Aneurysms of the internal carotid artery (ICA) secondary to fibromuscular dysplasia (FMD) are extremely rare. We report two unique variants of extracranial ICA aneurysms due to FMD. The first patient was a hypertensive 51-year-old woman who was found to have a nontraumatic, nonmycotic saccular pseudoaneurysm of the right ICA. The second patient was a 46-year-old woman who presented with 90% stenosis and a focal dissecting aneurysm of the right ICA. Both underwent successful aneurysm resection with interposition saphenous vein grafting after anterior subluxation of the mandible. A review of the literature revealed only 21 other reported cases of aneurysms of the extracranial ICA due to FMD; all were managed successfully with surgical repair. Surgery can be performed with minimal or no morbidity, even in the distal ICA, if the exposure is adequate.
继发于纤维肌发育不良（FMD）的颈内动脉（ICA）动脉瘤极为罕见。我们报告了两例因FMD导致的颅外ICA动脉瘤的独特病例。首例患者为一名51岁的高血压女性，发现患有右侧ICA非创伤性、非霉菌性囊状假性动脉瘤。第二例患者是一名46岁女性，表现为右侧ICA 90%狭窄及局灶性夹层动脉瘤。两名患者均在下颌骨前脱位后成功进行了动脉瘤切除并置入大隐静脉移植血管。文献回顾显示，仅有另外21例因FMD导致的颅外ICA动脉瘤的报道病例；所有病例均通过手术修复成功治疗。如果暴露充分，即使在ICA远端，手术也可在极少或无并发症的情况下进行。
