Purpose To explore a coronary artery fistula to improve (CAF), while diagnosis rates and reduce patient suffering, to reduce the financial burden on the patient's screening method. Materials and Methods angiography or surgery as the gold standard for diagnosis of CAF, retrospective analysis in January 2006-2010 1 month,27 cases ultrasound diagnosis of patients with CAF, and 21 cases of ultrasound diagnosis of patients suspected CAF, this 48were carried out in a 64-row CT coronary angiography imaging examination and inspection of these 48 patients the detection rates of ultrasound and CT were compared (Statistical Methods: t test, P＜0.05, statistically significant). Results 48 patients angiography in the diagnosis CAF 37 cases (7 cases had surgery) ,Interventricular septum defect 1 case (had surgery), running variations of patent ductus arteriosus 1 case (had surgery), 9 patients were normal;64row CT angiography CAF 37 cases (including one case of imaging and course variation of patent ductus arteriosus), Interventricular septum defect 1 case (had surgery), 10 cases were normal. Conclusion Ultrasound diagnosis of the diagnosis on the high rate of CAF can be used as a screening means, 64-row CT angiography diagnosis rate almost similar to do with the ultrasound screening, with 64-row CT to further verify and improve the diagnostic rate in the same time can bepatients to relieve suffering and economic burden.%目的:探讨一种在提高冠状动脉瘘(CAF)诊断率的同时,减少患者痛苦、减轻患者经济负担的检查方法.材料和方法:以血管造影或手术作为诊断CAF的金标准,回顾性分析2006-01～2010-01 27例超声诊断为CAF的患者和21例超声诊断为可疑CAF的患者,这48名患者均进行了64排CT冠状动脉成像检查和血管造影检查,将48例患者超声和CT的检测率进行对比分析(统计方法采用t检验,P<0.05,有统计学意义).结果:48例患者血管造影诊断CAF37例(7例已手术),室间隔肌部缺损1例(已手术),走行变异动脉导管未闭1例(已手术),9例未见异常;64排CT血管成像诊断CAF37例(其中1例血管造影诊断为走行变异动脉导管未闭),室间隔肌部缺损1例(已手术),10例未见异常.结论:超声对CAF的诊断率较高,可以作为一种筛选的手段,64排CT诊断率几乎与血管造影相仿,用超声做筛选,用64排CT进一步印证在提高诊断率的同时可以减轻患者痛苦和经济负担.
