摘要
为了观察糖尿病和高血压病对脑血流动力学的影响 ,我们采用经颅多普勒检测了糖尿病、高血压病以及糖尿病 +高血压三组患者脑底动脉的血流速度。结果为糖尿病组 ( n=4 8)的血流异常率为4 1.7% ,高血压病组 ( n=160 )的异常率为 30 % ,而糖尿病 +高血压病组 ( n=35)的异常率则高达 82 .9% ,明显高于前两组 ( P<0 .0 0 5)。各组患者都以 MCA的血流异常最为突出 ,其次为 ACA、CS、BA、VA和PCA,而糖尿病 +高血压病组的 CS损害亦较为突出。认为高血压病的脑血管损害随病情进展而增加 ;糖尿病的脑血管损害较高血压病多见 ,而这两类疾病一旦同时存在 。
The aim of our study was to observe the effect of diabetes melitus and hy- pertension on cerebral hemodynamics.The flow velocity of cerebral basal arteries were inves- tigated with transcranial Dopplersonography(TCD) in the group of diabetesmellitus,hyper- tension and diabetes combined with hypertension.The results that the flow abnormality in diabetic group(n=48) was41 .7% and in hypertensive group(n=1 6 0 ) was30 % ,respective- ly,butin the group(n=35 ) of diabetes combined with hypertension,the abnormality reae- hed as high as 82 .9% and the abnormal rate of the latest group was significantly higher than former two groups(P<0 .0 0 5 ) .The flow abnormality of MCA was most prevailing a- mong all three groups,and next in turn was ACA,CS,BA,VA,and PCA.But CS also suf- fered greaterlesion in thegroup of diabetescombined with hypertension.Itindicated thatthe lesions of cerebral artery in hypertension increased with the progression of the disease.The impairments of brain artery in diabetes was more than that in hypertension,and the impair effecton cerebral artery will sharply increased once both diseases existsimultaneously.
