The venous anomaly of a persistent left superior vena cava (PLSVC) affects 0.3%-0.5% of the general population. PLSVC with absent right superior vena cava, also termed as "isolated PLSVC," is an extremely rare venous anomaly. Almost half of the patients with isolated PLSVC have cardiac anomalies in the form of atrial septal defect, endocardial cushion defects, or tetralogy of Fallot. Isolated PLSVC is usually innocuous. Its discovery, however, has important clinical implications. It can pose clinical difficulties with central venous access, cardiothoracic surgeries, and pacemaker implantation. When it drains to the left atrium, it may create a right to left shunt. In this case report, we present the incidental finding of isolated PLSVC in a patient who underwent aortic valve replacement. Awareness about this condition and its variations is important to avoid complications.
持续性左上腔静脉（PLSVC）的静脉异常在普通人群中的发生率为0.3%-0.5%。无右上腔静脉的PLSVC，也称为“孤立性PLSVC”，是一种极其罕见的静脉异常。几乎一半的孤立性PLSVC患者存在房间隔缺损、心内膜垫缺损或法洛四联症等心脏异常。孤立性PLSVC通常无害。然而，其发现具有重要的临床意义。它可能在中心静脉通路、心胸外科手术和起搏器植入方面带来临床困难。当它引流至左心房时，可能会形成右向左分流。在本病例报告中，我们呈现了一名接受主动脉瓣置换术患者中偶然发现的孤立性PLSVC。了解这种情况及其变异对于避免并发症很重要。
