动脉夹层发生时，内膜撕裂允许血液进入动脉壁，可能损害管腔和减少血流。颈动脉和椎动脉夹层通常发生在严重创伤后，尽管它们也可以自发或在轻微损伤后发生。动脉夹层与多种因素相关，包括高血压、纤维肌性发育不良、马凡氏综合征、囊性中膜坏死、口服避孕药、药物滥用（拟交感神经药）和感染[1-8]。重要的是要及早识别动脉夹层，以便及时开始治疗，以防止缺血性并发症[1]。在这篇文章中，我们阐述了使用磁共振血管造影在诊断颈动脉和椎动脉夹层。
Arterial dissection occurs when an intimal tear allows blood to enter the arterial wall, potentially compromising the lumen and reducing blood flow. Carotid and vertebral artery dissections typically occur after major trauma, although they also can arise spontaneously or after trivial injury. Arterial dissection has been associated with a variety of factors, including hypertension, fibromuscular dysplasia, Marfan syndrome, cystic medial necrosis, oral contraceptives, drug abuse (sympathomimetics), and infection [1-8]. It is important to recognize arterial dissection early so that prompt treatment can be initiated to prevent ischemic complications [1]. In this essay, we illustrate the use of MR angiography in the diagnosis of carotid and vertebral artery dissection.
