The aim of this study was to evaluate the incidence of coronary-to-bronchial artery fistula (CBF) and clinical significance in 1300 patients examined with 64-multidetector computed tomography (MDCT) coronary angiography.
One thousand three hundred ten patients underwent coronary MDCT for atypical chest pain or screening. Volume-rendering and multiplanar reconstruction images were reviewed, and subsequent cineangiographies were compared.
Eight cases of CBF were detected-6 originated from the left circumflex artery, and 2 originated from the right coronary artery. A hypertrophied anomalous branch of left circumflex artery was observed in 1 case, and underlying bronchiectasis was noted. Seven cases had a thin-wall communicating vessel. Subsequent cineangiography revealed identical appearance with MDCT reconstruction images.
The incidence of CBF (0.61%) in this study is similar to those of a few cineangiographic studies in the literature. Our study showed that 64-MDCT coronary angiography is an accurate and noninvasive tool for detection of CBF.
本研究旨在评估1300例行64层螺旋计算机断层扫描（MDCT）冠状动脉造影检查患者的冠状动脉-支气管动脉瘘（CBF）发生率及其临床意义。
1310例患者因非典型胸痛或筛查接受冠状动脉MDCT检查。回顾容积再现和多平面重建图像，并与随后的血管造影进行比较。
检测到8例CBF，6例起源于左旋支动脉，2例起源于右冠状动脉。1例观察到左旋支动脉异常分支增粗，并伴有支气管扩张。7例有薄壁交通血管。随后的血管造影显示与MDCT重建图像表现一致。
本研究中CBF的发生率（0.61%）与文献中少数血管造影研究的结果相似。我们的研究表明，64层MDCT冠状动脉造影是检测CBF的准确且无创的工具。
