糖尿病CBA检测的临床意义和价值

CLINICAL SIGNIFICANCE AND VALUE OF CBA EXAMININA- TION IN DIABETICS

应用CBA对糖尿病进行检测发现动态阻力（DR）、外周阻力（Rv）、脉搏波速（Wv）,特性阻抗（Zcv）和颈动脉血流量（Qmean）5个参数是监测糖尿病动力学动态变化的主要指标,脑循环动力学参数（CVDI）异常反映糖尿病存在着脑供血不足,微循环障碍,脑动脉硬化,血管调节功能障碍,Ⅰ型糖尿病CVDI异常特点为双侧轻度异常,Ⅱ型糖尿病特点既有双侧异常,又有单侧异常,重度异常者皆为Ⅱ型糖尿病。Ⅱ型糖尿病合并脑血管出现脑动脉硬化、微循环障碍,闭锁状态下小血管动力学异常和临界压升高的特点,此点可视为Ⅱ型糖尿病发生合并脑血管病的先期表现,应做CT等予以证实。

Diabetics were examined with CBA. It was found that D, R, W, Z, and Qmean were 5 major indices in monitoring the trends of cerebrovascular hemodynamics of deabetics. Abnormalities of CVDI indicated that there were inadequate blood supply, microcirculation obstruction, cerebrovascular sclerosis, and disfunction of vscular regulation. CVDI abnormalities in type-1 diabetics were slight and bilateral, but in type-2 diabetics they could be bilateral or unilateral. Severe abnormalities were all detected in type-2 cases. When Cerebrovascular disease (CVD) occured with type-2 diabetes, it. was charactered by cerebrovascular sclerosis.microcirculation obstruction, hemobynamics abnormalities of small vascular under locded-in state and critical pressure increase, and these characteristics of CVDI can be taken as preliminary manifestation of CVD, which should be testified by CT examination.
