Abstract:
Objective To analyzed the computed tomography angiography (CTA) features of the coronary artery fistulas. Methods Sixty-six coronary artery fistulas were diagnosed out of 12 717 patients underwent the coronary artery multiple detector CTA examination. The origin and drainage site of the coronary artery fistulas and the plaque and stenosis of the coronary artery were observed by post-processing analysis on various images. Coronary artery angiography was performed in 14 out of 66 coronary artery fistulas patients. Results Coronary artery fistulas arose from bilateral coronary artery system in 21 cases, from left coronary artery in 26 cases and from right coronary artery in 19 cases. The majority of coronary artery fistulas entered into pulmonary artery (41 cases). The rest drainage sites included left atrium (10 cases), right atrium (8 cases),left ventricle (4 cases), coronary sinus (2 cases) and right ventricle (1 case). The findings of CTA and coronary artery angiography were consistent in 14 patients with DSA examination. Coronary artery plagues were evidenced in 31 cases and stenosis was greater than 50% in 7 coronary artery fistulas patients. Conclusions Multiple coronary artery fistulas are not rare, and pulmonary artery is the most frequent drainage site. When suspecting the coronary artery fistulas, coronary artery CTA can be the first choice of diagnose. CTA can supply adequate information for therapy.
