摘要
目的:为髂腹股沟神经皮支及其营养血管为蒂岛状皮瓣的临床应用提供解剖学基础。方法:在27侧经红色乳胶液灌注的会阴及下肢标本上解剖观测髂腹股沟神经皮支及其营养血管的来源、走行、分布、吻合及外径,2侧成人新鲜标本灌注墨汁,观测营养血管的墨染范围。结果:髂腹股沟神经来源于第1腰神经腹侧支,其皮支从腹股沟管浅环穿深筋膜,穿出点横径为(1.89±0.47)mm,穿出时位于精索或子宫圆韧带下方。髂腹股沟神经皮支营养血管主要来源于阴部外浅动脉的升支、降支及股内侧支,并沿途发出皮支营养周围皮肤。结论:可以设计以髂腹股沟神经营养血管为蒂的岛状皮瓣。
Objective: To provide anatomic basis for the clinical application of island flap pedicled with the cutaneous branch of ilioinguinal nerve and its nutrient vessels. Methods:The origin, course, distribution, anastomosis and outside diameter of cutaneous branch of ilioinguinal nerve and its nutrient vessels were observed on 27 sides adult perineum and lower extremity specimens perfused with red latex .The blood supply range of nutrient vessels was observed on 2 sides fresh specimens injected with black ink. Results: Ilioinguinal nerve originated from the 1st lumbar ventral rami. Its cutaneous branch perforated deep fascia through superficial inguinal ring with an external diameter of 1.89±0.47 mm under spermatic cord or round ligament of uterus .The nutrient vessels of its cutaneous branch originated from ascending branch, descending branch and femoral medial branch of superficial external pudendal artery and sent many cutaneous arterioles to nourish the surrounding skin. Conclusions: The island flap could be designed with the cutaneous branch of ilioinguinal nerve and its nutrient vessels as its pedicles.
