CTICasesIatrogenic PICC Line Migration during Power Injection
Imaging findings
CT angiography shows a PICC line catheter tip migrated retrograde into the internal jugular vein. A scout radiograph obtained immediately prior, and a follow-up CT shortly after, show the catheter tip in the correct position within the SVC.
Key takeaways
High-pressure contrast injection (power injection) through a PICC line can cause transient, retrograde migration of the catheter tip (acting like a water rocket) up into the jugular vein. The tip typically returns spontaneously to the SVC once flow stops, making this a transient artifact.
