Abstract
Objective To investigate whether there are differences in characteristics of intracranial atherosclerotic plaque of different mechanisms of patients with intracranial atherosclerotic stroke. <br> Methods Patients who were diagnosed with symptomatic intracranial atherosclerotic stenosis (sICAS) according to Chinese Ischemic Stroke Subclassification (CISS) criteria were recruited consecutively as study subject into this study. Patients whose diagnosis was asymptomatic intracranial atherosclerotic disease were enrolled as control group. All subjects underwent 3-T high-resolution magnetic resonance imaging (HR MRI) in the relevant intracranial artery. The characteristics of intracranial atherosclerotic plaque in different mechanisms of intracranial atherosclerotic stroke were compared. <br> Results Finally, 56 sICAS patients and non-symptomatic ICAS patients were enrolled into study. Compared with non-symptomatic ICAS patients, the manifestation of characteristics of intracranial atherosclerotic plaque of sICAS patients including high rate of outward remodeling of the stenotic area and low rate of inward remodeling of the stenotic area, and the plaques of the symptomatic group were more frequently located close to perforator arterial openings. There was no signiifcant difference in the characteristics of intracranial atherosclerotic plaque in different mechanisms of intracranial atherosclerotic stroke. HR MRI found atherosclerotic plaque in 10 patients who hadn’t been identiifed with intracranial artery stenosis by transcranial Doppler (TCD) and magnetic resonance angiography (MRA). <br> Conclusion HR MRI is helpful in discovering the existence of atherosclerotic plaques in sICAS patients, however, there is no significant difference in HR MRI characteristic of intracranial atherosclerotic plaque of different mechanisms of sICAS.关键词
