Patients and methods:
Between January 2016 and December 2018, total 5990 OPCABG were performed in the department of the adult cardiac surgery at our center. One hundred and thirty two patients (2.2 %) were re-explored in the operation room (OR) and are included in our study. Patients explored for sternal wound infections, required graft revision (n=59) or required CPB during re-exploration were excluded from the study. The study was approved by our institutional ethics committee (UNMICRC/CVTS/2017/05) and written informed consent was waived off due to retrospective nature of the study. The medical records of these patients were retrospectively reviewed. The demographic data, preoperative data including preoperative use of antiplatelet, INR, creatinine etc, were noted. The intraoperative data of the main surgery as well as indication for re-exploration, duration of surgery, estimated blood loss and intraoperative findings during the re-exploration were also noted. Post-operative data including hospital and intensive unit stay, morbidity and 30- day mortality were also noted.
