摘要
过去研究认为缺血性脑卒中责任血管为梗死区域对应的狭窄血管,尤其是当颅内血管狭窄>50%可能会引起脑卒中发作.但是越来越多的研究发现磁共振血管成像(magnetic resonance angiography,MRA)上无明显狭窄的脑卒中患者在颅内动脉MR管壁成像检查时发现与之对应的动脉粥样硬化斑块.因此,笔者认为斑块的易损性可能是引起缺血性脑卒中发病的主要原因.颅内动脉MR管壁成像能够清晰地显示颅内大血管的管壁情况.所以笔者对缺血性脑卒中责任血管的管壁特征以及如何量化责任血管内易损斑块进行综述.
Previous studies have suggested that the responsible vessels for ischemic stroke are the narrow vessels corresponding to the infarcted area,especially when intracranial vessel stenosis>50%may cause a stroke.However,more and more studies have found that patients with stroke without obvious stenosis on the MRA have found corresponding atherosclerotic plaques on the MR wall imaging of the intracranial artery.Therefore,we believe that the vulnerability of plaque may be the main cause of ischemic stroke.MR wall imaging of intracranial arteries can clearly show the wall conditions of intracranial vessels.Therefore,this article reviews the characteristics of the vessel wall of the responsible vessels in ischemic stroke and how to quantify the vulnerable plaques in the responsible vessels.
