TCD对175例中老年发作性眩晕的诊断意义

本文对１７５例中老年发作性眩晕的临床，ＣＴ、ＭＲＩ和ＴＣＤ进行了检测。并结合１７７名同年龄组健康人正常值进行对比分析。１７５例中，男１０２例，女７３例，平均年龄５９．５岁。分四组：１颈性晕组（５６人）合并明显的颈椎病。２、Ｖ－ＢＡＴＩＡ组（４２人）有眩晕及局灶神经证，２４小时内消失。３、Ｖ－ＢＡ系统脑梗塞组（６２人）。４、颈性眩晕并ＴＣＤ转颈组（１５人）。ＴＣＤ，总异常率６３．２％；有神经征阳８１

Diagnostic Significance of TCD in l75 Aged patients with Acute Vertiginous Attack

TCD dingnostic significances were compared in l75 aged patients with acute vertiginous,at-tack to normal 177 healthy individuals.Patients divided into 4 groups:1.Cervical vertigo group(56)complicted with severe cervical spondylosis.2.V-BA TIA group(42).3.V-BA Stroke group(62).4.Cervical vertigo in-duced by neck rottqtion test group(15).The total abnormality rate of TCD was 63.2%,81.2% with positive local neurological signs,51.0% without.91.0% with poxitive neck rotation test.VA:BA=1.5:1.0.The abnormal-ity rate of CT and MRI were 40.25%,39.48% respectively,It showed that TCD is very benefit for early diagno-sis and sequential observations of acute CVD attack Synchronous observations of blood cirvulation of circle of willis were performed.It showed that during acute inchemia of VA and BA syatem,the anterior blood circulations of ACA,MCA and PCA have abnormal compensatory hemodynamics,especially in PCA,while PI is more sensi-tive than RI.As for F and Q tests to the above 4 groups,only neck rotation test group has significant statistical
