The gracilis muscle is widely used in reconstructive surgery, either as a pedicled flap or as a free microsurgical flap. The aim of this study was to demonstrate in detail the arterial anatomy of the gracilis muscle, particularly its intramuscular artery distribution, by using a method involving red latex injection and glycerin transparency, which makes muscle tissues quite transparent and allows direct visualization of the arterial anatomy. Twenty-four specimens of gracilis muscle were harvested after injecting 12 cadavers with red latex. The different patterns of blood supply of the gracilis muscle were counted. A complete arterial system formed by anastomoses of intramuscular arterial branches was observed in each specimen. The existence of several arterial branches at the proximal origin of each muscle was observed. The results of this study provide reconstructive surgeons with useful information regarding gracilis muscle flap design.
内收肌在重建外科中应用广泛，既可以作为带蒂皮瓣，也可以作为游离的显微外科皮瓣。本研究旨在通过使用红色乳胶注射和甘油透明化的方法，详细展示内收肌的动脉解剖结构，特别是其肌内动脉分布，该方法使肌肉组织非常透明，可以直接观察动脉解剖结构。对 12 具尸体进行红色乳胶注射后，采集了 24 个内收肌标本。统计了内收肌的不同供血模式。在每个标本中，都观察到由肌内动脉分支吻合形成的完整动脉系统。还观察到每个肌肉近端起点处有几个动脉分支。本研究结果为重建外科医生提供了有关内收肌皮瓣设计的有用信息。
