在无症状性颈动脉狭窄病人的 CT 扫描上,常发现无症状性脑梗塞(或称无症状卒中),后者与动脉狭窄的关系未明。该文就此进行了研究。作者共比较了3组病人的 CT 所见。组1,为因无症状性颈部杂音接受颈动脉 Doppler 扫描,并证实有无症状性狭窄者,共115例;组2,为 TIA 但颈动脉正常者,共63例;组3,有 TIA 且有颈动脉狭窄者,共203例。颈内动脉狭窄分轻(35%～50%)、中(50%～75%)和重(>75%)三度。3组的年龄性别无显著差异。结果 381例 CT 中,137例阳性全部为小病变
Asymptomatic cerebral infarction (or asymptomatic stroke) is often found on CT scans in patients with asymptomatic carotid stenosis, the latter not being clearly related to arterial stenosis. This article has carried on the research to this. The authors compared a total of 3 patients with CT seen. Group 1: 115 patients with asymptomatic stenosis undergoing Doppler scan of carotid artery and confirmed asymptomatic stenosis; Group 2 with TIA but normal carotid artery, 63 patients in total; Group 3 with TIA And there are carotid artery stenosis, a total of 203 cases. Internal carotid artery stenosis (35% to 50%), moderate (50% to 75%) and severe (> 75%) third degree. There was no significant difference in age and sex among the three groups. Results Of the 381 CT cases, 137 were all small lesions
