目的:评价高血压脑动脉硬化患者检测脑导纳(ADL)血流指标及其临床意义。方法:对1200例确诊为老年原发性高血压及脑动脉硬化患者行脑导纳检测,分析脑导纳各项指标的特点,并与500例健康者对照,结果:脑动脉硬化表现为流入容积速度(波幅HS与快速充盈时间BS)比值显著降低,流入阻力指数(转折高度HH与波幅HS)比值显著降低,Ⅰ+Ⅱ相面积百分比显著降低(ρ<0.01),Ⅳ相面积百分比显著增高,导纳微分环(ADL)Ⅳ/ADLⅠ+Ⅱ显著增高,同时双侧ADL波形环明显切迹或变异(ρ<0.01)结论:高血压脑动脉硬化患者检测脑导纳明显特征性改变,结果可评价高血压脑动脉硬化患者脑血管功能情况及脑供血状况提供客观指标。
Objective: To evaluate the blood flow index (ADR) and its clinical significance in patients with hypertensive cerebral arteriosclerosis. Methods: 1200 brain diagnosed as elderly patients with essential hypertension and cerebral arteriosclerosis were detected by brain admittance, the characteristics of brain admittance of various indicators, and with 500 healthy controls, the results: cerebral arteriosclerosis manifested as inflow The ratio of volumetric velocity (amplitude HS to fast filling time BS) decreased significantly, the ratio of inflow resistance index (turning height HH to amplitude HS) decreased significantly, the area percentage of Ⅰ + Ⅱ phase decreased significantly (ρ <0.01), and the phase area percentage of Ⅳ phase increased significantly (ADL) Ⅳ / ADLⅠ + Ⅱ significantly increased, meanwhile the bilateral ADL waveform ring significantly notch or mutation (ρ <0.01) .Conclusion: Hypertensive cerebral arteriosclerosis in patients with detectable brain trabecular obvious characteristic changes, the results Evaluation of cerebrovascular function in patients with hypertensive cerebral arteriosclerosis and cerebral blood supply provide objective indicators.
