Persistent sciatic artery (PSA) is a rare anomaly that may cause various symptoms, such as aneurysm, rupture, thromboembolism, and sciatica. Direct surgery can be performed to treat PSA aneurysm (PSAA), but is associated with complications; e.g., anatomical problems such as sciatic nerve injury. Herein we report a case of a 74-year-old woman with acute limb ischemia that developed from a distal embolism caused by a thrombus in the left PSAA; favorable results were obtained for her by treatment with a stent-graft after rapid anticoagulation therapy for limb salvage.
持续性坐骨动脉（PSA）是一种罕见的异常情况，可能会引起各种症状，如动脉瘤、破裂、血栓栓塞和坐骨神经痛。可以通过直接手术治疗PSA动脉瘤（PSAA），但该手术会引发并发症，例如像坐骨神经损伤这样的解剖学问题。在此，我们报告一例74岁女性患者，其因左PSAA内血栓导致的远端栓塞而出现急性肢体缺血；在进行快速抗凝治疗以挽救肢体后，通过支架植入术对其进行治疗，取得了良好效果。
