双源CT诊断先天性冠状动脉瘘

目的 观察双源CT在先天性冠状动脉瘘诊断中的应用价值. 方法 使用双源CT机对9例先天性冠状动脉瘘患者进行增强扫描,将获得的数据进行容积再现、多平面重建、最大密度投影、曲面重建,分析冠状动脉走行及心内外结构. 结果 左冠状动脉主干右心室瘘2例;左冠状动脉主干和(或)前降支主肺动脉瘘7例,其中5例合并右冠状动脉主肺动脉瘘. 结论 双源CT冠状动脉造影方便、快捷、无创,可以作为诊断先天性冠状动脉瘘的首选方法.

Dual-source CT in diagnosis of coronary artery fistula

Objective To observe the role of dual-source CT (DSCT) in the diagnosis of coronary artery fistula. Methods Nine patients with coronary artery fistula were examined with dual-source CT coronary artery angiography. Then the source images were post processed using volume rendering (VR), multiple planar reformation (MPR), maximum intensity projection (MIP) and curved planar reformation (CPR), and sequential segmental analysis of the intracardiac and extracardiac anomalies was performed. Results Coronary artery fistula in all the 9 patients were accurately displayed with DSCT, including 2 with left main trunk to right ventricle fistula, 7 with left main trunk and (or) left anterior descending artery to main pulmonary trunk fistula, 5 with complex coronary-pulmonary artery fistula. Conclusion Dual-source CT coronary artery angiography is convenient, fast, non-invasive, and may be the preferable method for diagnosis of coronary artery fistula.
