The coronary sinus is an anatomic landmark and conduit for many diagnostic and therapeutic procedures. We studied 40 human and 40 canine coronary sinuses of the heart in order to ascertain various functional anatomic features of the coronary sinus and its tributaries. We performed a comparative analysis of human and canine cardiac veins. We also studied the formation, tributaries, length, diameter and the ostium of the coronary sinus. The tributaries of the coronary sinus were highly variable in human and dog. The main and constantly present tributaries of both the human and canine coronary sinus were the great and the middle cardiac veins. We also found a rare case of a small cardiac vein connecting two cardiac venous systems--the coronary sinus and its tributaries and the anterior cardiac veins. In two cases we found a common trunk of the small cardiac vein and middle cardiac vein which opened into the coronary sinus. An intramyocardial course of the anterior interventricular vein was found in 2 cases and in 1 case the vein curved twice around the anterior interventricular branch of the left coronary artery. The Thebesian and Vieussens valves and ostial valves of other cardiac veins were also found.
冠状窦是许多诊断和治疗操作的解剖学标志和管道。我们研究了40例人类心脏和40例犬类心脏的冠状窦，以确定冠状窦及其属支的各种功能解剖特征。我们对人类和犬类心脏静脉进行了比较分析。我们还研究了冠状窦的形成、属支、长度、直径和开口。冠状窦的属支在人类和犬类中差异很大。人类和犬类冠状窦主要且恒定存在的属支是心大静脉和心中静脉。我们还发现了1例罕见的小静脉连接两个心脏静脉系统的情况——冠状窦及其属支和心前静脉。在2例中，我们发现小静脉和心中静脉有共同干并开口于冠状窦。在2例中发现前室间静脉有心肌内走行，1例中该静脉围绕左冠状动脉前室间支弯曲了两次。还发现了心最小静脉、 Vieussens瓣以及其他心脏静脉的开口瓣膜。
