Angiographic examination in a patient with sciatic-like pain on the right side and a firm, pulsatile, non-tender mass in the right buttock revealed a large sciatic artery aneurysm. The aneurysm was successfully resected at surgery. The primitive sciatic artery is the main arterial supply to the lower extremities in the 9-mm embryo. Its persistence, while very rare, is of clinical significance because of the tendency for aneurysms to develop in the artery. Surgical resection is indicated in sciatic artery aneurysms because of the danger of rupture or embolic occlusion of arteries distal to the aneurysm.
一位右侧有坐骨神经样疼痛且右臀部有一个坚实、搏动性、无压痛肿块的患者，血管造影检查显示为一个大的坐骨动脉动脉瘤。该动脉瘤在手术中成功切除。原始坐骨动脉是9毫米胚胎下肢的主要动脉供应。它的持续存在虽然非常罕见，但具有临床意义，因为该动脉有形成动脉瘤的倾向。由于动脉瘤破裂或动脉瘤远端动脉发生栓子闭塞的危险，坐骨动脉动脉瘤需要进行手术切除。
