IABP removal-manual balloon deflation

[RN-ing, BSN, MSN, NP]

Has anyone been taught by a rep or faculty not to manually deflate an IAB before pulling the sheath? Meaning, to let intra-aortic pressure deflate the balloon rather than manual deflation with a 60 cc syringe. I feel like I was taught that if manually deflated, the creases in the IAB can become sharp and potentially cause aortic dissection . I have found several removal policies online, but no rationale or case studies suggesting this has ever happened.

Any info would be helpful!

A long time ago it was recommended to aspirate with the 60cc syringe to ensure complete balloon deflation. Today, with the advances in technology and synthetic material it is said to no longer be necessary and to allow for the balloon to be deflected by the patients intra-aortic pressure. I know that the aspiration is now discouraged due to the potential for balloon rupture by to aggressive negative pressure and possibly air embolizing the patient. I hope this was helpful.
