Malposition of central venous catheters is associated with important and underestimated risks. Although some factors have been related with malposition, its cause is generally not diagnosed, and it seems to have multifactorial origin. We present two cases of central venous catheter malposition due to unusual anatomical causes, diagnosed in the perioperative period. In the first case, superior vena cava agenesis was diagnosed during mitral replacement by sternotomy, which was logically associated with malposition of the inserted central line. The use of catheters and devices through jugular and subclavian veins in patients with this infrequent pathology is associated with important limitations and serious potential complications. In the second case, an undiagnosed goiter causes bilateral and simultaneous malpositioning of two inserted central venous catheters, in the context of an emergency situation, in both internal jugular veins.

Palabras llave : central venous catheter; malposition; absent right superior vena cava; goiter.
