Persistent sciatic artery is a rare anomaly, only 33 cases having been reported to date. A 34th case is described in this report., The patient, a 45-year-old man, had bilaterally persistent sciatic arteries with bilateral aneurysms and acute ischemia due to distal embolization. The literature regarding the embryology, incidence and the problems of diagnosis and management of this rare condition is reviewed. The authors emphasize that in cases of aneurysm formation if the sciatic nerve adheres to the aneurysm no attempt should be made to excise the aneurysmal sac.
永存坐骨动脉是一种罕见的异常情况，迄今为止仅报道过33例。本报告描述了第34例病例。患者为一名45岁男性，双侧存在永存坐骨动脉，并伴有双侧动脉瘤以及因远端栓塞导致的急性缺血。本文回顾了有关这种罕见病症的胚胎学、发病率以及诊断和处理问题的文献。作者强调，在动脉瘤形成的病例中，如果坐骨神经附着于动脉瘤，则不应试图切除动脉瘤囊。
