目的应用彩色多普勒超声研究高血压患者颈动脉内膜中层厚度对预测高血压脑卒中的价值。方法应用彩色多普勒超声检测100例单纯高血压患者及50例健康人颈动脉的内膜中层厚度(IMT)及斑块情况,比较单纯高血压患者与高血压合并脑卒中患者颈动脉内膜中层厚度的差别。结果100例高血压患者中内膜中层增厚者94例,占94%;动脉粥样斑块形成62例,共123处斑块。脑卒中组内膜中层厚度及斑块形成明显多于单纯高血压组。结论彩色多普勒超声能有效检测颈动脉管壁及管腔的变化,在临床预测高血压脑卒中具有重要的参考价值。
Objective To evaluate the value of carotid artery intima-media thickness in prediction of hypertensive stroke by color Doppler ultrasonography. Methods The intima-media thickness (IMT) and plaque of 100 carotid arteries of 100 hypertensive patients and 50 healthy people were detected by color Doppler ultrasonography. The carotid artery intima-media thickness The difference in middle layer thickness. Results In 100 cases of hypertensive patients, 94 cases of intimal thickening were involved, accounting for 94%. Atherosclerotic plaques formed 62 cases with 123 plaques. Intima-media thickness and plaque formation in stroke group were significantly more than those in simple hypertension group. Conclusion Color Doppler ultrasound can effectively detect the changes of the carotid artery wall and the lumen, which is of great value in the clinical prediction of hypertensive stroke.
