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。
Objective To investigate the value of coronary artery tomography (CTA) in the clinical diagnosis of myocardial bridge-wall coronary arteries. Methods Totally 327 patients underwent CTA with 64-slice spiral CT to observe the presence or absence of myocardial bridge and evaluate the stenosis of abnormal coronary artery. Myocardial bridge cases underwent coronary angiography and contrast. Results A total of 66 66 cases of myocardial bridge were found in 327 patients. The average length was (4.72 ± 0.93) mm, the mean thickness was (2.04 ± 0.62) mm, and the degree of stenosis of the wall coronary artery was (33 ± 20)%. A total of 29 cases of 35 myocardial bridges were found in the contrast coronary angiography, the difference was statistically significant (P <0.05). Conclusion Coronary CTA can clearly show the myocardial bridge and the wall coronary arteries, compared with the traditional imaging methods for clinical diagnosis of great significance.
