To obtain the coronary artery and coronary sinus (CS) and its tributaries imaging with multislice computed tomography (MSCT), measure the distance between coronary artery and CS and its tributaries and analyze their spatial relationships.
The MSCT scans of 117 patients (67 men, 50 women, age 56 +/- 10 years) were obtained, 3D image reconstructed and the vessels courses evaluated. The concomitant distances and spatial relationships of the vessels were determined.
Right coronary artery domination was found in 107 cases (91.4%), left coronary artery domination in 7 cases (6.0%), and co-domination in 3 cases (2.6%). Left circumflex artery (LCX) was concomitant with CS or the great cardiac vein (GCV) in 81 cases (69.2%), intersected with left posterior vein in 62 cases (53.0%) and with middle cardiac vein (MCV) in 5 cases (4.3%), respectively. The dominant coronary artery branched out into the posterior descending artery (PDA) and the left posterior artery (LPA) in 112 cases (95.7%). PDA was concomitant with MCV in 93 cases (79.5%) and intersected with MCV in 44 cases (37.6%). LPA was intersected with MCV in 106 cases (90.6%), and concomitant with CS in 50 cases (42.7%).
MSCT is a reliable tool to visualize the relationship between coronary artery and CS and its tributaries. Owing to the multiple possibilities inherent to this technique, MSCT has broad potential for more clinical use.
利用多层螺旋计算机断层扫描（MSCT）获取冠状动脉及冠状窦（CS）及其属支的影像，测量冠状动脉与CS及其属支之间的距离，并分析它们的空间关系。
获取117例患者（男67例，女50例，年龄56±10岁）的MSCT扫描图像，进行三维图像重建并评估血管走行。确定血管的伴随距离及空间关系。
右冠状动脉优势型107例（91.4%），左冠状动脉优势型7例（6.0%），均衡型3例（2.6%）。左旋支（LCX）与CS或大心静脉（GCV）伴行81例（69.2%），与左后静脉相交62例（53.0%），与心中静脉（MCV）相交5例（4.3%）。优势冠状动脉分支为后降支（PDA）和左后动脉（LPA）112例（95.7%）。PDA与MCV伴行93例（79.5%），与MCV相交44例（37.6%）。LPA与MCV相交106例（90.6%），与CS伴行50例（42.7%）。
MSCT是显示冠状动脉与CS及其属支关系的可靠工具。由于该技术固有的多种可能性，MSCT在更多临床应用方面具有广阔潜力。
