摘要 目的:探讨64层螺旋CT冠状动脉成像对心肌桥(MB)的诊断及临床价值。方法:统计在医院健康查体或临床怀疑冠心病的217例患者,均行64-MSCTA检查,将所有数据传至工作站进行重建和后处理,观察患者有无MB,并测量其长度、厚度以及壁冠状动脉狭窄程度等。结果:217例患者中发现心肌桥61例(占28%)共63支,左前降支近段发生率最高,为43支(占68%);MB合并粥样硬化者28支,其斑块位于MB近端者20支(占71%)。结论:64层螺旋CT可以清晰显示MB及其分型,为临床判断心肌缺血的可能原因及是否进行干预治疗提供依据。 Objective: To assess the clinical diagnosis of myocardial bridge (MB) by 64-slice CT coronary angiography. Methods: Two hundred and seventeen subjects (129 males, 88 females), under the healthy examination or suspected coronary heart disease, were performed 64-slice CT from May 2009 to January 2011 in our hospital. The subjects were 32 to 81 years old, and the mean age was 59. All the data were transformed to the workstation, then reconstructed and post-processed. If MB was detected, its length, thickness and the extent of coronary artery stenosis were measured, respectively. Results: Sixty one myocardial bridges were found in 217 cases (28%). The proximal left anterior descending artery was the most frequent location for MB (41 in 63). 28 MBs were combined with coronary atherosclerosis, in which 71% (20 in 28) atherosclerotic plaques were located in the proximal MBs. Conclusion: The MBs could be clearly detected using 64-slice CT coronary angiography, and it play a potential roll in the clinical diagnosis and therapy of myocardial ischemia.
