摘要
【目的】评价64层螺旋CT在诊断冠状动脉畸形方面的临床应用价值。【方法】对38例冠状动脉畸形的64层螺旋CT资料进行回顾性分析,将原始数据传至工作站,行多平面重建(MPR)、容积再现(VR)、最大密度投影(MIP)和血管探针等后处理。10例同时行传统冠脉造影(CAG),3例行手术。【结果】38例患者畸形血管在CT图像上得以清晰显示。冠状动脉开口起源异常6例,单支冠状动脉畸形2例,冠状动脉瘘2例,冠状动脉肌桥20例,副冠状动脉8例,10例CAG结果9例与CT一致,1例右侧冠状动脉高位开口CAG误诊为缺如,3例手术结果与CT一致。【结论】64层螺旋CT冠状动脉造影清晰显示了畸形血管的起源、行程、终止及腔内情况,可作为冠状动脉畸形首选的检查方法。
[ Objective ] To evaluate the clinical application of 64-slice spiral computed tomography in the diagnosis of coronary artery anomalies （CAAs）. [Methods] The 64-slice spiral computed tomograpby images of 38 patients with CAAs were retrospectively analyzed. The raw data were transferrecl to the work station（vitrcae2 version 3.7.0）, and then multi-planar reconstruction （MPR）, volume render （VR）, maximum intensity projection （MIP）, curved-planar reconstruction （CPR） and blood vessel probe were performed. Ten patients were performed conventional coronary artery anglography （CAG） and 3 patients were performed surgery. [ Results ] The origin and course of anomalous CA in 38 patients were displayed clearly by 64-slice spiral computed tomography. Six patients were anomalous origin of CA think; 2 were single CA anomaly; 2 were the branch of RCA fistula （1 to the pulmonary artery, 1 to the right atrium）; 20 were mural coronary artery; 8 were para coronary artery, which is the branch of arterial conus origins directly from the right coronary sinus. Nine results of the 10 CAG were accordant with CT, 1 high origin of RCA was mistaken for congenital absence in CAG. Three operation results were accordant with CT. [Conclusion] The 64-slice spiral computed tomography displayed the origins, course and the condition of intralumens of CA clearly. It＇s better than CAG on some degree. 64-slice spiral computed tomography could be used as the first choose of imaging tools for suspected CAAs.
