经颅多普勒超声在多发性微小脑梗塞的应用

TRANSCRANIAL DOPPLER EVALUATION OF MULTIPLE CEREBRAL MINI-INFARCTS

对20例经MRI诊断的多发性微小脑梗塞(LS7例,BD8例,未归类5例)进行 TCD 研究。结果发现:6例颅内动脉流速正常,5例椎基动脉流速降低,3例颅内动脉流速普遍降低,5例颅内个别动脉流速增高,1例颅内动脉流速普遍增高。分析了TCD检查结果,认为TCD能检测MRI不能发现的血管功能性异常,并可为随访病情、评价疗效提供客观依据。

20 cases of MRI-diagnosed multiple cerebral mini-intarcts(lacunar state,7 cases;Binswanger'disease,8 cases;unclassified,5 cases)were studied with TCD.The fol-lowing results were found:normal cerebral blood flow velocity(CBFV),6 cases;red-uced vertebro-basilar system CBFV, 5 cases;CBFV reduced generally,3 cases;increasedCBFV in individual cerebral artery,5 cases;CBFV increased generally,1 case It wagpresumed that abnormal vasomotor changes invisible on MRI could be monitored withTCD to follow up the disease course and evlauate the therapeutic effect of medicalintervention.
