摘　　要： 目的 探讨256层CT血管成像（CTA）对冠状动脉瘘（CAF）的诊断价值。方法 回顾性分析CAF 18例，对原始图像进行多平面重组（MPR）、曲面重组（CPR）、最大密度投影（MIP）及容积重建（VR）等后处理。结果 18例CAF中冠状动脉分支血管瘘入肺动脉5例；瘘入冠状静脉窦5例；瘘入右心房3例；瘘入左心房3例；瘘入右心室2例。5例冠状动脉-肺动脉瘘可观察到畸形血管向肺动脉内供血，肺动脉主干内均可见对比剂呈“喷射”或“浓染”征。主肺动脉旁形成丛状或蔓藤状血管网2例。供血动脉区动脉瘤形成3例。结论 256层冠状动脉CTA能准确显示CAF变异血管的解剖细节及血流动力学改变情况，运用多种重建技术能够直观地显示CAF的畸形血管形态。 Objective To investigate the clinical value of 256-slice CT angiography （CTA） in diagnosing coronary artery fistula （CAF）.Methods A total of 18 patients with CAF were analyzed retrospectively. The raw data were transferred to the work station. Image reconstruction techniques were employed, including multiplanar reconstruction （MPR）,curved planar reconstruction {CPR）, maximum intensity projection （MIP） and volume render （VR）.Results Coronary artery angiography showed fistula affluxed to the pulmonary artery in 5 cases,affluxed to the coronary sinus in 5 cases,affluxed to the right atrium in 3 cases,affluxed to the left atrium in 3 cases, affluxed to the right ventricle in 2 cases.The blood flow from abnormal vessels to pulmonary arteries was demonstrated in 5 patients,and ＂injection＂ sign or ＂hyper-density＂ of contrast material in the main pulmonary artery was seen.The tortuous vascular networks on the surface of the main pulmonary artery trunk were seen in 2 cases.Formation of aneurysm was seen in 3 cases.Conclusion 256-slice CTA can precisely show the detailed anatomy variations and heomodynamic information of CAF, and directly display the abnormal vessels with multiple image reconstruction techniques.
