CT显示在基底节、内囊或皮质下白质大于1.5cm的脑梗塞同较小的皮质下梗塞相比,可能更多见于脑栓塞。较小的皮质下梗塞传统将其归类于腔隙性梗塞,通常为高血压性小血管闭塞所致。深部大而积脑梗塞产生的临床综合征同腔隙性梗塞相似,但前者可能同时伴有皮质受累症状。本文研究了51例病灶累及内囊、基底节或皮质下白质的大面积脑梗塞,以评价潜在的颈动脉、心脏栓子源以及梗塞后失语症、偏侧忽略和注视麻痹的发生率。
CT showed that cerebral infarcts larger than 1.5 cm in the basal ganglia, internal capsule or subcortical white matter may be found more often in cerebral emboli than smaller subcortical infarcts. Smaller subcortical infarcts have traditionally been classified as lacunar infarcts, usually due to occlusion of hypertensive small vessels. Clinical syndromes caused by deep massive brain infarction are similar to lacunar infarcts, but the former may be accompanied by symptoms of cortical involvement. In this study, 51 patients with massive infarcts involving the inner capsule, basal ganglia, or subcortical white matter were studied to assess the potential incidence of carotid and cardiac emboli, as well as post-infarction aphasia, hemiparesis and paralysis.
