Rare vascular anomaly, the persistent sciatic artery (PSA) has an extremely low incidence, likely 0.04%-0.06%. This vessel is prone to thrombosis, distal thromboembolization, rupture, and aneurysmal formation, while its symptoms can vary considerably, from completely asymptomatic pictures to cases with pain, claudication or ischemia of the lower limbs. It is essential to diagnose this anomaly in time, in order to avoid dangerous complications for the patient's life. The main methods of diagnosis are given by vascular ultrasound, CT, or MRI. Here we present a case of a bilateral PSA diagnosed in a 77-year-old woman as an incidental finding in angio-CT of the lower limbs.
罕见的血管异常——坐骨动脉持续存在（PSA）发病率极低，可能为0.04% - 0.06%。该血管易于发生血栓形成、远端血栓栓塞、破裂和动脉瘤形成，其症状差异很大，从完全无症状到出现下肢疼痛、间歇性跛行或缺血等情况。及时诊断这种异常对于避免危及患者生命的危险并发症至关重要。主要诊断方法包括血管超声、CT或MRI。在此，我们报告一例77岁女性双侧PSA的病例，该病例是在下肢血管CT检查中偶然发现的。
