颈动脉夹层病因学研究进展

Research Progress on Etiology of Cervical Artery Dissections

颈动脉夹层的病理改变是动脉血流通过破损的血管内膜进入血管壁,造成血管内膜及中层分离。动脉夹层造成血管管腔狭窄或闭塞,是引起缺血性卒中的重要原因。高血压、高同型半胱氨酸血症、埃勒斯-当洛综合征、马方综合征、创伤等病因可引起颈动脉夹层,现就其病因学进行综述。

The pathological changes of cervical artery dissection（CAD） is that arterial blood enter into the vessel wall through impaired intima, resulting in artery dissection between the tunica intima and tunica media. Stenosis or occlusion of vascular lumen caused by artery dissection is the main reason for ischemic stroke. Hypertension, High homocysteine, Ehlers-Danlos syndrome, Marfan syndrome and trauma can lead to cervical artery dissection. The etiology were reviewed in this article.
