Although persistent left superior vena cava (PLSVC) is rare, it is the most common thoracic venous anomaly. The prevalence of PLSVC is 0.3 % in a general population and 10 % in patients with congenital heart disease. Diagnosis of PLSVC is usually incidental during cardiovascular imaging or surgery. Although PLSVC is usually not associated with any negative hemodynamic effect, it is important to be aware of its existence, since it may cause problems in central venous catheterization, pacemaker implantation and cardiopulmonary bypass. The overall proportion of absent right superior vena cava in patients with PLSVC is approximately 20 %. If PLSVC is associated with absence of the right superior vena cava, the coronary sinus may become gigantic due to excessive inflow. Herein, we report a case of PLSVC complicated by the absence of a right superior vena cava resulting in a giant coronary sinus.
尽管永存左上腔静脉（PLSVC）较为罕见，但它是最常见的胸部静脉异常。在普通人群中，PLSVC的患病率为0.3%，而在先天性心脏病患者中为10%。PLSVC的诊断通常在心血管成像或手术过程中偶然发现。虽然PLSVC通常不会产生任何负面的血流动力学影响，但了解其存在很重要，因为它可能在中心静脉置管、起搏器植入和体外循环中引发问题。PLSVC患者中右上腔静脉缺如的总体比例约为20%。如果PLSVC与右上腔静脉缺如相关，由于血流量过多，冠状窦可能会变得巨大。在此，我们报告一例PLSVC合并右上腔静脉缺如导致巨大冠状窦的病例。
