目的 评价双源冠状动脉CTA对 先天性冠状动脉-肺动脉瘘(congenital c o r o n a r y a r t e r y - p u l m o n a r y fistula,CCPF)的诊断价值，从而提高CPF 的检出率。方法 回顾性分析我院自2014 年8月至2016年7月行双源CT冠脉成像的受 检者共3500例，全部病例均行多平面重建 (multi-planar reconstrcution,MPR)、 容积再现(volume rendering,VR)、 最大密度投影 ( m a x i m a l i n t e n s i t y projection, MIP)及冠脉管腔评估等后处 理。结果 收集的3500例受检者中共发现 CPF9例，其中包括4例左、右冠状动脉-肺 动脉瘘，2例右冠状动脉-肺动脉瘘，2例 左前降支-肺动脉瘘，1例右冠状动脉圆锥 支-肺动脉瘘。结论 双源冠脉CTA能够准 确诊断CPF，可作为CPF诊断的首选方法。

Objective To evaluate the diagnositic value of dual-source coronary CTA in congenital coronary artery-pulmonary fistula (CCPF). Methods The imaging meterials of 3500 patients from August 2014 to July 2016 who undertaken dual-source coronary CTA examination were analyzed retrospectively. The dual-source coronary CTA imaging data were post-processing reconstructed by multi-planar reconstrcution(MPR), maximal intensity projection(MIP), volume rendering(VR) and vascular evaluation. Results 9 congenital coronary artery-pulmonary fistula (CCPF) patients were found in 3500 patients, including 4 patients with left/right coronary artery-pulmonary fistula, 2 patients with right coronary artery-pulmonary fistula, 2 patients with left anterior descending artery--pulmonary fistula and 1 patient with right conus branch artery- -pulmonary fistula. Conclusion Dual-source coronary CTA accurately diagnose the congenital coronary artery-pulmonary fistula and should be taken as a first method to exam congenital coronary artery-pulmonary fistula.
