目的：研究小儿外伤性脑血管闭塞的临床与ＣＴ表现。探讨其形成的机理及ＣＴ诊断价值。方法：对１０例有明确颅外伤及伤后肢体偏瘫等体征的幼儿进行了ＣＴ扫描观察并记录。结果：２例正常，１例大面积脑梗塞、７例腔隙性脑梗塞（１例于丘脑、６例于内囊）。结论：外伤性腔隙性脑梗塞在幼儿中常见，而且大部分病变都发生在内囊（６∶１）。其产生的机理可能是脑外伤引起脑血管痉挛性闭塞所致脑缺血性坏死。ＣＴ扫描对其诊断的确立具有重要价值
Objective: To study the clinical and CT findings of pediatric traumatic cerebrovascular occlusion. To explore the mechanism of its formation and CT diagnostic value. Methods: Totally 10 children with signs of craniocerebral injury and limb hemiplegia after injury were observed and recorded by CT scan. Results: Two cases were normal, one case had massive cerebral infarction, and seven cases had lacunar infarction (one in thalamus and six in internal capsule). CONCLUSIONS: Traumatic lacunar infarcts are common in young children and most lesions occur in the internal capsule (6: 1). Its mechanism may be brain trauma caused by cerebral vasospasm occlusion of cerebral ischemic necrosis. CT scan for the establishment of its diagnosis of great value
