128层容积CT冠脉造影对壁冠状动脉-心肌桥诊断价值分析

Diagnosis of mural coronary artery wall-myocardial bridge via 128-volume CT coronary angiography

目的探讨128层容积CT冠状动脉造影(128-VCTCA)评价壁冠状动脉-心肌桥(MCA-MB)的形态学特征、准确性及其临床应用价值。方法回顾性分析我院186例可疑冠心病患者,通过CT冠状动脉造影(CTCA)检查,分析MCA-MB冠脉CTA影像学特点。结果 128-VCTCA对MCA-MB的检出率为38.1%。其中,76.8%出现在左前降支,平均长度为(11.76±3.60)mm,心肌桥(MB)平均厚度为(2.90±2.33)mm。128-VCTCA对MCA-MB的检出率高于其他检查。结论128-VCTCA可准确判断MCA-MB的结构特点;128-VCTCA是一种评价MCA-MB可靠的、无创的检查方法。

Objective To explore the 128 volume CT coronary angiography（ 128-VCTCA） evaluation of mural coronary artery,the morphological characteristics of myocardial bridge（ MCA-MB）,accuracy and its clinical value. Methods A retrospective analysis of186 cases of patients with suspected coronary artery disease was performed by CT coronary angiography（ CTCA） inspection,for the analysis of the MCA-MB coronary CTA imaging characteristics. Results CTCA on MCA-MB detection was 38. 1. %,76. 8% of which appear in the left anterior descending branch,the average length of（ 11. 76 ± 3. 60） mm,MB average thickness of（ 2. 90 ± 2. 33）mm. 128-VCTCA of MCA-MB detection rate is higher than other tests. Conclusion 128-VCTCA can accurately judge the structure characteristics of MCA-MB; 128-VCTCA is a noninvasive evaluation of MCA-MB reliable inspection method.
