To evaluate the sartorius muscle as an alternative donor site for functional transfer, the neurovascular anatomy of the muscle was studied in 42 human sartorius muscle specimens (22 fresh and 20 preserved). Eleven adult fresh cadavers were injected with a mixture of lead oxide, gelatin and water (200 ml/kg) through the common carotid and femoral arteries. The sartorius muscle with its neurovascular pedicles was dissected, and radiographed. The sartorius muscle was also dissected out in 10 preserved cadavers. The neurovascular anatomy was thus analyzed in 42 sartorius muscles. The results show that each nerve supplying the sartorius muscle is accompanied by one vascular pedicle, forming a neurovascular hilum. Within the muscle, most of the nerves and vessels divide early, and their branches run parallel to each other and to the muscle fibers. Many of the vessels anastomose with each other to form an intricate vascular network. We conclude that it is possible to subdivide the muscle into functional units to harvest a segmental muscle flap with a neurovascular pedicle for transfer.
为评估缝匠肌作为功能转移替代供区的可行性，对42例人缝匠肌标本（22例新鲜标本和20例保存标本）的神经血管解剖结构进行了研究。对11具成年新鲜尸体通过颈总动脉和股动脉注射氧化铅、明胶和水的混合物（200 ml/kg）。将带有神经血管蒂的缝匠肌进行解剖并拍摄X线片。还在10具保存的尸体中解剖出缝匠肌。由此对42块缝匠肌的神经血管解剖结构进行了分析。结果显示，支配缝匠肌的每条神经均伴有一个血管蒂，形成一个神经血管门。在肌肉内部，大多数神经和血管早期分支，其分支相互平行且与肌纤维平行。许多血管相互吻合形成复杂的血管网络。我们得出结论，有可能将该肌肉细分为功能单位，以获取带神经血管蒂的节段性肌瓣用于转移。
