A 75-year-old man underwent an aortic valve replacement and CABG. The operation was complex and an intra-aortic balloon pump (IABP) in situ. Over the following hours, the balloon pump intermittently alarmed for gas leak. Reviews and troubleshooting from anaesthetic, surgical, and perfusion teams occurred, and the IABP was removed during a subsequent chest washout. Shortly after removal, the patient was found to have signs of acute right leg limb ischaemia. A CT scan confirmed gas embolism in the right iliac and distal vessels. He later required a right lower limb amputation.
