Persistent sciatic artery is a direct continuation of the internal iliac artery. It is a rare anatomic variant where the sciatic artery does not regress during fetal development. We present a case of a 43-year-old male with a right leg ulcer who has an incidental finding of persistent sciatic artery on Computed Tomography (CT) of the thigh with Intravenous (IV) contrast to evaluate for abscess formation. A major complication seen in some patients with persistent sciatic artery is aneurysm formation which predispose patients to limb-threatening thromboembolism. Asymptomatic cases such as this case require no intervention apart from follow up.
持续性坐骨动脉是髂内动脉的直接延续。它是一种罕见的解剖变异，即在胎儿发育过程中坐骨动脉不会退化。我们报告一例43岁男性患者，其右腿溃疡，在进行大腿计算机断层扫描（CT）并静脉注射（IV）造影剂以评估脓肿形成时偶然发现持续性坐骨动脉。一些持续性坐骨动脉患者中可见的主要并发症是动脉瘤形成，这使患者易发生危及肢体的血栓栓塞。像该病例这样的无症状病例，除了随访外无需干预。
