颈部动脉夹层病因及危险因素

Etiology and risk factors of cerebral artery dissections

颈部动脉夹层是中青年卒中的重要原因。颈部动脉夹层分外伤性和自发性,后者的发病机制还不清楚,与许多因素相关,如遗传因素、全身性动脉病、血管异常、高血压、偏头痛以及颈部轻微外伤、医源性原因、近期感染。早期识别这些危险因素对于颈部动脉夹层的预防、诊断、治疗以及缺血性卒中的防治非常重要。

Carotid artery dissection is a major cause of stroke, especially in young and middle-aged patients. A dissection is thought to result from trauma or can occur spontaneously. Many risk factors have been identified in association with carotid artery dissection such as hereditary factors, systemic arteriopathy, vascular anomaly, hypertension, migraine, trivial neck trauma, cervical spine manipulation and recent infection. Early recognition of these risk factors is favorable to prevention, diagnosis and management of the dissection.
