目的研究高血压患者的颈动脉粥样硬化的发生情况。方法对66例高血压患者及30例正常对照者的颈动脉用HP-SONOS 5500彩色多普勒超声诊断仪及高频探头检测其内径(D),内膜-中层厚度(IMT),斑块的发生及峰值流速(Vs),舒张末速度(Vd),脉动指数(PI)及阻力指数(R I),检测结果进行统计学分析。结果高血压患者的颈动脉内膜-中层厚度(IMT)及斑块的发生率明显高于对照组,Vs,PI,R I等血流动力学指标明显低于对照组。结论颈动脉内膜-中层厚度、斑块的发生率与高血压有相关性,二维彩色多普勒超声能简便、准确对颈动脉进行检测,进而对高血压患者动脉粥样硬化的早期表现提供有价值的指标。
Objective To study the incidence of carotid atherosclerosis in hypertensive patients. Methods The carotid arteries of 66 patients with hypertension and 30 normal controls were examined by HP-SONOS 5500 color Doppler sonography and high-frequency probe to detect the internal diameter (D), intima-media thickness (IMT) (Vs), end-diastolic velocity (Vd), pulsatility index (PI) and resistance index (RI) were measured. The results were statistically analyzed. Results The carotid intima - media thickness (IMT) and plaque incidence were significantly higher in patients with hypertension than those in the control group. The hemodynamic indexes such as Vs, PI and R I were significantly lower than those in the control group. Conclusions Carotid artery intima-media thickness and the incidence of plaque are correlated with hypertension. Two-dimensional color Doppler ultrasound can be used to detect the carotid artery easily and accurately, and then the early manifestation of atherosclerosis in hypertensive patients Provide valuable indicators.
