases with a firm area of scar tissue in group‐A, but no fat necrosis was detected in group‐B ( P < 0.05). Conclusions The CTA‐guided duplex ultrasonography could direct the perforator‐complex selection according to the size of the venous‐perforator, and may reduce the intraoperative problems and the incidence of fat necrosis. © 2013 Wiley Periodicals, Inc.
