We aimed to investigate the coronary venous system and its variations by using dual source computed tomography (CT).
Retrospective assessment was carried out on 339 patients who underwent coronary CT angiography using 128-slice dual source CT for suspected coronary artery disease. The examinations were performed according to routine imaging protocols used to evaluate coronary arteries. The coronary venous system was evaluated in each case using maximum intensity projection and volume rendering technique multiplanar reformation reconstructions. In each patient, the presence and calibration of normal anatomy, as well as the variations of the coronary sinus, middle cardiac vein, small cardiac vein, posterior cardiac vein, great cardiac vein, anterior interventricular vein, posterolateral vein, left marginal vein, and anterolateral vein were recorded.
The coronary sinus, middle cardiac vein, great cardiac vein, and anterior interventricular vein were visualized in all of the patients. In all cases, one of the lateral or posterolateral veins of appropriate localization and diameter for cardiac resynchronization therapy was detected. The posterior cardiac vein was visualized in 87% of the cases, the left marginal vein in 87.9%, and the small cardiac vein in 20%. There was no significant difference in the diameters or visibilities of the coronary veins in terms of age.
The coronary venous system and its tributaries may be examined in detail using CT angiography examination performed according to the routine coronary CT angiography protocol used for dual source CT. Dual source CT may be a valuable tool for evaluation of the coronary veins prior to invasive procedures that are directed at the coronary venous system.
我们旨在使用双源 CT 研究冠状动脉静脉系统及其变异。
回顾性分析 339 例疑诊冠心病患者，采用 128 层双源 CT 行冠状动脉 CT 血管造影。检查按照常规冠状动脉成像方案进行。对每位患者均行最大密度投影和容积再现技术多平面重建，评估冠状动脉静脉系统。记录每位患者正常解剖结构的存在和标定情况，以及冠状窦、心中静脉、小心中静脉、心后静脉、心大静脉、前室间静脉、心侧后静脉、心左侧缘静脉和心前外侧静脉的变异情况。
所有患者均显示出冠状窦、心中静脉、心大静脉和前室间静脉。所有患者中均发现一条位于适当部位且直径适合心脏再同步治疗的外侧或心侧后静脉。87%的患者显示心后静脉，87.9%显示心左侧缘静脉，20%显示小心中静脉。静脉直径或可视性与年龄无显著差异。
按照常规冠状动脉 CT 血管造影方案进行双源 CT 冠状动脉 CT 血管造影检查，可详细检查冠状动脉静脉系统及其属支。双源 CT 可能是冠状动脉静脉系统介入治疗前评估冠状动脉静脉的一种有价值的工具。
