The transverse rectus abdominis musculocutaneous (TRAM) flap based on the deep inferior epigastric artery is useful in head and neck reconstruction as it provides substantial skin and soft tissue cover, and allows volume to be replaced in large defects. A major advantage is the anatomical reliability of the deep inferior epigastric pedicle. We report a case in which neither rectus abdominis muscles had a blood supply from the deep inferior epigastric artery, which necessitated a change in the planned reconstruction. We review variations in the anatomical course of the artery and, although rare, stress the importance of reconstructive surgeons being aware of such variations.
基于腹壁下深动脉的腹直肌肌皮瓣（TRAM瓣）在头颈部重建中很有用，因为它能提供大量的皮肤和软组织覆盖，并可用于填充大的缺损。一个主要优点是腹壁下深蒂的解剖学可靠性。我们报告了一例病例，其中双侧腹直肌均无来自腹壁下深动脉的血供，这使得原本计划的重建方案必须改变。我们回顾了该动脉解剖走行的变异情况，尽管这种情况罕见，但强调了重建外科医生了解此类变异的重要性。
