椎动脉夹层所致脊髓梗死

Spinal Cord Infarction Caused by Vertebral Artery Dissection

椎动脉夹层是青中年椎基底动脉系统缺血性卒中的常见病因之一,发病率随着影像学技术的发展呈上升趋势。椎动脉夹层的临床表现多种多样,通常以小脑、脑干缺血症状伴颈痛起病,缺血性脊髓病不是常见的临床表现。椎动脉夹层所致脊髓梗死临床上有时较难识别,可能错过发病早期的最佳治疗时机,从而造成严重后果。因此了解椎动脉夹层所致脊髓梗死的解剖学基础、临床表现、诊断、治疗及转归等对于椎动脉夹层的诊断治疗具有非常重要的意义。

Vertebral artery dissection is one of the common causes of vertebrobasilar transient ischemic stroke,particu- larly among young patients. The incidence rises with the development of imaging technology. The clinical manifestations of vertebral artery dissection are varied, which usually presents with neck pain associated with ischemic symptoms of cerebellar and brain stem,while transient spinal ischemia is not a common clinical manifestation. Spinal cord infarction caused by ver- tebral artery dissection, is sometimes difficult to identify, which may result in missing the best treatment time during the early period and causing serious outcomes. Therefore, understanding the anatomical basis, clinical manifestation, diagnosis, treatment and outcomes of vertebral artery dissection is very important for the diagnosis and treatment.
