Applied anatomy of the superficial inferior epigastric artery flap and its clinical significance in repairing head and neck defect
Objective To study anatomic features of the superficial inferior epigastric artery(SIEA) flap and explore its clinical application in the repair of head and neck defects. Methods The origin, course, branch, distribution, diameter, pedicle length and neighbours of superficial inferior epigastric artery and vein were dissected and measured in 10 adult corpses perfused with red latex through artery system. Results In our series of 20 cadaveric dissections, the SIEA was identified in 18(90%) and the SIEV in 20(100%). The external diameter of SIEA was 1.48±0.44mm(0.85~2.43）, The length of SIEA was 4.8±1.18 cm (2.56~7.02), averagely. The external diameter of SIEV ranged from 1.46 to 4.05mm, with the average value of 2.33±0.71mm. The length of SIEV ranged from 4.03 to 8.42cm, with the average value of 5.45±1.2cm. For those with absence or hypogenesis of SIEA, the longer and larger ascending branches of the superficial circumflex iliac artery system could be identified. Conclusions Considering its reliable blood supply, sufficient transfer area, and the slight donor site damage, the superficial inferior epigastric artery flap can be applied to reconstruct head and neck defects.
