Premature newborn with new left femoral vein catheter that will not infuse

Venogram of perforation of femoral venous catheter out of the femoral vein
AXR AP (left) shows a left femoral venous catheter whose tip projects to the left of the L5 vertebral body, rather than projecting near the middle of the L5 vertebral body. AP venogram taken after injecting contrast through the femoral catheter (right) shows extravasation of contrast into the soft tissues surrounding the catheter tip.

The diagnosis was femoral venous catheter malfunction with perforation of the femoral venous catheter out of the femoral vein.
