目的探讨多普勒超声对老年高血压患者颈动脉硬化程度的诊断价值。方法采用二维及多普勒超声技术观察105例老年高血压患者和100例正常对照组颈动脉病变及其血流动力学变化,同时检测患者基线血脂、血糖。结果随着高血压分级的逐渐增加以及基线血脂、血糖水平的升高,颈动脉内膜-中膜厚度逐渐增厚且相互比较有显著性意义;随着高血压程度的不断加重,颈动脉斑块的发生率和严重程度也不断增加;血流动力学检测显示老年高血压患者颈总动脉、颈内动脉的收缩期峰值速度、舒张末期速度低于对照组,阻力指数、搏动指数高于对照组。结论彩色超声多普勒可通过检查颈动脉硬化程度,对判断高血压患者有无动脉硬化及两者之间的关系具有重要意义。
Objective To explore the value of Doppler ultrasound in the diagnosis of carotid atherosclerosis in elderly patients with hypertension. Methods Two-dimensional and Doppler ultrasound was used to observe the changes of carotid arteries and hemodynamics in 105 elderly hypertensive patients and 100 healthy controls. Meanwhile, the baseline blood lipid and blood glucose were measured. Results With the gradual increase of hypertension grade and the increase of baseline blood lipid and blood sugar level, the intima-media thickness of carotid arteries gradually became thicker and more significant compared with each other. With the increasing of hypertension, carotid plaque Block incidence and severity also increased; hemodynamic tests showed that elderly patients with carotid artery, internal carotid artery systolic peak velocity, end-diastolic velocity lower than the control group, resistance index, pulsatility index higher than the control group. Conclusion Color Doppler ultrasound examination can detect the degree of carotid atherosclerosis, in order to determine the presence or absence of arteriosclerosis in hypertensive patients and the relationship between the two is of great significance.
