Abstract:
Posterior circulation ischemic stroke (PCIS) is caused by the infarction of the blood supply area of vertebrobasilar artery system, accounting for about 20% of all ischemic strokes. The clinical manifestations of PCIS are different and usually lack specificity. The commonly used pre-hospital stroke scale can not fully reflect signs and symptoms of PCIS, and even imaging examination is not easy to detect PCIS. As a result, it is difficult to correctly identify PCIS in the early stage in emergency settings, and the rates of misdiagnosis and missed diagnosis are significantly higher than those of the anterior circulation ischemic stroke. Early and correct identification of PCIS is of great significance to improve the prognosis of patients. By summarizing the relevant literature at home and abroad, this article discusses the diagnostic error factors of PCIS in emergency room from different angles, and summarizes the strategies and methods to improve the speed and accuracy of PCIS recognition and early management.
