Persistent left superior vena cava (PLSVC) is the most common congenital intrathoracic venous anomaly with significant clinical relevance. In the vast majority of cases, it is asymptomatic and diagnosed after noticing an abnormal course of central venous access device on a routine post-procedure roentgenogram. It may also be accidentally discovered after facing difficulty in accessing the right side of the heart from a left internal jugular vein or left subclavian vein approach, a common site of access while placing cardiac pacemaker and Swan-Ganz catheter, or after a complication associated with hemodialysis (HD) catheter insertion. HD through a catheter in PLSVC has its own set of pitfalls and should be reserved for short-term dialysis at the best. In this case report, we present a scenario where PLSVC was discovered after the placement of a tunneled HD catheter.
永存左上腔静脉（PLSVC）是最常见的先天性胸腔内静脉异常，具有重要的临床意义。在绝大多数情况下，它是无症状的，并且在常规术后 X 光片上发现中心静脉通路装置的异常过程后被诊断出来。在从左侧颈内静脉或左侧锁骨下静脉途径进入右心时遇到困难，或者在放置心脏起搏器和 Swan-Ganz 导管后，或者在与血液透析（HD）导管插入相关的并发症后，也可能偶然发现。通过 PLSVC 的导管进行 HD 有其自身的一系列问题，最好只保留用于短期透析。在本病例报告中，我们介绍了在放置隧道式 HD 导管后发现 PLSVC 的情况。
