CTA在外伤性脑梗死的早期诊断及预后判定中的作用

目的探讨CT血管造影（CTA）对外伤性脑梗死（PTCI）早期诊断及患者预后判定的作用。方法回顾性分析30例重型、特重型颅脑损伤并发PTCI患者的临床资料,均行常规头部CT及CTA动态检查。结果伤后CT诊断PTCI 10例,查出时间为伤后（49.5±9.2）h;CTA诊断PTCI 20例,检出时间为（27.7±5.3）h;两者检出时间差异显著（P〈0.05）。按GOS评分评估患者预后,CTA示动脉闭塞14例中,中残3例,重残3例,植物生存2例,死亡6例;CTA示颅内动脉穿支减少8例中,中残2例,重残2例,植物生存1例,死亡3例;CTA示静脉闭塞8例中,中残1例,重残2例,死亡5。结论 CTA可用于重型、特重型颅脑损伤并发PTCI的的早期诊断及预后判定。

Role of CT angiography in early diagnosis and assessment of prognosis in patients with posttraumatic cerebral infarction

Objective To investigate the role of CT angiography（CTA） in early diagnosis and assessment of the prognoses in the patients with posttraumatic cerebral infarction.Methods The clinical data of 30 patients with posttraumatic cerebral infarction after severe or especially severe brain injury, who received routine CT and dynamic CTA examinations, were analyzed retrospectively.Results The posttraumatic cerebral infarction was found by CTA earlier after the brain injury compared to CT（P0.05）. CTA showed that of 30 patients with posttraumatic cerebral infarction, 14 suffered from the arterial occlusion, 8 from the occlusion of the perforative arteries and8 from the venous occlusion. Of 30 patients with posttraumatic cerebral infarction, 5 were moderately disabled, 8 severely disable, 3survived vegetatively and 14 died.Conclusion CTA can be used to early diagnose and assess the prognoses in the patients with posttraumatic cerebral infarction.
