64层螺旋CT冠状动脉成像对冠心病的诊断价值

目的:探讨64层螺旋CT冠状动脉成像(64SCTCA)在冠心病诊断中的价值?方法:对118例应用64层螺旋CT扫描的冠状动脉图像(CTA)资料进行回顾性分析?评价?结果:118例64SCTCA中有116例检查成功,冠状动脉主要分支显示良好,达到诊断要求?发现冠状动脉各支病变77例,其中冠状动脉狭窄61例,共82支,有2例为冠状动脉支架置入术后其他冠脉分支发生再狭窄;10例冠状动脉支架放置术后,再狭窄2例;3例冠状动脉搭桥术后,闭塞2支;5例检出心肌桥?51例检出各种斑块80处?结论:64SCTCA可清晰显示冠状动脉狭窄,可以作为冠心病的筛查手段,对冠状动脉支架术后?冠状动脉搭桥术后及冠状动脉斑块评价具有独特的优势,对心肌桥的诊断要优于冠状动脉造影?

The value of 64-slice CT coronary angiography in diagnosis of coronary artery disease

Objective:To evaluate the value of 64-slice CT coronary angiography(64SCTCA)in the diagnosis of coronary heart disease. Methods:With 64SCTCA, the images of 118 cases were analyzed retrospectively. Results:There were 116 of 118 cases showed the main branches of coronary arteries successfully by 64SCTCA examination. 77 cases of coronary artery lesions of various branches were found, including 61 cases totally 82 branches of coronary artery stenosis. There are 2 cases of coronary artery stent placement got the other coronary artery branches postoperative stenosis, 2 branches restenosed in 10 cases of coronary stent placement. 2 branches occluded in 3 cases of coronary artery bypass surgery. 5 cases of myocardial bridge were detected. 80 plaques were detected from 77 cases. Conclusion:64SCTCA showed coronary artery stenosis clearly and could be used to screen for coronary heart disease. It has unique advantage on evaluation of coronary plaque and postoperative situation, such as coronary stent placement and coronary artery bypass surgery. Furthermore, diagnosis of myocardial bridge by 64SCTCA was superior to coronary angiography.
