摘要
后循环又称椎基底动脉系统,由椎动脉、基底动脉和大脑后动脉及其分支组成,主要供血给脑干、小脑、丘脑、海马、枕叶、部分颞叶及脊髓。后循环缺血是常见的缺血性脑血管病,约占缺血性卒中的20%。后循环缺血(PCI)早期症状可仅表现为孤立性眩晕,临床诊断困难,从孤立性眩晕患者中筛查出中枢性眩晕非常重要。通过归纳患者危险因素及影像学检查综合分析可提高PCI性孤立性眩晕的准确性。
The posterior circulation,also known as vertebrobasilar artery system,consists of vertebral artery,basilar artery,posterior cerebral artery and its branches,mainly supplying blood to brain stem,cerebellum,thalamus,hippocampus,occipital lobe,part of temporal lobe and spinal cord.Posterior circulation ischemia is a common ischemic cerebrovascular disease,accounting for about 20%of ischemic stroke.The early symptoms of circulatory ischemia after extraction can only be isolated vertigo,so it is difficult to make clinical diagnosis.It is very important to screen out central vertigo from patients with isolated vertigo.The accuracy of posterior circulation ischemic isolated vertigo can be improved by summarizing the risk factors and comprehensive analysis of imaging examination.
