外伤性脑梗死的CT诊断

目的总结外伤性脑梗死的CT特征,探讨其发生机制,揭示其对疾病预后的判定价值。方法回顾性分析40例外伤性脑梗死患者头颅CT表现及相关临床资料。结果轻微外伤引起的脑梗死多发于儿童,好发部位为基底节内囊区,预后较好;重症外伤引起的脑梗死好发于成人,发病部位多见于颅内血肿同侧,且大脑后动脉支配区域最为多见,预后较差。结论CT扫描对外伤性脑梗死的诊断及预后判定有重要价值。

Analysis of CT scan in patients with post-traumatic cerebral infarction

Objective To sum up the characteristics of CT scan in patients with post-traumatic cerebral infarction following head injury and then detect the pathogenesis of this disease. And at last the value of the imaging to judge the prognosis will be showed. Methods The CT manifestation and clinical materials in 40 cases of patients with traumatic cerebral infarction were analyzed retrospectively. Results Infarctions following mild injuries often occurred in children, located in basal ganglia and internal capsule and the prognosis was good. Infarctions resulting from severe injuries usually occurred in adults, located in the ipsilateral of hematoma in brain, and often in the region dominated by posterior cerebral artery with the poor prognosis. Conclusion CT scan makes an important role in the diagnosis of this disease and even the evaluation of the prognosis.
