摘　　要：目的探讨大脑中动脉CT高密度征在急性脑梗死中临床意义。方法选取2016年1月-2016年5月于沈阳军区总医院神经内科收治的386例急性脑梗死患者的影像学及临床资料并进行回顾性研究。结果根据首次CT中是否出现大脑中动脉高密度征(HMCAS)进行分组,两组前循环皮质梗死、基底节梗死、大面积脑梗死及放射冠梗塞中梗死构成比比较,差异有统计学意义(P<0.05),两组后循环梗死(包括脑干、丘脑及枕叶皮质等)比较,差异无统计学意义(P>0.05)。结论 HMCAS常见于前循环、基底节及放射冠梗死,在大面积脑梗死中HMCAS构成比较高。Objective To explore the clinical significance of the hyperdense middle cerebral artery sign on CT scan(HMCAS)in acute cerebral infarction.Methods The clinical and imaging data of386patients diagnosed as acute cerebral infarction in the Department of Neurology of our hospital were retrospectively analyzed.Results The recruited cases were divided into two groups according to whether the HMCAS appeared in the first CT examination,there were125cases in the HMCAS group(32.4%)and261cases in the no-HMCAS group(67.6%).The constituent ratios of anterior circulation cortex infarction,basal ganglia region infarction and corona radiata infarction were statistically different between the HMCAS group and the non-HMCAS group(P<0.05).But there was no statistical difference in posterior circulation infarction(including brainstem,thalamus and occipital cortex)between the two groups(P>0.05).Conclusions HMCAS occurs primarily in anterior circulation cortex,basal ganglia region and corona radiata infarction,and its constituent ratio is high in large area cerebral infarction.
