title: [Persistence of the left superior vena cava discovered during the implantation of a hemodialysis catheter].
abstract: A persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly. It is a persistent remnant of the left anterior cardinal vein that usually disappears in early embryological development as a result of compression between the left atrium and the hilum of the left lung. If it is not associated with other congenital cardiac anomalies it is usually asymptomatic but has important clinical implications in some situations. In this article, we describe a patient with bilateral SVC identified on a chest radiograph by a haemodialysis central venous catheter passing through it.
