颈动脉粥样硬化与肾动脉狭窄的相关性研究

Correlation of carotid artery atherosclerosis with renal artery stenosis assessed by ultrasound

目的 探讨冠状动脉粥样硬化患者颈动脉粥样硬化与肾动脉狭窄的相关性。方法 对 5 4例冠状动脉造影患者的颈动脉行超声检查 ,并对照其肾动脉及冠状动脉血管造影检查结果 ,经单因素 χ2检验 ,研究其相关性。结果 冠状动脉粥样硬化患者伴颈动脉粥样硬化者肾动脉狭窄的发病率高于无颈动脉粥样硬化者 ,而且 ,颈动脉粥样硬化越重 ,肾动脉狭窄的发病率越高 ,狭窄程度也越重。

Objective To study the correlation of carotid artery atherosclerosis with renal artery stenosis assessed by ultrasound in patients undergoing routine cardiac catheterization.Methods Analyse the ultrasonographic features of carotid artery atherosclerosis, angiographic features of renal artery stenosis and coronary artery lesions in patients undergoing routine cardiac catheterization, then assess the correlation between them by χ 2 test.Results Among the patients suffering from carotid artery atherosclerosis, the prevalence of renal artery stenosis was higher than those without carotid artery atherosclerosis, moreover, the severity of renal artery stenosis was correlated closely with the extent of carotid artery atherosclerosis.Conclusions Carotid artery atherosclerosisis is correlated closely with renal artery stenosis.
