The anterolateral thigh flap is a fasciocutaneous flap based on the descending branch of the lateral circumflex femoral artery. The vascular pedicle and its perforators have a varied anatomical course that has led to difficulties in flap harvest. Many papers have described the anatomical variation in the origin and path of this vessel, but they all show one artery and two accompanying venae commitantes. The authors report the first case of duplication of the descending branch of the lateral circumflex femoral artery. They discuss whether this variation requires two arterial anastomoses.
股前外侧皮瓣是一种基于旋股外侧动脉降支的筋膜皮瓣。其血管蒂及其穿支具有多变的解剖走行，这导致皮瓣切取存在困难。许多文献描述了该血管的起源和走行的解剖变异，但均显示一支动脉和两支伴行静脉。作者报告首例旋股外侧动脉降支的双重分支。他们讨论了这种变异是否需要进行两个动脉吻合。
