脑干腔隙性梗塞的MRI、TCD与临床

MRI、TCD and clinical manifestations of brainstem lacunar infarction

本文对８５例脑干腔隙性梗塞（腔梗）患者的头颅ＭＲＩ、部分ＴＣＤ及临床特征作回顾性分析。结果：本组患者发病年龄较大，７５％有长期高血压史，临床表现为复杂性、多样化特点，且多数缺乏典型的交叉或脑干孤立症征。ＭＲＩ扫描显示腔隙灶以桥脑腹侧居多，病灶＜０．５ｃｍ者可无症状或症状轻微。ＴＣＤ可很好反映椎－基底动脉系统的血管弹性及血流速度，对脑干腔梗的诊断有一定的帮助，但定位不甚准确。ＭＲＩ仍是诊断脑干腔梗的最佳手段。

The manifestation of MRI,TCD and clinic of 85 patients with brainstem lacunar infarction was analyzed retrospectively.We found that the patients age was rather older, 75% of which had histories of hypertension.Clinical manifestations of them were more complex and varied,and the majority didnt present the typical lacunar syndromes.In MR imaging,the leisions of lacune appeared commonly in the ventral region of the pons,the patient may be asymptomatic when lacunes were <0.5cm in size.TCD can reflect the changes of flow velocity of the vertebralbasilar arteries, and can help the diagnosis.We considered that MRI is the best way to diagnose the brainstem lacunar infartion.
