Aneurysms of the sciatic artery are quite rare. In the literature fewer than 100 cases of gluteal aneurysms have been reported; most have arisen from the superior or inferior gluteal artery; only few cases were aneurysms of an anomalous persistent sciatic artery (6 cases diagnosed angiographically and treated). In our own experience, the overall incidence of this anomaly, in patients undergoing angiography is very low, in the order of 0.025%. In our case the iliac femoral axis showed hypoplasia and required an internal iliac-popliteal bypass. For the location and the propensity atherosclerotic involvement of the persistent sciatic artery, an aneurysm should be considered in all patients with a pulsatile posterior thigh mass, with or not symptoms of peripheral vascular disease.
坐骨动脉瘤相当罕见。文献中报道的臀动脉瘤病例不足100例；大多数起源于臀上动脉或臀下动脉；只有少数病例是异常持续坐骨动脉的动脉瘤（6例经血管造影诊断并治疗）。根据我们自己的经验，在接受血管造影的患者中，这种异常的总体发生率非常低，约为0.025%。在我们的病例中，髂股轴发育不全，需要进行髂内-腘动脉搭桥术。鉴于持续坐骨动脉的位置和动脉粥样硬化累及的倾向，对于所有有大腿后部搏动性肿块的患者，无论有无周围血管疾病症状，都应考虑动脉瘤的可能。
