Persistent left superior vena cava (PLSVC) is a common congenital venous anomaly, usually associated with other congenital heart diseases (12%). Its incidence in the general population is 0.5%. In cardiac surgery patients, it is suspected when using the left subclavian vein or left internal jugular vein for central venous catheter or hemodialysis catheter placement. Transthoracic ultrasound exam is useful in confirming the position of catheters in the venous system by injecting a 5% glucose solution that can be visualized in the right atrium after administration through the catheter. Hemodialysis catheters can be inserted in the PLSVC with good catheter function and no major risk in increase of complications.
永存左上腔静脉（PLSVC）是一种常见的先天性静脉异常，通常与其他先天性心脏病相关（12%）。其在普通人群中的发病率为0.5%。在心脏手术患者中，当使用左锁骨下静脉或左颈内静脉进行中心静脉导管或血液透析导管置入时，会怀疑存在该异常。经胸超声检查通过注入5%葡萄糖溶液来确认导管在静脉系统中的位置，注入后可在右心房中看到该溶液。血液透析导管可插入永存左上腔静脉，导管功能良好，且并发症增加的风险不大。
