脑桥基底部梗死95例临床分析

目的研究脑桥基底部梗死的临床表现及影像改变。方法回顾性地分析95例脑桥基底部梗死的原始资料。结果脑桥基底部梗死是后循环常见的梗死，据其是否涉及基底部表面分为基底动脉分支病(BABD)及小动脉病变。临床上主要表现为病变对侧中枢性面瘫及肢体瘫痪，常伴构音障碍、头晕、共济失调、偏身感觉障碍等。根据临床表现往往不易与内囊梗死区别。结论脑桥基底部梗死比我们所认识到的更为常见，临床表现与内囊梗死相似，罕见有经典的脑桥综合征。

The clinical analysis of pontine basal infarction

Objective To evaluates the clinical and imaging features of pontine basal infarction. Methods The clinical and imaging data of 95 cases of pontine basal infarction were retrospectively studied. Results Pontine basal infarction was a common infarction in the posterior circulatory system. The pathogenic mechanisms were mainly basilar artery branch disease (BABD) and small artery disease. On MRI the infarction presents extending to the basal surface or without extension to basal surface. The main clinical findings were:hemiparesis,often together with dysarthria,vertigo,ataxi,hemiparethesia,et al. It was not easy to be differentiated from capsule infarction clinically. Conclusion The pontine basal infarction is more common than we have known. The clinical features are similar to those of inner capsule infarction. Rarely dose the typical pontine syndrome exist.
