The presence of any pulsatile mass suggests an underlying aneurysm. When such masses occur in the buttock, the differential diagnosis includes aneurysms arising from branches of gluteal vessels or aneurysms developing in a persistent sciatic artery (PSA). The investigation and management of two patients with pulsatile masses are described. Review of the embryologic aspects of these masses and the important literature on the subject led to the conclusions that when a pulsatile buttock mass is encountered, an anomalous PSA should be suspected. A gluteal artery aneurysm can be treated by ligation or occlusion, but for a sciatic artery aneurysm surgical ablation is necessary and distal perfusion must be achieved postoperatively.
任何搏动性肿块的出现提示可能存在潜在的动脉瘤。当此类肿块出现在臀部时，鉴别诊断包括臀血管分支处的动脉瘤或持续坐骨动脉（PSA）形成的动脉瘤。本文描述了两名搏动性肿块患者的检查和治疗情况。回顾这些肿块的胚胎学方面以及关于该主题的重要文献后得出结论，当遇到搏动性臀部肿块时，应怀疑存在异常的PSA。臀动脉动脉瘤可通过结扎或闭塞治疗，但对于坐骨动脉动脉瘤，手术切除是必要的，且术后必须实现远端灌注。
