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.
