目的:评估经颅多普勒超声检查在2型糖尿病患者脑血管病变的临床应用价值。方法:76例2型糖尿病患者和62例健康体检者行TCD检查,对比分析两组人群大脑中动脉(M CA)、颈内动脉末端(ICA)、基底动脉(BA)的平均血流速度(Vm)、搏动指数(P I)、屏气指数(BH I)的差异。结果:患病组平均血流速度(Vm)较对照组显著加快(P<0.01),搏动指数(P I)高于对照组(P<0.01),屏气指数明显低于对照组(P<0.01)。结论:BH I客观地反映了血管的反应性,TCD检查可为2型糖尿病患者脑血管疾病的防治提供依据。
Objective: To evaluate the clinical value of transcranial Doppler ultrasonography in the diagnosis of cerebrovascular disease in type 2 diabetic patients. Methods TCD was performed in 76 patients with type 2 diabetes mellitus and 62 healthy people. The mean blood flow velocity (M CA), ICA and BA in two groups were compared Vm), pulsatility index (PI), breath holding index (BH I) differences. Results: The mean blood flow velocity (Vm) of the sick group was significantly higher than that of the control group (P <0.01), and the pulsatility index (PI) was higher than that of the control group (P <0.01) . Conclusion: BH I objectively reflects the vascular reactivity, TCD examination can provide a basis for prevention and treatment of cerebrovascular disease in patients with type 2 diabetes mellitus.
