Background: Coronary artery bypass grafting (CABG) operation is a surgical procedure commonly used in the treatment of patients with ischemic heart disease. In some cases, there is a need for re-exploration after CABG. This is a retrospective study conducted to determine the characteristics and risk factors of patients who underwent re-exploration because of bleeding after CABG operations in our center.
Materials and Method: In the present study, patients who underwent coronary artery bypass grafting (CABG) operation with open heart surgery and required re-exploration in Sanko University, Medicine Faculty Hospital Cardiovascular Surgery Clinic between December 2016 and May 2018 were evaluated retrospectively. The demographic data, laboratory findings, lengths of stay in the ICU, and total lengths of stay in the hospital of all patients were recorded. The patients were divided into two groups as patients who underwent and those who did not undergo re-exploration.
Results: A total of 200 patients, 131 (65.5%) males and 69 (34.5%) females, were included in this study. Of the patients, 13 (6.5%) had undergone the re-exploration operation because of bleeding after CABG. There was no statistically significant difference between the two groups in terms of age, gender, length of stay in the ICU and the total length of stay in the hospital. It was seen that 2 (15.4%) of the patients who underwent re-exploration were female and 11 (84.6%) were male. There was no significant difference between the patients in terms of preoperative period INR, APTT, BUN, creatinine, glucose, cholesterol levels, CBCT results and complete blood counts (p>0.05).
Conclusion: It was determined that the clinical features and laboratory parameters of patients who underwent CABG operation were inadequate for being used to predict the re-exploration to be implemented because of bleeding in these patients. It is thought that prospective studies with more detailed data and larger patient participation are needed for this subject.
