The persistent sciatic artery is a rare vascular anomaly, with only 37 reported cases in the world literature. Estimates of incidence, based on angiographic series, range from 0.04 to 0.06%. It may pose a threat to the viability of the lower extremity, for the pathologic character of the persistent sciatic artery is such that it is especially prone to atheromatous degeneration, thrombosis, distal thromboembolization, aneurysmal formation, and rupture. Although rare, the possibility of such an anomaly must be borne in mind with certain clinical presentations, during orthopedic procedures on the hip, and during angiographic studies of the leg. Successful surgical correction of the problem necessitates excluding the anomalous artery from the circulation while revascularizing the lower extremity.
坐骨动脉持续存在是一种罕见的血管异常，世界文献中仅报道了37例。根据血管造影系列研究，其发病率估计在0.04%至0.06%之间。坐骨动脉持续存在可能会对下肢的生存能力构成威胁，因为其病理特征使其特别容易发生动脉粥样硬化退变、血栓形成、远端血栓栓塞、动脉瘤形成和破裂。尽管这种异常情况罕见，但在某些临床表现、髋关节骨科手术以及腿部血管造影研究过程中，必须考虑到这种可能性。要成功地通过手术解决该问题，需要在恢复下肢血运的同时将异常动脉排除在循环之外。
