高血压患者颈动脉粥样硬化的超声检测及临床意义

目的了解高血压患者颈动脉粥样硬化的状况,探讨超声检测颈动脉粥样硬化在高血压患者中的临床意义。方法应用二维和彩色多普勒血管超声技术分别检测106例高血压患者颈总动脉内径（CCA）、内-中膜厚度（IMT）、斑块发生率并与29例健康组对照。结果高血压组较对照组颈动脉内径及IMT增加（P〈0.05）;高血压病的严重程度与颈动脉IMT比较,差异有统计学意义（P〈0.05）。结论动脉IMT增厚是动脉粥样硬化的早期特征。超声能早期发现颈动脉粥样硬化,可作为高血压患者筛选缺血性脑血管病高危人群的常规首选检查,有一定的临床价值。

Ultrasonic testing of carotid atherosclerosis and its clinical significance in patients with hypertension

Objective To understand the status of carotid artery atherosclerosis and to investigate clinical significance of ultrasonic testing in diagnosis of carotid artery atherosclerosis in patients with hypertension.Methods Internal diameter of common carotid artery （CCA）,intima-media thickness（IMT）and plaque were measured by two-dimensional ultrasound and colorDoppler in 106 patients with hypertension and then compared with 29 healthy control subjects.Results The CCA and IMT of the hypertension group were greater than those of the control group.There were significant changes in carotid IMT among different degree of hypertension （P 0.05）.Conclusion Increased thickness of IMTof arteries is one early characteristic of atherosclerosis.Ultrasound can discover neck atherosclerosis early.It is certainly valuable for screening high-risk group of ischemic cerebrovascular as a method of first choice.
