| 目的 研究单侧动脉粥样硬化性MCA/ICA狭窄与闭塞的急性缺血性脑卒中患者在MRI上的病灶模式。方法 利用DSA定位MCA/ICA重度狭窄(≥70%)与闭塞,常规MRI-FLAIR序列研究MCA/ICA病变引起脑梗死的形态学表现。有潜在心源性栓子患者除外。结果 105例患者(ICA 64例, MCA 41例)MRI上缺血病灶模式分为4种:区域梗死、皮质下梗死、边缘带梗死、弥散小梗死。MCA组中皮质下梗死的发生率较ICA组高(48.8% VS 21.9% ; P<0.05);ICA组中区域梗死的发生率较MCA组高(39.1% VS 4.9%,P<0.05)。结论 动脉粥样硬化性MCA病变患者多见于皮质下梗死,而ICA病变患者多见于区域梗死。 |

| Objective To investigate lesion patterns on MRI in acute cerebral ischemic stroke patients with unilateral atherosclerotic ICA/MCA stenosis or occlusion. Methods Atherosclerotic ICA/MCA disease as ≥70% severe stenosis or occlusion was defined by DSA. Topographic patterns were investigated on MRI and FLAIR sequences in cerebral infarct patients with ICA/MCA occlusive disease. Patients with potential cardiac sources of embolism were excluded. Results Among the 105 patients, 64 met the criteria for atherosclerotic ICA and 41 met the criteria for MCA disease. The topographic patterns of the ischemic lesions shown on MRI were subdivided into four groups: territory infarcts, subcortical infarcts, border-zone infarcts, and several disseminated small infarcts. The occurrence ratio of subcortical infarcts was greater in the MCA group than in the ICA group (48.8% vs 21.9%, P<0.05). The occurrence ratio of territory infarcts was greater in the ICA group than in the MCA group (39.1% vs 4.9%, P<0.05). Conclusion Subcortical infarcts were more shown in atherosclerotic MCA disease, territory infarcts were more shown in atherosclerotic ICA disease. |
