An absent right superior vena cava associated with a persistent left superior vena cava (PLSVC) is a rare and generally asymptomatic congenital malformation. It is usually discovered incidentally during a pacemaker (PM) implantation. We report here a successful PM implantation using a left subclavian approach through the coronari sinus via a PLSVC, with a 2-year follow-up showing a still appropriate function of the device. We discuss the clinical usefulness of peripheral phlebography in the operating room for delineating precisely the venous anatomy, as well as the role of shaped stylets and active fixation leads to overcome technical difficulties.
右头臂静脉缺如合并永存左上腔静脉（PLSVC）是一种罕见且通常无症状的先天性畸形。它通常在起搏器（PM）植入过程中偶然发现。我们在此报告一例通过PLSVC经冠状窦采用左锁骨下途径成功植入PM的病例，2年随访显示该装置功能仍然正常。我们讨论了术中外周静脉造影在精确描绘静脉解剖结构方面的临床实用性，以及塑形探条和主动固定导线在克服技术困难方面的作用。
