摘　　要：采用血管内超声和冠状动脉造影检查１２例病人发现１０例病人存在硬化性狭窄。４处狭窄呈偏心形，但左冠脉左干末见狭窄病变，造影对斑块的性质观察不清。血管内超声发现６例病人的左冠脉主干存在硬化病变。９处病变为偏心形，５处硬化斑表面粗糙或有裂缝。超声与造影内径的测值相关性良好，γ＝０．８６，Ｐ＜０．００１。３例病人在经皮穿刺冠脉内成形术中用超声进行检测，２例血管病变处为纤维性斑块者，治疗一次成功，另１例钙化性斑块，术后发生血管急性闭塞。血管内超声具有良好的临床应用价值。Twelve cases of coronary heart disease were examined with intravascular ultrasonography and coronary angiography.Ten cases were found to have coronary narrowing, which was of eccentric pattern in 4 branches and no sclerotic narrowing was found in the left main branch of the coronary artery in all the cases with angiography.The nature of the atherosclerotic plaques could not be distinguished with angiography.In travascular ultrasonography revealed sclerotic lesions in the main trunk of the left coronary artery,Nine lesions were of eccentric pattern and the surface of 5 lesions was rough or fissured.The diameter of 20 different positions of the artery measured with intravasculr ultrasonography was similar to that measured with angiography.There was a positive correlation between the 2 methods in the lumen diameter measurement(r=0.86,P<0.01>.Intravascular ultrasonography during PTCA to remove the sclerotic plaque in 3 cases was done.The lesion was a fibrotic plaque and the removal was successful with one operation in 2 cases.In the third one,the lesion was a calcified plaque and acute occlusion of the artery occurred. It is believed that intravascular ultrasonography possesses excellent value for clinical application.
