双源CT血管成像对成人冠状动脉瘘的诊断价值

摘要

ObjectiveTo study the effectiveness of application of dual-source computed tomography angiography (DSCTA) in the diagnosis of coronary artery fistula (CAF) in adults.Methods DSCTA images of 16648 patients who had been treated in the hospital from November 2011 to July 2015 were analyzed retrospectively. The DSCTA source imaging data were post-processing reconstructed by volume rendering (VR), multiple planar reformation (MPR), maximum intensity projection (MIP) and curved planar reformation (CPR). The origin, course and the site of CAF were analyzed.ResultsAmong the 16648 patients, 44 patients were diagnosed with CAFs by DSCTA, including 41 patients with right cardiac chamber fistulas and 3 with left cardiac chamber fistulas. Among the 44 patients, 32 patients had one traceable ifstula and the remaining 12 patients were shown to have two or three ifstula vessels. ConclusionCoronary CTA demonstrates itself as a useful, noninvasive and easy-to-operate imaging modality and should be taken as a ifrst choice for the detection of CAF.%目的：评价双源CT血管成像（DSCTA）对成人冠状动脉瘘（CAF）的诊断价值。方法选取本院2011年11月~2015年7月间收治的16648例行冠状动脉DSCTA的受检者作为研究对象，通过容积再现（VR）、多平面重组（MPR）、最大密度投影（MIP）、曲面重组（CPR）等方法对其图像进行后处理，分析CAF的起源、走行及引流部位。结果16648例患者中，共诊断CAF44例，其中右心系统瘘41例，左心系统瘘3例；单瘘口43例，多瘘口1例；单一血管供血32例，多个血管供血12例。结论冠状动脉双源CT血管成像简单、安全、无创，可作为CAF诊断的首选方法。
