Free anterolateral thigh (ALT) flap finds its place in the front row among the soft-tissue flaps used for complex reconstruction of various defects. Its versatile tissue component and ease of harvesting with minimal donor site morbidity made it a popular flap. However, its variable vascular anatomy alerts the reconstructive surgeon to remain aware of the common variation and vigilant with regard to unusual variation. Commonly described variations are about the origin and course of pedicle and perforators. There are rare reports regarding the presence of double arteries and single vein in the flap pedicle. Here, the authors describe these unusual anatomical variations in the pedicle of ALT flap, with two arteries and one vein, and discuss the surgical implication of the same.
游离股前外侧（ALT）皮瓣在用于各种缺损复杂重建的软组织皮瓣中占据前排位置。其多样的组织成分以及易于切取且供区并发症极少，使其成为一种常用皮瓣。然而，其血管解剖结构多变，这提醒重建外科医生要熟知常见变异，并对不寻常变异保持警惕。常见的变异涉及蒂部和穿支的起源及走行。关于皮瓣蒂部存在双动脉和单静脉的报道较为罕见。在此，作者描述了ALT皮瓣蒂部这种有两条动脉和一条静脉的不寻常解剖变异，并讨论了其手术意义。
