Objective To provide the anatomical basis for the appl ication of the superficial inferior epigastric artery flap. Methods Ten cadavers which were immersed in formal in less than 6 months and were perfused by red latex were used in this study. There were 8 males and 2 females with an average age of 58 years (range, 35-78 years). The origin, course, branch,
distribution, diameter, pedicle length, and neighbour of superficial inferior epigastric artery and vein were observed in the 2 sides of inguinal region. Results In these series of 10 cadaver (20 sides) dissections, the superficial inferior epigastric artery was identified in 18 sides, which average cal iber was 1.48 mm with a mean vascular pedicle length of 4.80 cm. In 11 sides, the superficial inferior epigastric artery arose aspart of a common trunk with one or more other vessels; in other 7, it originated from the femoral. There were 4 branch modes of superficial inperior epigastric artery: single trunks (5 sides), double ramification (3 sides), single lateral ramification (7 sides), and single medial ramification (3 sides). The superficial inferior epigastric vein was observed in 20 sides, which average cal iber was 2.33 mm with a mean sides pedicle length of 5.45 cm. In 8 sides, the venous drainage was as an individual vein; in 12 sides, both patterns were observed (a pair of venae comitantes and an individual vein). Conclusion The inferior epigastric artery flap can be appl ied to microsurgical flap transfer, potentially in breast reconstruction, phalloplasty, reconstruction of head, neck and four l imbs defects.
