Abnormal persistent of the embryonic axial blood supply to the leg, the sciatic artery, is a rare but often clinically important condition. The sciatic artery may vary from a small collateral in the upper thigh to a very large vessel that is the leg's sole arterial blood supply. The abnormal artery is prone to aneurysmal dilatation and atherosclerotic occlusion, and different patterns of anatomic development in the sciatic and femoral artery systems pose significant diagnostic and therapeutic problems. Advances in preoperative hemodynamic assessment, arteriography, and vascular surgical technique have improved the results of management of persistent sciatic artery and its complications. The world literature has been reviewed, including one additional case, with emphasis on embryologic development, anatomic variations, and clinical presentation, as well as diagnosis, therapy, and results.
胚胎期供应下肢的轴性血液供应——坐骨动脉异常持续存在，是一种罕见但在临床上常具有重要意义的病症。坐骨动脉的情况各异，可从小腿上部的小分支血管到成为下肢唯一动脉血液供应的非常粗大的血管。异常动脉易于发生动脉瘤样扩张和动脉粥样硬化性闭塞，坐骨动脉和股动脉系统不同的解剖发育模式带来了重大的诊断和治疗难题。术前血流动力学评估、动脉造影和血管外科技术的进展改善了对持续存在的坐骨动脉及其并发症的治疗效果。本文对世界文献进行了综述，包括另外1例病例，重点关注胚胎发育、解剖变异、临床表现，以及诊断、治疗和结果。
