A persistent sciatic artery (PSA) is a rare vascular anomaly not extensively described in the interventional cardiology literature. Because of its vulnerable position, it is associated with a high risk of aneurysm formation, making it prone to thrombus formation with subsequent arterial insufficiency because of distal embolization. We report the case of an 80-year-old woman who was found to have bilateral PSA with unilateral aneurysm and evidence of possible distal embolization on conventional angiography.
持续性坐骨动脉（PSA）是一种罕见的血管异常，介入心脏病学文献中对此描述不多。由于其位置易受影响，它与动脉瘤形成的高风险相关，容易形成血栓，随后因远端栓塞导致动脉供血不足。我们报告了一例80岁女性病例，该患者被发现双侧患有PSA，一侧有动脉瘤，传统血管造影显示可能存在远端栓塞迹象。
