Aneurysms of the extracranial carotid artery are most commonly caused by atherosclerosis or trauma but may also have unusual causes, such as Marfan's syndrome. Although aneurysmal changes in the extracranial carotid vessels usually are due to extension of aortic dissection into the carotid system, isolated aneurysms may occasionally complicate Marfan's syndrome. The authors report a case of Marfan's syndrome in which the patient, a 45-year-old woman, presented with an asymptomatic mass in the right side of the neck at the level of the carotid bifurcation. An isolated internal carotid artery aneurysm was identified. The aneurysm was resected using an interposition vein graft over an outlying shunt. Histologic examination confirmed the typical cystic medial necrosis with loss of elastic fibres and an increase of mucoid material in the media. The patient's recovery was smooth and at 2-year follow-up there were no signs of recurrent aneurysm formation.
颅外颈动脉动脉瘤最常见的病因是动脉粥样硬化或外伤，但也可能有一些不寻常的病因，如马方综合征。虽然颅外颈动脉血管的动脉瘤样改变通常是由于主动脉夹层延伸至颈动脉系统所致，但孤立性动脉瘤偶尔也可并发于马方综合征。作者报告了一例马方综合征病例，患者为一名45岁女性，在颈动脉分叉水平右侧颈部出现无症状肿块。发现了一个孤立的颈内动脉瘤。通过在外围分流管上使用间置静脉移植物切除了动脉瘤。组织学检查证实了典型的囊性中层坏死，弹性纤维丧失，中层黏液样物质增加。患者恢复顺利，随访2年无动脉瘤复发迹象。
