OBJECTIVE
A routine dissection of the cadaver of a 67-year-old man revealed a very rare morphological variant of the great cardiac vein (GCV).
PRESENTATION
The vein originated in the upper third of the anterior interventricular sulcus, crossed the anterior interventricular artery superficially, ran beneath the circumflex artery, crossed the transverse pericardial sinus, and drained directly into the superior vena cava.
CONCLUSION
This variant of the GCV is interesting due to its rarity. It is important to know about it for procedures that require venous access such as coronary surgery requiring retrograde cardioplegia, surgical ablation of aberrant conducting pathways, pacemaker insertion, and valve surgery.
目的
对一名 67 岁男性尸体进行常规解剖，发现了一种非常罕见的大心静脉（GCV）形态变异。
表现
该静脉起源于前室间沟的上三分之一，浅行穿过前室间动脉，走行于回旋支动脉下方，穿过横心包窦，直接注入上腔静脉。
结论
这种 GCV 变异由于其罕见性而引人注目。对于需要静脉通路的手术（如需要逆行心麻痹的冠状动脉手术、异常传导途径的手术消融、起搏器植入和瓣膜手术），了解这种变异很重要。
