Case Notes

Bentall procedure is a surgical reconstruction technique involving the replacement of the aortic valve, aortic root, and ascending aorta, with reimplantation of the coronary arteries, utilized in the treatment of various aortic pathologies. Graft infection following Bentall procedure occurs in 1% to 5% of cases and is asscociated with a mortality rate of 7% to 21% . FDG PET/CT can distinguish between typical postoperative alterations and infection, potentially serving as a diagnostic tool for graft infection in patients undergoing Bentall procedure.
