摘　　要：目的评价双源CT冠状动脉成像技术对冠状动脉瘘的观察效果,研究其对冠状动脉瘘的诊断价值。方法回顾性分析15例冠状动脉瘘患者双源CT冠状动脉成像检查结果,原始数据应用MIP、MPR、CPR、VR后处理技术观察冠状动脉的形态。结果 15例冠状动脉瘘中,4例为右冠状动脉-右心室瘘;3例为右冠状动脉-肺动脉瘘;3例为左冠状动脉-右心室瘘;5例为左冠状动脉-肺动脉瘘。2例合并房间隔缺损,1例合并室间隔缺损及动脉导管未闭,1例合并法乐氏四联征,1例合并肺动脉瓣狭窄。结论 DSCT冠状动脉成像可以准确显示冠状动脉瘘的引流位置及瘘道大小,可观察心内结构及合并畸形,可作为临床诊断冠状动脉瘘的一种安全无创的影像学检查方法。Objective To investigate coronary artery fistulas by dual-source CT angiography(DSCTA).Methods A total of 15 cases of coronary artery fistulas patients underwent DSCTA,and MIP,MPR,CPR,and VR were performed and showed the configuration of anomaly coronary artery.Results A total of 15 cases of coronary artery fistula included right coronary artery-right ventricle fistula(n=4),right coronary arterypulmonary artery fistula(n=3),left coronary artery-right ventricle fistula(n=3),left coronary artery-pulmonary artery fistula(n=5),2 cases with atrial septal defect,1 cases with ventricular septal defect and patent ductus arteriosus,1 cases with tetralogy of Fallot syndrome,1 case with pulmonary valve stenosis.Conclusion DSCT coronary angiography can show the location and size of the coronary artery fistula and observe the cardiac inner structure and deformity which is very important for operation therapy,DSCT can be the a safe and noninvasive imaging examination method of coronary artery fistula.
