CTICasesLooped Axillary Intra-Aortic Balloon Pump
Imaging findings
Radiograph shows an axillary-placed intra-aortic balloon pump (IABP) catheter with the radiopaque markers positioned close together in the ascending aorta, confirming that the catheter has looped on itself within the ascending aorta/arch.
Key takeaways
Axillary placement of IABPs allows for ambulation but increases the risk of catheter migration and mechanical failure. Radiologists must check the distance between the proximal and distal radiopaque markers; proximity or overlapping of these markers is a key sign of looping, requiring immediate repositioning.
