摘　　要：目的 研究冠状动脉旁路移植术病人颈动脉粥样硬化与冠状动脉粥样硬化的关系．探讨术前颈动脉超声检查的临床意义。方法 对52例拟行冠状动脉旁路移植术病人行颈动脉超声检查，依冠状动脉造影结果分为冠状动脉单支病变组、双支病变组及多支病变组，同时选取冠状动脉造影阴性者30例作为对照组，比较各组间颈动脉内膜-中层厚度、斑块积分以及斑块检出率。结果 各组间颈动脉内膜-中层厚度、斑块积分及斑块检出率的差异均有统计学意义（F=4．27、15．58，q=2．93～9．27；χ^2=12．38～34．72，P〈0．05、0．01）。结论 冠心病与颈动脉粥样硬化存在明显的相关性，术前超声检测颈动脉能够预测冠状动脉病变的严重程度。Objective To evaluate the clinical significance of carotid ultrasonography by studying the relationship of the common carotid artery atherosclerosis with coronary heart disease. Methods Carotid ultrasonography was performed in 52 patients with coronary heart disease （CHD） before coronary artery bypass graft and 30 normal controls. According to the results of angiography, the CHD patients were subdivided into the single-vessel disease; the double vessel disease, and the multi vessel. The thickness ofintimia media, existence of the carotid plaque and the plaque score were compared. Results The thickness of intimia-media and the existence of the carotid plaque and the plaque score were significantly different among the three groups （F=4.27,15.58,q=2.93-9.27;χ^2=12.38-34. 72,P〈0. 05,0. 01）. Conclusion There is a close relationship between the carotid athe-rosclerosis and coronary atherosclerosis, the coronary artery lesion can be predicted by pre-operative carotid ultrasonography.
