大脑中动脉狭窄的动态演变与其周围微小血管的关系
The Association between Dynamic Changes of MCA Stenosis and Its Surrounding Small Vessels in Brain
摘要
Abstract
Objective To analyze the relationship between the stenotic or occluded middle cerebral artery (MCA) and a newly discovered imaging phenomenon, which called small vessels around stenotic or occluded site (SVSOS), in patients with multiple high-resolution magnetic resonance imaging (HRMRI) examinations. <br> Methods Retrospectively reviewed 20 patients with multiple HRMRI examinations for MCA stenosis or occlusion in Peking Union Medical College from July 2007 to March 2015, and analyzed the relationship between stenotic or occluded MCA and SVSOS. <br> Results Seven patients’ MCA changed from stenosis to occlusion with multiple HRMRI examinations (35.00%), while 13 patients’ MCA remained stenotic. Six cases with SVSOS were witnessed in patients with MCA change (85.71%), while 3 patients without MCA change had SVSOS (23.08%). There was signiifcant difference in two groups (P=0.02). <br> Conclusion Small vessels around stenotic or occluded site (SVSOS) might be associated with the aggravation of stenosis degree.关键词
