A superficial ulnar artery identified during the elevation of a free forearm flap is reported. This is the second case appearing in the English literature. The free forearm flap is increasingly popular among plastic surgeons, and it is therefore imperative that this anomaly be well recognized because inadvertent injury of this anomalous artery may devascularize the hand. In cadaver dissections, the incidence of this anomaly has been reported to be 3.1%. This variation is probably encountered in clinical practice more commonly, but it is not recognized. Identification of this anomalous artery is facilitated by elevating but not exsanguinating the forearm prior to harvesting the flap.
本文报道了在游离前臂皮瓣掀起过程中发现的一条尺侧浅动脉。这是英文文献中出现的第二例。游离前臂皮瓣在整形外科医生中越来越受欢迎，因此必须充分认识到这种异常情况，因为意外损伤这条异常动脉可能会导致手部缺血。在尸体解剖中，这种异常情况的发生率据报道为3.1%。在临床实践中可能更常见到这种变异，但未被识别。在切取皮瓣前通过抬起前臂但不驱血来有助于识别这条异常动脉。
