Preschooler with a central venous catheter that will no longer draw back

CXR of central venous catheter fracture
CXR AP when the catheter was placed one year ago (left) shows the tip of the catheter at the cavoatrial junction in correct position. CXR AP today (right) shows the catheter is now fractured and discontinuous and has embolized into the right atrium.

The diagnosis was central venous catheter fracture.
