Persistent left superior vena cava is the most common form of anomalous venous drainage involving the superior vena cava, and represents persistence of the left horn of the embryonic sinus venosus, which normally involutes during normal development to become the coronary sinus. Almost always, a persistent left superior vena cava enters the right atrium through the orifice of an enlarged coronary sinus. In this case report of a 60-year-old male cadaver, we describe a persistent left superior vena cava and discuss its embryology and clinical significance.
永存左上腔静脉是涉及上腔静脉的最常见的异常静脉引流形式，代表胚胎静脉窦左角的残留，在正常发育过程中，该左角通常会退化形成冠状窦。几乎总是，永存左上腔静脉通过扩大的冠状窦口进入右心房。在这份关于一名60岁男性尸体的病例报告中，我们描述了永存左上腔静脉，并讨论了其胚胎学和临床意义。
