外伤性脑梗死的CT表现分型与临床预后关系探讨

A Prospective Research for CT Classification and Its Clinical Prognosis in Patients with Traumatic Brain Infarction

目的探讨外伤性脑梗死的CT表现及分型,评价CT分型对判断临床预后的价值。资料与方法回顾性分析102例外伤性脑梗死的CT表现,结合临床进行CT分型,并与临床预后作对比分析。结果将外伤性脑梗死分为5型:Ⅰ型,腔隙性梗死型(n=44);Ⅱ型,单脑叶型(n=20);Ⅲ型,多脑叶型(n=15);Ⅳ型,挫伤出血型(n=15);Ⅴ型,小脑与脑干型(n=8)。其中Ⅰ～Ⅱ型疗效较好,Ⅲ～Ⅴ型病情严重,病死率和致残率高。结论外伤性脑梗死CT分型有助于判断临床预后。

Objective To discuss CT image features and classification of the post-traumatic cerebral infarction and evaluate the relationship between CT classification and the clinical prognosis.Materials and Methods The CT image features of 102 cases with post-traumatic cerebral infarctions were retrospectively analyzed. CT classification was made according to the clinical presentations and compared with clinical prognosis.Results There were five types of post-traumatic cerebral infarctions on CT appearance: Type Ⅰ (n=44), the lacunar cerebral infarct; Type Ⅱ (n=20), the infarct confined to a single lobe; Type Ⅲ (n=15), mutiple cerebral lobes infarct; Type Ⅳ (n=15), a mixed type, both the contusion and hemorrhage; Type Ⅴ (n=8), cerebellar and brainstem infarct. Most of the patients with type Ⅰ-Ⅱ of cerebral infarction recovered favorably; the mortality and disability rate were high in the patients with type Ⅲ-Ⅴ cerebral infarct because of their severe clinical conditions.Conclusion CT classification of post-traumatic cerebral infarctions would be helpful to provide reliable evidence for clinical prognosis.
