摘　　要：目的为形成带感觉神经的脐旁游离皮瓣提供解剖学基础。方法在２０具４０侧成人躯干标本上，观测了下位肋间神经外侧前支与腹壁下血管形态、分支及分布规律。结果腹壁下动脉起点外径为（２．３±０．３）ｍｍ，伴行静脉（３．６±０．４）ｍｍ。下位肋间神经外侧前支在腋前线前后１～２ｃｍ相应肋间穿出，神经在锁骨中线附近浅出皮下。第８～１０肋间神经外侧前支浅出皮下在脐上０～７ｃｍ范围内，恰好支配脐旁皮瓣设计的范围。结论可设计以腹壁下血管带第８～１０肋间神经外侧前支的脐旁感觉皮瓣。Objective To provide the anatomical basis for the free paraumbilical flap with sensory nerve.Methods The morphology, branch and distribution of the inferior epigastric artery and inferior intercostal nerve were dissected and measured in 20 adult cadaver specimens.Results The diameter of inferior epigastric artery at the original point was (2.3±0.3) mm, and that of its companing vein was (3.6±0.4) mm. The anterial branch of inferior intercostal nerves transversed through their corresponding intercostal spaces of axilla anterior line and ran out of the superficial fascia at the midclavicular line. The lateral anterior branch of the eighth to tenth intercostal nerves ran out of superficial fascia in the range of 0-7 cm above umbillicus and innervated the paraumbillical flap.Conclusion It is possible to design sensory paraumbilical flap with the lateral anterior branch of the eighth to tenth intercostal nerve.
