磁共振血管造影诊断脑梗死患者颅内动脉硬化程度的探讨

目的探讨磁共振血管造影诊断脑梗死患者颅内动脉硬化程度的意义。方法选择47例脑梗死患者,根据梗死面积不同分为〉1.5cm2者26例,〈1.5cm2者21例,总结磁共振血管造影诊断与脑梗死患者动脉硬化程度及梗死面积之间的关系。结果梗死面积〈1.5cm2者发生轻度动脉硬化的比例大于梗死面积〉1.5cm2者（P〈0.05）,发生重度动脉硬化比例低于梗死面积〉1.5cm2者（P〈0.05）,血管正常比例高于梗死面积〉1.5cm2者（P〈0.05）,检出动脉闭塞比例低于梗死面积〉1.5cm2者（P〈0.05）。结论磁共振血管造影提高了患者的舒适度,尤其是对于意识障碍及年老体弱呼吸功能较差患者,通过动脉闭塞情况可以反映动脉硬化程度,具有重要的临床应用价值。

Discussion of magnetic resonance angiography in the diagnosis of the extent of intracranial arteriosclerosis to the cerebral infarction patients

Objective To discuss the significance of magnetic resonance angiography in the diagnosis of the extent of intracranial arteriosclerosis to the cerebral infarction patients. Methods 47 cases of cerebral infarction pitients were according to the area of infarction were divided into two groups, the greater than 1.5 cm2 group with 26 cases and less than 1.5 cm 2 with 21 cases, then the relationship between magnetic resonance angiography in the diagnosis and the extent of atherosclerosis and cerebral infarction infarction area were summarized. Results The proportion of mild atherosclerosis occured in patients with cerebral infarction area less than 1.5 cm2 was greater than the patients whose cerebral infarction area greater than 1.5 cm 2 （P 0.05）, and the severe arteriosclerosis ratio was lower than the patients whose infarct size greater than 1.5 cm 2 （P 0.05）, the proportion of normal blood vessels was higher than the patients whose infarct size greater than 1.5 cm 2 （P 0.05）, the detection of occlusion ratio was lower than the patients whose infarct size greater than 1.5 cm 2 （P 0.05）. Conclusion Magnetic resonance angiography can improve the patients＇ comfort,especially for the disturbance of consciousness and the frail elderly patients with poor respiratory function, through the checking of artery occlusion can reflect the degree of atherosclerosis,so it has important clinical application value.
