Abstract:
Objective To investigate the correlation between non-lacunar infarcts in the white matter of brain and intracranial or extracranial vessels stenosis.Methods Brain magnetic resonance imaging(MRI) and digital subtraction angiography(DSA) were performed in 30 patients with non-lacunar infarcts in the white matter of brain and the results were analyzed.Results Of 12 cases with focal non-lacunar infarcts in the area of basal ganglion,9 cases were shown occlusion or highly stenosis of proximal segments of unilateral internal carotid artery(ICA) in DSA,2 cases were shown highly stenosis of M1 segment of middle cerebral artery(MCA),and 1 case was normal.Of 6 cases with focal non-lacunar infarcts in the area of basal ganglion and lateral periventricular white matter,3 cases were shown occlusion or highly stenosis of proximal segments of unilateral ICA in DSA,1 case was shown occlusion of C5 segment of unilateral ICA,and 2 cases were shown occlusion of M1 segments of MCA.Of 4 cases with focal non-lacunar infarcts in periventricular white matter or centrum ovale,1 case was shown occlusion of C5 segment of unilateral ICA,2 cases were shown highly stenosis of M1 segments of MCA,and the other one was normal.Of 8 cases with subcortical superior border infarction(SSBI) or subcortical lateral border infarction(SLBI),6 cases were shown occlusion or highly stenosis of proximal segments of unilateral ICA,1 case was shown occlusion of proximal segments of bilateral ICA,and 1 case was shown occlusion of M1 segment of MCA.Conclusion There are strong correlations between focal non-lacunar infarcts in the areas of basal ganglion or lateral periventricular white matter and the stenosis or occlusion of large arteries of ICA system.
