Preschooler with a dual port central catheter whose white port is not working well

Cardiovascular
Line study showing dual port central venous catheter
Image from a line study while injecting the white port of the catheter (left lower) shows the lumen of the white port is one-third the diameter seen while injecting the red port of the catheter (right lower). No fibrin sheath or clot was seen.

The diagnosis was a normal appearance of a dual port central catheter.
