目的分析颅脑外伤后并发脑梗死的发生机制,探讨早期预防、救治的措施。方法回顾分析20例颅脑损伤术后患者发生脑梗死的临床资料。结果发病6个月后按GOS标准评价,20例患者中死亡6例,重残3例,中残1例,良好10例。结论重型脑外伤术后应积极保持脑灌注压、维持血压及血氧,降低颅内压,改善脑血管痉挛,早期扩管改善微循环,有利于降低脑梗死的发生和死残率,改善预后。 Objective To analyze the mechanism of cerebral infarction after traumatic brain injury and to explore the measures of early prevention and treatment. Methods The clinical data of 20 patients with cerebral infarction after craniocerebral injury were retrospectively analyzed. Results According to the GOS standard 6 months after onset, 6 of 20 patients died, 3 were severely disabled, 1 was moderately disabled, and 10 were good. Conclusions Severe traumatic brain injury should maintain cerebral perfusion pressure, maintain blood pressure and blood oxygen, reduce intracranial pressure, improve cerebral vasospasm, and improve blood circulation and microcirculation in early stage of traumatic brain injury. It is helpful to reduce the incidence and mortality of cerebral infarction and improve prognosis .
