Persistent sciatic artery is a very uncommon embryologic vascular variant, with a prevalence of 0.05% based on angiographic studies. Two different types of this anomaly can occur, complete or incomplete, on the basis of the relationship between sciatic artery and femoral artery. Although many of these patients are asymptomatic, it may represent a threat to the viability of the lower extremity because of atherosclerotic degeneration resulting in aneurysmal dilatation, occlusive thrombosis, or embolic phenomena with distal complication. We present a case of a 64-year-old man with combined, complete and incomplete, type of persistent sciatic artery causing ischemic ulcer of the first toe.
永存坐骨动脉是一种非常罕见的胚胎血管变异，根据血管造影研究，其发生率为0.05%。根据坐骨动脉与股动脉之间的关系，这种异常可分为两种不同类型，即完全型或不完全型。虽然这些患者中的许多人没有症状，但由于动脉粥样硬化退变导致动脉瘤样扩张、闭塞性血栓形成或栓塞现象及远端并发症，它可能对下肢的生存能力构成威胁。我们报告一例64岁男性患者，患有混合型、完全型和不完全型永存坐骨动脉，导致第一趾缺血性溃疡。
