股前及股外侧区皮神经营养血管皮瓣的应用解剖

目的：为股前及股外侧区皮神经营养血管皮瓣提供解剖学基础。方法：对20侧成人下肢标本铅丹乳胶液动脉灌注，运用各种方法观察股前及股外侧区皮神经营养血管的分支分布，分析以皮神经及其营养血管为蒂形成感觉皮瓣的可行性。结果：股外侧皮神经，股中间皮神经，股内侧皮神经解剖恒定，有内外两套血管系统，与皮下诸层次血管网互相沟通，构成股部皮神经营养血管皮瓣的解剖学基础。结论：股前及股外侧区皮神经营养血管皮瓣血供可靠，可设计不同形式的岛状皮瓣对会阴部组织器官缺损进行感觉性修复重建。

Anatomic study and clinical value of anterior and lateral thigh neurocutaneous vascular flap

Objective: To observe the blood vessel distribution of the cutaneous nerve and its adjacent flap in anterior and lateral thigh and to illustrate the anatomical basis of the survive of the neurocutaneous vascular flap. Methods: Twenty sides of cadaveric lower extremities were perfused with latex-lead oxide. The origins; courses, branches, distributions of the nutrient vessels of the anterior and lateral thigh cutaneous nerve (ATCN) and the relationship between these vessels and adjacent flap were studied. The clinical feasibility of the ATCN flap was discussed. Results: The anatomical courses of the ATCN were stable. There were two vascular network systems around the cutaneous nerves. There was well-developed anastomosis vascular network between the blood vessels of the cutaneous nerve and its adjacent flap. This was the survival basis of the ATCN flap. Conclusions: The anterior and lateral thigh neurocutaneous vascular flap could be designed to island flap in different patterns and used to repair soft-tissue and organ defects of perineum.
