Persistant left superior vena cava is a rare systemic venous anomaly that can be associated with agenesis of the right superior vena cava. It is usually assymptomatic and discovered incidentally during surgery or other procedures. The authors present the case of a 72-year-old male submitted to an aortic valve replacement surgery. After sternotomy, persistant left superior vena cava and absence of the right superior vena cava were identified. The patient developed complete atrioventricular block after surgery, requiring the implantation of a definitive cardiac pacemaker through the brachiocephalic vein and coronary sinus. This case highlights and ilustrates the clinical implications of the described systemic venous anomalies, discussing the necessary management both in the perioperative and intraoperative periods.
永存左上腔静脉是一种罕见的体静脉异常，可与右上腔静脉缺如相关。它通常无症状，在手术或其他操作过程中偶然发现。作者报告了一例72岁男性接受主动脉瓣置换手术的病例。胸骨切开术后，发现永存左上腔静脉且右上腔静脉缺如。患者术后发生完全性房室传导阻滞，需要通过头臂静脉和冠状窦植入永久性心脏起搏器。本病例突出并说明了所描述的体静脉异常的临床意义，讨论了围手术期和手术期的必要管理。
