Focal neurological manifestations following aberrant central venous catheter placement.

An infant developed focal tonic clonic movements of both lower limbs while receiving total parenteral nutrition through a left saphenous percutaneous central venous catheter. Radiographic studies using a contrast confirmed that the catheter tip was located in the ascending lumbar vein in close proximity to the epidural space. Withdrawal of the catheter abated all clinical symptoms. This case emphasizes the need to confirm central venous catheter placement and illustrates yet another risk associated with the infusion of parenteral alimentation.
