目的分析冠状动脉瘘的CT血管成像表现.方法回顾性分析12717例行冠状动脉多排螺旋CT血管成像检查病例,其中诊断冠状动脉瘘66例.综合多种后处理图像,记录冠状动脉瘘的起源、瘘口、冠状动脉有无斑块及狭窄.其中14例患者行冠状动脉造影,比较两种检查方法结果的异同.结果 66例冠状动脉瘘中,起源于双侧冠状动脉21例,左冠状动脉26例,右冠状动脉19例;而瘘口在肺动脉41例,左心房10例,右心房8例,左心室4例,冠状静脉2例,右心室1例.14例患者冠状动脉造影显示的瘘管起源和瘘口部位均与多排螺旋CT血管成像一致.31例冠状动脉瘘同时伴冠状动脉斑块形成,其中狭窄程度≥50%者7例.结论双侧冠状动脉起源的冠状动脉瘘并不少见,且瘘口在肺动脉者最多.CT血管成像可作为冠状动脉瘘的首选检查手段,可为该病的治疗提供重要的术前信息.

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.
