A heart with a persistent left superior vena cava was found in a 72 year old man during routine dissection. The right superior vena cava was absent. The right brachiocephalic vein crossed over the aortic arch and its branches to the left side of the heart. This variation reportedly occurs in about 0.16% of humans. The azygos vein was, as a result, also left sided with a hemiazygos vein on the right side. The left superior vena cava drained into a channel contained with the posterior wall of the left atrium of the heart above, and parallel with the coronary sinus. The channel of the left superior vena cava opened into the right atrium above the opening of the coronary sinus. The coronary sinus may have been doubled during embryonic development. The two vessels were joined by a small connecting vessel.
在一名72岁男性的常规解剖中发现一颗存在永存左上腔静脉的心脏。右上腔静脉缺如。右头臂静脉越过主动脉弓及其分支至心脏左侧。据报道，这种变异在约0.16%的人群中出现。因此，奇静脉也位于左侧，右侧有半奇静脉。左上腔静脉引流至心脏左心房后壁上方并与冠状窦平行的一个通道。左上腔静脉通道开口于冠状窦开口上方的右心房。冠状窦在胚胎发育过程中可能出现重复。这两条血管由一条小连接血管相连。
