为了分析64层螺旋CT(64-MDCT)对成年人冠状动脉变异的表现特征,我们回顾性收集64-MDCT冠状动脉变异患者34例,男性26例,女性8例,平均年龄53.4岁(30~72岁)。对原始数据分别采用多平面重建(MPR)法,最大密度投影(MIP)法,表面阴影遮盖(SSD)法,容积再现(VRT)法进行图像重建。34例冠状动脉变异均清晰显示,右冠状动脉开口于左冠状窦4例,副右冠状窦8例,左前降支和左回旋支分别独立开口于左冠状窦3例,左冠状动脉开口于肺动脉与左冠状动脉高位各1例,心肌桥10例(左前降支9例,左回旋支1例),右冠状动脉-右心房瘘1例,左冠状动脉-右心室瘘1例,过优势型左冠状动脉3例,冠状动脉瘤2例。因而,64-MDCT可以清晰地、直观地显示变异冠状动脉起源、路径及腔内情况,是一种很好的冠状动脉检查方法。
To analyze the features of 64-MDCT in adult coronary artery disease, we retrospectively collected 34 patients with 64-MDCT coronary artery disease, including 26 males and 8 females, with an average age of 53.4 years (range 30 ~ 72 years old). The original data were reconstructed by multi-plane reconstruction (MPR) method, maximum density projection (MIP) method, surface shadowing (SSD) method and volume reproduction method (VRT) 34 cases of coronary artery variation were clearly showed that the right coronary artery in the left coronary sinus in 4 cases, 8 cases of the right coronary artery, left anterior descending artery and left circumflex artery were independently open in the left coronary sinus in 3 cases, the left coronary artery in the pulmonary artery And left coronary artery in 1 case, myocardial bridge in 10 cases (left anterior descending artery in 9 cases, left circumflex artery in 1 case), right coronary artery - right atrial fistula in 1 case, left coronary artery - right ventricular fistula in 1 case, over dominant type 3 cases of left coronary artery, 2 cases of coronary aneurysm. Thus, 64-MDCT can clearly and intuitively show the origin of coronary artery variation, path and intracavitary conditions, is a good method of coronary artery examination.
