中重度大脑中动脉狭窄所致急性脑梗死患者的临床与磁共振差异性表现分析

Analysis of different manifestation of clinical manifestation and magnetic resonance imaging in patients with acute cerebral infarction caused by middle cerebral arteriostenosis

目的:探讨中重度大脑中动脉狭窄所致急性脑梗死患者的临床与磁共振差异性表现。方法:收治急性脑梗死患者56例,均由动脉狭窄所致,根据狭窄程度,分为中度狭窄组、重度狭窄组,比较两组临床与磁共振差异性表现。结果:中度大脑中动脉狭窄诱发的急性脑梗60岁以上患者,明显少于重度狭窄组(P<0.05)。中度狭窄组易导致腔隙性梗死,磁共振表现为深部小梗死,重度狭窄组导致部分前循环梗死及皮层区域梗死,差异明显具有统计学意义(P<0.05)。结论:大脑中动脉狭窄程度与患者年龄、梗死类型存在明显的相关性,导致临床与磁共振的差异性表现。

Objective:To investigate the different manifestation between clinical manifestation and magnetic resonance imaging in patients with acute cerebral infarction caused by middle cerebral arteriostenosis.Methods:According to the degree of stenosis,56 cases of patients with acute cerebral infarction caused by arterial stenosis were divided into the moderate stenosis group and the severe stenosis group,the different manifestation of clinical manifestation and magnetic resonance imaging between the two groups were compared.Results:The number of patients over 60 years old with acute cerebral infarction caused by moderate middle cerebral arteriostenosis was significantly less than that of the severe stenosis group(P<0.05).The moderate stenosis group lead lacunar infarction easily and MRI manifestations was small deep cerebral infarcts,and the severe stenosis group lead to partial anterior circulation infarction and cortex infarction,the difference had statistical significance(P<0.05).Conclusion:The degree of middle cerebral arteriostenosis was associated with the patients age and type of cerebral infarction,which lead to the difference of clinical and magnetic resonance imaging.
