Abstract：Objective To investigate the application of positron emission tomography/computed tomography (PET/CT) in qualitative and localization diagnosis of deep occult infection of mediastinum after cardiac great vessel replacement.Methods The patients (n=6) with suspected deep occult infection of mediastinum after thoracic aorta replacement through median sternal incision were chosen from the Department of Cardio-Thoracic Surgery of Beijing Royal Integrative Medicine Hospital from Jan. 2013 to May 2017, and they were given 18F-fluorodexygl-gucose (FDG)-PET/CT examination. The infection scope and positions of artificial cardiac great vessels were decided according to PET/CT images. The operation methods and incision selection were guided by PET/CT images for debridement, drainage and muscle flap prothesis.Results Surgical exploration showed that all 6 patients had deep occult infection of mediastinum after cardiac great vessel replacement, and among them, 5 with infection spread round artificial vessels, 1 with infection involved vessel wall, and 2 complicated by sterna infection. PET/CT was accuracy in the diagnosis of deep occult infection of mediastinum after cardiac great vessel replacement in 6 patients.Conclusion PET/CT is accuracy in the qualitative and localization diagnosis of deep occult infection of mediastinum and infection round artificial vessels after cardiac great vessel replacement, which can be taken for guiding surgical debridement.
