目的:探讨脑干梗死的临床特征,影像学特点及并发症的诊治,提高对本病的诊断率及治愈率。方法:将38例脑干梗死患者神经体征与头颅CT及MRI对照,分析探讨本病的特点。结果:延髓及中脑梗死均具有交叉性麻痹,脑桥梗死则有不同的临床表现,可概括为四种类型:交叉性麻痹,四肢瘫,纯偏身感觉障碍,偏瘫并偏身感觉障碍。结论:MRI为诊断脑干梗死最有意义的检查,本病并发症多,预后差。
Objective: To investigate the clinical features of brain stem infarction, imaging features and complications diagnosis and treatment to improve the diagnosis of the disease and the cure rate. Methods: Thirty-eight patients with brain stem infarction were selected for neurological signs and head CT and MRI contrast analysis of the characteristics of the disease. Results: The medulla oblongata and midbrain infarction all had the cross paralysis. The pontine infarction had different clinical manifestations. It could be classified into four types: cross paralysis, quadriplegia, pure partial sensory dysfunction, hemiplegia and partial sensory dysfunction. Conclusion: MRI is the most meaningful examination for diagnosis of infarction of brain stem. The disease has many complications and the prognosis is poor.
