Arterial dissection is the result of blood entering along the intima-media plane through a breach produced either spontaneously or traumatically. Cervical arterial dissections are an important cause of acute ischemic stroke in children, young adults, and patients with cranio-cervical traumatic injuries. Arterial dissections occur either spontaneously, in genetic diseases, the most important association being with fibromuscular dysplasia. In most of the cases dissection involve the extracranial portions of the internal carotid and vertebral arteries. Magnetic resonance with T1 fat-saturation (T1 FS) sequence of the cervical region or computed tomography (CT) with computed tomography angiography (CTA) shows a very high sensitivity and specificity in the diagnosis of cervical artery dissections. Therapeutic options are still debatable in patients with acute ischemic stroke and vertebral or carotid artery dissection.
动脉夹层是血液通过自发或外伤造成的内膜-中膜平面破裂进入该区域的结果。颈动脉夹层是儿童、年轻成年人以及颅颈外伤患者急性缺血性卒中的重要病因。动脉夹层可自发发生于遗传性疾病，其中最重要的关联是与纤维肌发育异常有关。在大多数情况下，夹层累及颈内动脉和椎动脉的颅外部分。颈部区域的T1脂肪饱和（T1 FS）序列磁共振成像或计算机断层扫描血管造影（CTA）的计算机断层扫描（CT）在诊断颈动脉夹层方面显示出非常高的敏感性和特异性。对于急性缺血性卒中和椎动脉或颈动脉夹层患者，治疗选择仍存在争议。
