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。 This paper retrospectively analyzed the cranial MRI, partial TCD and clinical features in 85 patients with lacunar infarction. Results: The incidence of this group of patients is older, 75% have a long history of hypertension, the clinical manifestations of complexity and diversity, and most of the lack of typical cross or brainstem isolation syndrome. MRI scan showed that the majority of lacunar pontine ventral pontine lesions less than 0.5cm may be asymptomatic or mild symptoms. TCD can well reflect the vertebrobasilar artery system of vascular elasticity and blood flow velocity, the diagnosis of brainstem stems have some help, but the positioning is not accurate. MRI is still the best way to diagnose brainstem stem.
