School ager with a central venous catheter that infuses but does not draw back

CXR of central venous catheter tip occlusion against a vessel wall — CXR AP from one month ago (above) shows the tip of the central venous catheter to be at the junction of the superior vena cava and the right atrium. CXR AP today (below) shows the tip of the central venous catheter to have migrated back into the right subclavian vein and the tip of the catheter is occluded against the wall of the subclavian vein.

The diagnosis was central venous catheter malfunction after the catheter tip migrated from the superior vena cava to the right subclavian vein and the tip became occluded against the wall of the right subclavian vein.
