脑干梗死的临床特点

Clinical characteristics of brainstem infarction

目的探讨脑干梗死的临床特点。方法回顾性分析42例急性脑干梗死患者的临床资料。结果 42例患者均为急性起病,临床表现为交叉性瘫痪18例;非交叉性瘫痪如中枢性面舌瘫、偏瘫14例,单瘫、脑神经瘫痪等10例。所有患者MRI检查均发现病灶,8例发病<6 h的患者DWI均发现新鲜责任病灶。结论脑干梗死临床表现有交叉性瘫痪和非交叉性瘫痪,且瘫痪程度较轻;DWI有助于早期确诊。

Objective To investigate the clinical characteristics of brainstem infarction. Methods The clinical data of 42 patients with acute brainstem infarction were analyzed retrospectively. Results All of the 42 cases were acute onset. The clinical manifestation was crossed hemiparalysis in 18 cases, uncrossed hemiparalysis such as central faciolingual paralysis or hemiplcgia in 14 cases, single limb paralysis or cranial nerve paralysis in 10 cases. The brainstem infarct lesions were found by skull MRI in all the cases. And the fresh responsibility lesions in 8 cases who onset less than 6 h were found out by diffusion weighted imaging （DWI）. Conclusions The clinical manifestation of brainstem infarction are crossed hemiparalysis and uncrossed hemiparalysis. The paralysis degree is slight. DWI can be helpful to diagnosis in the early stage of brainstem infarction.
