本文通过对48例证实为大面积脑梗塞的病例进行回顾性分析后发现:大面积脑梗塞早期(发病24小时以内)临床症状危重,多有突发性失语,神志不清,同时伴有肢体偏瘫和肌力下降。CT表现为梗塞区脑实质密度不同程度减低,白—灰质交界线模糊,相应脑沟脑裂变窄变形,同时还可见阻塞脑动脉主干密度增高表现。应用高分辨力CT扫描并结合临床表现可大大提高大面积脑梗塞诊断的准确性和及时性,为临床溶栓治疗方案的及时制定,减少致残和死亡率提供帮助。
In this paper, we retrospectively analyzed 48 cases confirmed as large-area cerebral infarction and found that the clinical symptoms of large-area cerebral infarction in the early (within 24 hours of onset) were serious, with sudden aphasia, unconsciousness, accompanied by limbs Hemiplegia and decreased strength. CT showed infarction area brain parenchyma density decreased to varying degrees, white-gray matter obscured the corresponding line, the corresponding narrow brain fissure deformity, while also visible obstruction of increased cerebral artery trunk density. The application of high resolution CT scan combined with clinical manifestations can greatly improve the accuracy and timeliness of diagnosis of large-area cerebral infarction and provide help for the timely formulation and reduction of disability and mortality in clinical thrombolytic therapy.
