Persistent sciatic artery (PSA) is a rare embryological vascular anomaly with a prevalence between 0.025-0.06%. PSA is frequently associated with aneurysmal degeneration and can result in neuropathy, thrombosis, or rupture, threatening limb and life.
We present a case of a 72-year-old man with an incidental finding of a right sided 4 cm PSA aneurysm with limited symptoms. The aneurysm was treated successfully with endovascular exclusion and a femoral-popliteal bypass was performed to revascularize the leg.
Treatment of PSA aneurysms involve excluding the aneurysm and revascularizing the involved leg. Improvements in endovascular embolization techniques now offer new solutions in the management of these aneurysms.
A high degree of clinical suspicion is required to properly diagnose and treat PSA aneurysms. Referral to a center with expertise in both open and endovascular techniques is vital to ensure good outcomes.
持续性坐骨动脉（PSA）是一种罕见的胚胎血管异常，患病率在0.025%至0.06%之间。PSA常与动脉瘤退变相关，可导致神经病变、血栓形成或破裂，威胁肢体和生命。
我们报告一例72岁男性，偶然发现右侧4厘米的PSA动脉瘤，症状有限。该动脉瘤通过血管内隔绝术成功治疗，并进行了股腘动脉旁路移植术以使腿部血管再通。
PSA动脉瘤的治疗包括隔绝动脉瘤和使受累腿部血管再通。血管内栓塞技术的改进为这些动脉瘤的管理提供了新的解决方案。
正确诊断和治疗PSA动脉瘤需要高度的临床怀疑。转诊至具备开放和血管内技术专业知识的中心对于确保良好预后至关重要。
