Radiology casebook. Unusual misplacement sites for central venous catheters: three case reports.

Umbilical venous catheters and percutaneously placed central venous lines play an integral role in the management of critically ill newborn infants. Health care providers involved with the placement of these catheters must be familiar with, and able to diagnose, subtle sites for catheter misplacements. Three cases are presented illustrating potential sites of misplacement. The indications, placement, and associated complications of central venous lines reported in the literature are briefly reviewed.
