Radiology of Intra-Aortic Balloon Pump Catheters

Radiographs play an important role in ascertaining appropriate placement of the intra-aortic balloon pump catheter. This imaging essay highlights correct and incorrect positioning of these catheters, with emphasis on the variability of radiopaque markers used with different catheter models and on axillary versus femoral catheter placement routes. Abbreviation IABP=intra-aortic balloon pump Knowledge and awareness of the different intra-aortic balloon pump (IABP) catheter radiopaque markers and routes of placement are necessary to identify correct or incorrect positioning of the IABP catheter on radiographs. Key Points n Intra-aortic balloon pump (IABP) catheters have different radiopaque markers that vary between model types and manufacturers. n IABP catheters are placed by two routes: The traditional femoral approach and the off-label axillary approach. n Close attention to IABP catheter markers is necessary to ensure appropriate positioning.
