Dislocation of central venous catheters in paediatric patients.

Children have limited venous access possibilities; therefore, when long-term therapy is necessary, it is better to place a catheter in a central vein. The Port catheter, totally implanted, is less exposed to the risk of infection and permits a normal life. However, there is the possibility of the displacement or fragmentation of the catheter that can be diagnosed initially only by clinical symptoms and later by a chest X-ray. We report a case of disconnection between the Port catheter and the reservoir resulting in catheter migration to the left pulmonary artery.
