摘要
目的探讨双源CT血管成像(DSCTA)在先天性冠状动脉瘘(CAF)诊断中的应用价值。方法分析68例接受回顾性心电门控冠状动脉DSCTA的CAF患者影像资料,进行容积再现(VR)、多平面重建(MPR)、最大密度投影(MIP)、曲面重建(CPR)后确定诊断。结果 68例CAF中,瘘口位于肺动脉18例,右心室31例,左心室16例,上腔静脉3例;CAF瘘支血管起源右冠状动脉33例,左冠状动脉30例,左、右冠状动脉双侧起源5例。瘘支血管影像表现为增宽、迂曲28例,扩张、动脉瘤26例,迂曲的血管网18例。结论冠状动脉DSCTA方便、快捷、无创,可以作为诊断先天性冠状动脉瘘的首选方法。
Objective To study the value of dual-source CT angiography （DSCTA） in the diagnosis of congenital coronary artery fistula （CAF）. Methods Images of 68 CAF patients who underwent DSCTA using retrospective ECG-gating were analyzed, volume rendering （VR）, multiple planar reformation （MPR）, maximum intensity projection （MIP） and curved planar reformation （CPR） were performed for diagnosis of CAF. Results CAF entered into pulmonary artery （18 cases）, right ventricle （31 cases）, left ventricle （16 cases） and superior vena cava （3 cases）. The CAF arose from right coronary artery in 33 cases, from left corotlary artery in 30 cases and from bilateral coronary artery system in 5 cases. The involved arteries manifested as dilatation and anfractuosities in 28 cases, dilatation and aneurysm in 26 cases, tortuous vascular net in 18 cases. Conclusion The coronary artery DSCTA is a convenient, fast, and non-invasive method for CAF, and it may be the preferable method for the diagnosis of CAF.
