64层螺旋CT冠状动脉成像对冠状动脉畸形的诊断价值探讨

目的 探讨64层螺旋CT冠状动脉成像对冠状动脉畸形诊断价值.方法 收集2006年8月至2007年5月在我院行64层螺旋CT冠状动脉成像852例患者的影像资料,以冠状动脉造影为金标准,统计冠状动脉畸形的发病率,并分析冠状动脉畸形的CT表现.结果 852例接受64层螺旋CT冠状动脉成像患者中.发现冠状动脉畸形8例,检出率为0.9%.其中冠状动脉异常起源于主动脉3例,左冠状动脉异常起源于肺动脉3例,右冠状动脉-右房瘘1例,冠状动脉瘤1例.结论 64层螺旋CT冠状动脉成像能准确显示冠状动脉畸形的存在以及相互间的解剖关系,可作为冠状动脉畸形的早期筛查手段.

Clinical Value of 64-slice CT Angiography in Detecting Coronary Artery Anomalies

Objective To determine the clinical value of 64-slice computed tomography angiography(CTA) in the diagnosis of coronary artery anomalies.Methods The coronary artery imaging data of 852 patients who underwent 64-slice CTA from July 2006 to May 2007 were retrieved.The imaging features of coronary artery anomalies confirmed by selective coronary angiography were reviewed.Results Eight(0.9%) coronary artery anomalies were found in the patients,which included 3 cases of anomalous aortic origin of coronary arteries,3 cases of anomalous origin of the left main coronary artery from pulmonary artery,1 case of coronary fistula from the right coronary artery to right atrium,and 1 case of coronary aneurysm.Conclusion The 64-slice CTA can detect coronary anomalies and delineate the anatomic relationships among the peripheral structures,which can be considered as an early screening for coronary anomalies.
