First described by Green in 1832, persistent sciatic artery (PSA) is a rare anomaly classified into 2 types, namely complete and incomplete. We report the case of bilateral PSAs diagnosed by computed tomography angiography (CTA) in a 45-year-old female who presented with a 2-week history of pain and numbness in the left lower limb. Specifically, the CTA showed an incomplete PSA of the right lower limb and a complete PSA of the left lower limb complicated by an aneurysm. Complications of PSA, including aneurysmal rupture, occlusive thrombosis, and distal embolization, are critical as they impose serious hazards to the viability of the lower limbs. Asymptomatic patients with PSA require close surveillance for early detection and proper management of PSA-related complications, as they are prone to early atheromatous degeneration and aneurysm formation.
持续性坐骨动脉（PSA）于1832年由格林首次描述，是一种罕见的异常情况，分为完全型和不完全型两种类型。我们报告了一例通过计算机断层血管造影（CTA）诊断出双侧PSA的45岁女性病例，该患者有左下肢疼痛和麻木2周的病史。具体而言，CTA显示右下肢为不完全型PSA，左下肢为完全型PSA并伴有动脉瘤。PSA的并发症，包括动脉瘤破裂、闭塞性血栓形成和远端栓塞，至关重要，因为它们会对下肢的生存能力造成严重危害。无症状的PSA患者需要密切监测，以便早期发现并妥善处理与PSA相关的并发症，因为他们易于早期发生动脉粥样硬化退变和动脉瘤形成。
