冠状动脉CT成像检查对心肌桥-壁冠状动脉的诊断价值

目的探讨冠状动脉CT成像（CTA）在心肌桥-壁冠状动脉临床诊断中的价值。方法采用64层螺旋CT对327例患者行冠状动脉CTA检查,观察有无心肌桥,并对异常段壁冠状动脉进行狭窄评估。心肌桥病例均行冠状动脉造影检查并对比。结果 327例患者共发现57例66段心肌桥,其平均长度为（4.72±0.93）mm,平均厚度为（2.04±0.62）mm,壁冠状动脉的狭窄程度为（33±20）%。对比冠状动脉造影检查共发现29例35段心肌桥,两者差异有统计学意义（P〈0.05）。结论冠状动脉CTA检查可以清晰显示心肌桥和壁冠状动脉,与传统造影方法相比对临床诊断有重要意义。

Diagnostic Value of CT Angiography in Myocardial Bridge and Mural Coronary Artery

Objective To discuss the clinical value of CT angiography（CTA） in diagnosis of myocardial bridge and mural coronary artery.Methods Three hundred twenty-seven patients were performed 64 slices CT angiography to observe myocardial bridge,and evaluate the stenosis of mural coronary artery.All cases with myocardial bridge received coronary arteriongraphy and comparison.Results Fifty-seven cases with 66 myocardial bridge segments were found,with mean length（4.72±0.93） mm,mean thickness（2.04±0.62） mm,the mean stenosis of mural coronary artery was（33±20）%.Twenty-nine cases with 35 myocardial bridge segments were found by coronary arteriongraphy,the difference between them has statistical significance（P0.05）.Conclusion CTA can clearly show myocardial bridge and mural coronary artery,and it has important significance in clinical diagnosis compared with traditional coronary arteriongraphy.
