Catheter tip migration following power injection of contrast medium through a pressure-resistant central venous port: A case report

Pressure-resistant central venous ports allow power injection of contrast medium for contrast-enhanced computed tomography scans. While such ports provide significant benefits for patients requiring long-term venous access, concerns remain regarding catheter-related complications, particularly catheter tip displacement. We present a case of catheter tip migration from the superior vena cava to the right brachiocephalic vein following the power injection of a contrast medium through a pressure-resistant central venous port during a contrast-enhanced computed tomography examination. We propose practical strategies for the safe use of pressure-resistant central venous ports for power injection of contrast medium based on our experience with the present case, highlighting the potential risks of catheter tip displacement and possible counter measures.
