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

The Clinical and MRI Differential Expression of Patients with Acute Cerebral Infarction Caused by Moderate to Severe Middle Cerebral Artery Stenosis

目的:探讨分析中度与重度大脑中动脉狭窄所导致的急性脑梗死患者的临床和磁共振差异性表现。方法:回顾性分析笔者所在医院急性脑梗死患者的临床资料,按照大脑中动脉狭窄程度分为中度狭窄(A组)和重度狭窄(B组),对其临床和磁共振差异进行总结。结果:中度大脑中动脉狭窄导致急性脑梗死年龄>60岁的患者少于重度大脑中动脉狭窄导致急性脑梗死的患者,且差异有统计学意义(P<0.05);从临床角度上看,中度大脑中动脉狭窄更容易导致腔隙性梗死,从磁共振影像学的角度看深部小梗死为其主要梗死类型,重度大脑中动脉狭窄更容易导致部分前循环梗死及皮层区域梗死,且两组比较差异有统计学意义(P<0.05)。结论:大脑中动脉狭窄程度与年龄、梗死类型都是有关的,能引起显著的临床与磁共振差异。

Objective： To investigate and analyze the clinical and MRI differential expression of patients with acute cerebral infarction caused by Moderate to severe middle cerebral artery stenosis.netbod： A retrospective analysis in clinical data of acute cerebral infarction patients in author＇s hospital was done, all patients were divided into moderate stenosis （group A） and severe stenosis （group B） in accordance with the degree of middle cerebral artery stenosis, differences in the clinical and magnetic resonance were summarized.Result： Moderate middle cerebral artery stenosis leading to acute cerebral infarction patients who were older than 60 years were less than the number of patients with acute cerebral infarction caused by severe middle cerebral artery stenosis, and the difference was statistically significance（P〈0.05）; From a clinical point of view, moderate middle cerebral artery stenosis was more likely to lead to lacunar infarction, from MRI point of view, the deep small infarction as its main types, severe middle cerebral artery stenosis was more likely to cause partial anterior circulation infarction and cortex infarction, and there was significant difference between two groups（P〈0.05）.Conclusion： The degree of middle cerebral artery stenosis and age, infarct types are related, and can cause significant differences in clinical and MRI.
