经颅多普勒超声和CT在腔隙性脑梗死中的应用价值

目的探讨经颅多普勒(TCD)与CT在腔隙性脑梗死中的诊断价值.方法对210例腔隙性脑梗死患者行TCD与CT检测,并进行对比分析.结果CT首次确诊为腔隙性脑梗死149例(70.9%),而TCD检测结果193例异常,异常率达91.9%,异常率明显高于CT.CT显示72.38%的病例发生在基底节区域,TCD则显示病灶区的脑血流动力学异常,表现为动脉供血不足、脑血管痉挛、血管狭窄、脑动脉硬化症.结论同时对患者行TCD和CT检测,对腔隙性脑梗死患者的临床诊断、病因和危险因素的追查可提供依据.

Study of the TCD and CT in patients with lacunar infarction

Objective To discuss the diagnostic value of transcranial Doppler(TCD) and CT in the lacunar infarction. Methods TCD and CT examinations were applied on 210 cases with lacunar infarction.And the results were compared and analyzed. Results 149 cases(70.9%) are diagnosed as lacunar infarction by CT examination at the first time,and 193(91.9%) cases are giagnosed as abnormality by TCD examination.The rate of abnormality of TCD was much higher than CT.The results of CT showed that the infarction took place in the basal ganglia in 72.38% cases, while the results of TCD showed that the hemodynamics of brain of focus was abnormal,which includes the blood flow insufficiency of artery ,cerebral vessels spasm ,blood vessel straitness, cerebral arteriosclerosis. Conclusion Applying the TCD and CT examination at one time can offer evidences for clinical diagnosis and finding etiological and risk factors for the lacunar infarction.
