The placement of central catheters through the subclavian and jugular venous path can be complicated by the cannulation of an artery or an aberrant venous path. The most frequent anomaly of the embryological development of the caval vein is the persistence of the left superior vena cava (LSVC). The implantation of catheters in the LSVC can be suspected by its anomalous route in thorax radiography. Gasometry and the pressure curve of the vessel make it possible to rule out an arterial catheterisation. Diagnostic confirmation is obtained through angiography, echocardiography, computerised tomography or cardiac resonance. The doctor who regularly implants central venous catheters must be familiar with the anatomy of the venous system and its variants and anomalies, since their presence might influence the handling of the patient.

Palabras clave : Persistence of left superior vena cava; Anomalous systemic venous return; Central venous catheter; Swan-Ganz catheter.
