Persistent sciatic artery (PSA) aneurysms are rare vascular anomalies that can lead to significant clinical complications. This case report details the diagnosis, initial management, and long-term follow-up of a 66-year-old female patient who presented with progressive right gluteal pain. Diagnostic imaging at the initial hospital visit identified a 6.5 cm saccular aneurysm in the right sciatic artery. The patient underwent endovascular repair using a Vascutek Anaconda stent graft limb (Terumo, Florida, USA) via a femoral access. Four years later, a recurrence of the aneurysm was detected at the distal end of the stent graft, measuring 3.5 cm. Endovascular treatment, including stent extension, was successfully performed. The patient was discharged in stable condition with a recommendation for 6-month follow-up imaging. This case underscores the importance of advanced imaging for accurate diagnosis and the efficacy of endovascular techniques in managing PSA aneurysms. The recurrence highlights the need for ongoing surveillance and tailored interventions. This case contributes to the limited literature on PSA aneurysms and offers insights into effective management strategies. It emphasizes that persistent sciatic artery aneurysms require a multidisciplinary approach and careful long-term follow-up, with endovascular techniques, combined with cross-sectional imaging, providing effective management that improves patient outcomes.
持续性坐骨动脉（PSA）动脉瘤是一种罕见的血管异常，可导致严重的临床并发症。本病例报告详细介绍了一名66岁女性患者的诊断、初始治疗及长期随访情况，该患者因进行性右臀疼痛就诊。初次就诊时的诊断性影像学检查发现右侧坐骨动脉有一个6.5厘米的囊状动脉瘤。患者通过股动脉入路使用Vascutek Anaconda支架移植物肢体（美国佛罗里达州泰尔茂公司）进行了血管内修复。四年后，在支架移植物远端检测到动脉瘤复发，大小为3.5厘米。成功进行了包括支架延伸在内的血管内治疗。患者出院时情况稳定，并建议进行6个月的随访影像学检查。本病例强调了先进影像学检查对准确诊断的重要性以及血管内技术在治疗PSA动脉瘤方面的有效性。复发情况凸显了持续监测和针对性干预的必要性。本病例丰富了关于PSA动脉瘤的有限文献，并为有效管理策略提供了见解。它强调持续性坐骨动脉动脉瘤需要多学科方法和仔细的长期随访，血管内技术与横断面成像相结合可提供有效的治疗，改善患者预后。
