三维超声在高血压病患者颈动脉粥样斑块研究中的应用

USE OF THREE-DIMENSIONAL ULTRASOUND TO RESEARCH CAROTID ATHEROSCLEROSIS IN PATIENTS WITH HYPERTENSION

目的：探讨三维超声在诊断高血压颈动脉粥样硬化方面的图像特征和临床价值。方法：90例高血压病患者，男68例，女22例，年龄60．7±5．3岁。图像采集系用飞力浦iU22超声诊断仪和三维超声系统。应用二维及三维超声测量双侧颈总动脉和颈内外动脉的血管内斑块体积。结果：本研究中67例患者被检出斑块，23例患者未被检出斑块。颈动脉斑块总体积与高血压病史及高血压程度成正相关。结论：三维超声图像能够完整地显示出立体的颈内动脉管腔及斑块的部位、形状、大小，为评价高血压痛患者的动脉粥样斑块提供了较二维超声图像更丰富的信息，具有重要的临床价值。

Objective To probe the value of using three-dimensional ultrasonography to diagnose carotid atheroslerosis in patients with hypertension. Methods Nighty patients with hypertension （male ： 68, female ： 22）, aged from 45 to 77 years, were examined. The instruments used included Fillip iU22 color Doppler ultrasonography diagnosis system and three-dimensional ultrasonography sytem. Two-dimensional ultrasound and three-dimensional ultrasound were employed to measure the volume of atherosclerotic plaques in two side carotid artery , include common carotid artery , internal carotid artery and external carotid artery. Results IN this study, 67 patients were found atherosclerotic plaques. In contrary, 23 patients were not found any atherosclerotic plaque. There is positive correlation between the sum of the volume of carotid atherosclerotic plaques and the course of hypertension , as well as the level of blood pressure. Conclusion Compared with the two dimensional ultrasonography, the three dimentional color Doppler ultrasonography of atherosclerotic plaques is more intuitionistics of the pathological changes, more exhaustive of the pathological characteristics and more accurate in the pathological evaluation.
