Persistent sciatic artery is a rare developmental anomaly. In its complete form, it provides the major arterial supply to the lower leg since the femoral system is hypoplastic. These unique arteries are prone to aneurysm formation and most commonly present with complications related to aneurysm formation, which can lead to limb loss. We encountered a 68-year-old man presenting with bilateral lower-extremity ischemia who was found to have bilateral persistent sciatic artery aneurysms. One aneurysm had already thrombosed, but the other was still patent. We treated this patient with a hybrid open and endovascular repair on the patent side. The aneurysm was excluded with an Amplatzer™ plug (St. Jude Medical, Inc., St. Paul, MN) followed by a femoropopliteal bypass with saphenous vein in situ to revascularize the lower leg. To our knowledge, this is only the second report of a persistent sciatic artery aneurysm successfully treated with Amplatzer plug occlusion.
持续性坐骨动脉是一种罕见的发育异常。在其完整形式下，由于股动脉系统发育不全，它为小腿提供主要的动脉血供。这些独特的动脉易于形成动脉瘤，最常见的表现是与动脉瘤形成相关的并发症，这可能导致肢体丧失。我们遇到一名68岁男性，表现为双侧下肢缺血，经检查发现患有双侧持续性坐骨动脉动脉瘤。其中一个动脉瘤已经血栓形成，但另一个仍通畅。我们对通畅侧采用开放手术与血管腔内修复相结合的方法治疗该患者。先用Amplatzer™封堵器（圣犹达医疗公司，明尼苏达州圣保罗）封堵动脉瘤，然后行大隐静脉原位股腘动脉旁路移植术以使小腿重新血管化。据我们所知，这是第二例成功使用Amplatzer封堵器闭塞治疗持续性坐骨动脉动脉瘤的报告。
