【摘要】目的探讨脑梗塞患者颅内动脉硬化程度和特征,评价MRA对颅内动脉硬化诊断价值。。结果脑梗塞组颅内动脉硬化检出率高于正常组、重度颅内动脉硬化梗塞组明显高于正常组。结论颅内动脉硬化与脑梗塞有很好的相关性,是脑梗塞的主要危险因素,MRA对颅内动脉硬化分度及早期血管狭窄病变诊断具有重要的意义,可为脑梗死诊断治疗及预防提供参考资料。

[Abstract] Objective To explore the extent of intracranial atherosclerosis and characteristics of cerebral infarction patients, evaluate the value of MRA in diagnosing intracranial atherosclerosis. Methods Toshiba contrast to the MRA test results of 140 cerebral infarction patients and 156 normal patients. Results Group of intracranial cerebral atherosclerosis detection rate higher than the normal group, severe intracranial atherosclerotic infarction group was significantly higher than normal Group. Conclusion Intracranial atherosclerosis and cerebral infarction have good correlation, are the main risk factors for cerebral infarction,MRA has an important value in diagnosing the exten
t of intracranial atherosclerosis and early vascular stenosis , which provide references for the diagnosis and treatment and prevention of cerebral infarction .

颈外动脉粥样硬化,早在50年代就开始对它的研究[1],其与脑梗塞的关系也得到认可。众多学者认为,颈动脉粥样硬化是发生脑梗塞的原因之一[2,3]。对颅内动脉硬化严重程度进行评估,可以为缺血性脑血管病的诊断、治疗和预防提供依据。目前应用MRA对颅内动脉硬化程度进行评估未见相关报道,本课题应用磁共振血管成像(MRA)对动脉硬化程度进行评估,分析颅内动脉硬化的程度与脑梗塞关系。
