Abstract:
Objective:To evaluate the qualitative and localization diagnostic value of PET/CT in chronic sternal median incision infection after heart surgery and the guiding function of PET/CT image in debridement .Methods:Twenty‐one patients with chronic sternal median incision infection admitted to our hospital from February 2015 to December 2015 underwent PET/CT examinations within one week prior to surgery were selected .Detection of extent of sternal wound infection and localization diagnoses of costal chondritis were conducted by using PET/CT and CT ,and the results were compared with the diagnosis results during surgery .The qualitative and localization diagnostic value of PET/CT in chronic sternal median incision infection were evaluated .Debridement was guided by the PET/CT images .Patients were followed up for 6‐16 months after operation ,and the debridement and reconstructive surgery effect on chronic sternal median incision infection was evaluated . Results:There were 20 cases of sternal osteomyelitis ,18 cases of mediastinitis ,and 9 cases of costal chondritis .Accuracies of PET/CT in above diagnoses were all 100% .Sensitivity ,specificity ,positive predictive value ,negative predictive value ,and accuracy of PET/CT in localizing involved costal cartilages were 85 .71% ,99 .74% ,96 .00% ,98 .99% ,and 98 .81% , respectively .Sensitivity , negative predictive value , and accuracy of PET/CT in localizing involved costal cartilages were significantlyhigherthanthoseofCT(Pvalueswere0.002,0.008,and0.01).Curerateofpatientswithcostalchondritisafter first debridement operation was 85 .7% .Conclusions:PET/CT is of high accuracy in qualitative diagnosis and localization compared with CT in chronic sternal median incision infection after heart surgery , which is promising in guidance of debridement operation .
