3、performed with a 2.0 MHz transducer in 80 healthy volunteers ranging in age from 20 to 70 years (mean 48.9 years).ResultsA venous signal away from the probe and adjacent to the posterior cerebral artery,considered to correspond to the basal vein.Mean blood flow velocity was (13.62.2) cm/s.Analysis f

4、or age dependency revealed a trend of decreasing values with increasing age.No significant intraindividual side-to-side differences were found.A venous signal away from the probe and paralleing the middle cerebral artery,interpreted as corresponding to the deep middle cerebral vein,was found in 34 %

5、 of the subjects with similar velocities.The flow direction of the straight sinus was toward the probe,mean blood flow velocity was (17.34.2) cm/s.ConclusionTranscranial Doppler ultrasound can also be used for evaluation of the basal cerebral veins.【Key words】Ultrasonography,Doppler,transcranial;Cer

6、ebralveins;Hemodynamics本研究旨在探討顱內(nèi)靜脈的經(jīng)顱多普勒(TCD)檢查方法,建立國人顱內(nèi)靜脈血流的正常參考值,證實年齡及性別因素對靜脈血流的影響。對象與方法一、研究對象受試者80例,男女各半;年齡2070歲,平均48.9歲,0.05)。由于BVR檢出率近100%,故分析了BVR平均血流速與年齡和性別的相關(guān)性(見表2)。女性BVR平均血流速略高于男性,但統(tǒng)計學無明顯差異(P0.05)。40歲組的BVR平均流速明顯低于40歲組(P0.001)。表180例健康人腦靜脈血流速和PI檢測結(jié)果(s)指標Vs(cm/s)Vd(cm/s)Vm(cm/s)PIBVR17.22.612.1
