摘要
目的评价双源CT冠状动脉成像冠状动脉瘘的检出率和分型诊断,并探讨其在冠状动脉瘘检出中的价值。方法回顾性分析2006年12月至2012年9月南京军区南京总医院,中国医学科学院北京协和医学院北京协和医院,首都医科大学附属安贞医院,江苏省泰州市人民医院连续的48533例双源cT冠状动脉成像资料,分析冠状动脉瘘的检出率、类型及双源CT冠状动脉成像在冠状动脉瘘诊断中的意义。结果共检出102例冠状动脉瘘,发生率0.21%(102/48533)。102例冠状动脉瘘中,冠状动脉肺动脉瘘92例(90.2%,92/102),冠状动脉右心房瘘4例(3.9%,4/102),冠状动脉右心室瘘和冠状动脉左心室瘘各2例(2.0%,2/102)、冠状动脉左心房瘘和冠状动脉心小静脉瘘各1例(1.0%,1/102)。92例冠状动脉肺动脉瘘中,起自双侧冠状动脉46例(50.O%,46/92),左冠状动脉28例(30.4%,28/92),右冠状动脉11例(12.0%,11/92),余7例(7.6%,7/92)同时伴存其他心外血管异常沟通。结论本组冠状动脉瘘的发生率为0.21%,以冠状动脉肺动脉瘘最常见(占90.2%),而来自双侧冠状动脉主肺动脉瘘占50%。双源CT冠状动脉成像可清晰显示这些冠状动脉瘘的类型和异常血管,为诊断和术前评估提供重要信息。
Objective To evaluate the incidence, types and clinical significance of coronary artery fistula (CAF) on CT coronary angiography (CTCA). Methods A total of 48 533 consecutive patients undergoing CTCA at 4 Chinese hospitals were retrospectively analyzed. The incidence, types and clinical significance of CAF were retrospectively summarized. Results One hundred and two patients had CAF with the incidence of 0. 21% ( 102/48 533 ). Among them, coronary to pulmonary artery fistulas were seen in 92 patients (90. 2%, 92/102), coronary to right atrium fistula in 4 (3.9%, 4/102), coronary to right ventricular fistula in 2 (2. 0%, 2/102), coronary to right ventrieular fistula in 2 (2. 0%, 2/102), coronary to left atrium fistula in 1 (1.0% , 1/102) and coronary to small cardiac vein in 1 (1.0% , 1/102). Among 92 coronary to pulmonary artery fistulas, fistulas originated from both coronary arteries in 46 patients (50. 0%, 46/92), from left coronary artery in 28 (30. 4%, 28/92) and right coronary artery in 11 ( 12. 0%, 11/92) and the remaining 7 (7.6%, 7/92) coronary to pulmonary artery fistulas were associated with extracardiac communications. Conclusion The incidence of CAF is 0. 21% with a predominance of coronary to pulmonary artery fistulas (90. 2% ). The most common type of CAF is coronary to pulmonary artery fistulas from both coronary arteries ( 50. 0% ) . Dual source CTCA can clearly visualize types and abnormal vessels so that it plays an important role in the diagnosis and preoperative evaluation of CAF.
