An MR arteriogram obtained in a patient with migraine headaches during prodrome showed features of carotid dissection. A repeated study conducted within minutes demonstrated complete patency. Vascular spasm was proposed to be the cause. Migraine occurs in more than 10% of the population. The possibility of misdiagnosing a vascular spasm as carotid dissection is real and should be guarded against since there are great prognostic and treatment implications.
一名偏头痛患者在先兆期进行的磁共振血管造影显示有颈动脉夹层的特征。几分钟内重复进行的检查显示血管完全通畅。推测血管痉挛是病因。偏头痛在超过10%的人群中发生。将血管痉挛误诊为颈动脉夹层的可能性是存在的,由于存在重大的预后和治疗意义,因此应予以警惕。
