概要	BACKGROUND:This study was performed to investigate the arterial and venous anatomy of superficial inferior epigastric artery (SIEA) flaps using multidetector-row computed tomography angiography (MDCTA). We hypothesized that applicability of the SIEA flap has been underestimated in previous studies.METHODS:We retrospectively analyzed the results of preoperative MDCTA of the bilateral lower abdominal walls in 72 consecutive patients. We assessed the presence and branching pattern of the superficial inferior epigastric artery, superficial inferior epigastric vein (SIEV), superficial circumflex iliac vein, and venae comitantes (VC) of the superficial inferior epigastric artery. We also assessed the internal diameter of the SIEA at its origin.RESULTS:The SIEA was present on 133 sides (92.4%), and the mean internal diameter was 2.0 mm. The internal diameter of the SIEA was ≥2.0 mm on 102 sides (70.8%). The VC drained into the superficial circumflex iliac vein on 68 sides (47.2%) and to the SIEV on 30 sides (20.8%).CONCLUSIONS:An internal diameter of the SIEA of ≥2.0 mm at its origin on preoperative imaging can be a good criterion for exploring the artery during lower abdominal flap harvest. The VC is the dominant drainage vein over the SIEV in some patients, and it communicates with the superficial circumflex iliac vein in almost half of patients. These findings can increase the safety of breast reconstruction with an SIEA flap.
