摘要
目的探讨外伤性脑梗死的发病机制和治疗效果。方法回顾性分析中重度脑外伤患者经CT、MRI证实的外伤性脑梗死患者的临床、影像学表现及治疗结果。结果 709例中重度脑外伤中64例出现脑梗死,发病率为9.0%。脑梗死发生时间为外伤后48 h^2周,38例发生于去骨瓣减压术后,35例发生在基底核区。随访6个月:恢复良好31例,中度残废18例,重度残废5例,植物状态6例,死亡4例。结论外伤性脑梗死的发生与脑血管钝性损伤、低灌注压、颅内压增高及去骨瓣减压术密切相关。治疗上强调早期积极处理预防脑梗死的发生。
Objective To investigate the pathogenesis and treatment effects of posttraumatic cerebral infarction(PTCI).Methods The clinical manifestations,CT and MR imaging and treatment effects of patients with PTCI were retrospectively analyzed.Results Of the 709 consecutive patients with moderate or severe traumatic brain injury(TBI),64(9%) had a confirmed PTCI.The cerebral infarction developed between 48 hours and 2 weeks after injury.In 38 cases,the PTCI occurred after decompression craniotomy.In 35 cases,the PTCI appeared at the area of basal ganglia.The follow-up was carried out from 6 months after injury.4 patients died,6 were in a vegetative state,5 had severe disability,18 had middle disability and 31 showed favorable outcome.Conclusion The blunt cerebral vascular injury,low systolic BP,intracranial hypertension,and decompression craniotomy may be risk factors for PTCI in patients with moderate or severe traumatic brain injury.The early positive clinical management reduces the risk of infarction.
