目的 对 149例腔隙性脑梗塞患者的头颅 CT、部分 TCD及临床特征作回顾性分析。方法 根据临床表现进行分类 ,观察病灶的部位、大小及脑底的动脉系统血流速度的改变。结果 本组患者发病年龄较大 ,6 3.1%有慢性高血压病史 ,临床表现为复杂化、多样化。 CT检查显示腔隙灶以多发为主。TCD可反映椎 -基底动脉系统及颈内动脉系统的血管弹性及血流速度 ,对腔隙性脑梗塞的诊断有一定帮助 ,但定位不甚准确。结论 CT是诊断腔隙性脑梗塞的最佳手段
Objective To retrospectively analyze cranial CT, partial TCD and clinical features of 149 patients with lacunar infarction. Methods According to the clinical manifestations were classified, the lesion location, size and cerebral artery velocity changes. Results The incidence of this group of patients was older, 6 3.1% had a history of chronic hypertension, clinical manifestations of complications and diversification. CT examination showed that the cavity focus to multiple-based. TCD can reflect the vertebrobasilar artery system and the internal carotid artery system of vascular elasticity and blood flow velocity, lacunar infarction diagnosis of some help, but the positioning is not accurate. Conclusion CT is the best way to diagnose lacunar infarction
