Abstrakt:	Background: Sternal dehiscence is a serious postoperative complication of cardiac surgery observed in 0.2-5% of procedures performed by median sternotomy. Objectives: Assessment of factors, including the method of sternum closure, which may affect the incidence of this complication. Material and Methods: A total of 5,152 consecutive patients undergoing surgery with median sternotomy access in the Cardiac Surgery Department of the Pomeranian Medical University between 2010 and 2014 were included in the study. The analysis centered on cases of sternal dehiscence, which occurred in 45 patients (0.9%). Results: Factors such as age (p < 0.05), body mass (p < 0.005) and coronary artery bypass surgery (CABG) (p < 0.005) were found to be significant risk factors. Diabetes and chronic obstructive pulmonary disease (COPD) also had an impact on an increased risk of sternal dehiscence (p < 0.006 and p < 0.015). However, the differences were only significant in the whole study group. Apart from CABG, the type of operation did not affect the incidence of dehiscence. Logistic regression analysis found independent risk factors for the development of sternal dehiscence: body mass index (BMI) (odds ratio (OR): 2.1; p < 0.019), diabetes (OR: 2.4; p < 0.004), COPD (OR: 2.7; p < 0.016), and redo procedure (OR: 3.0; p < 0.014). There were no significant differences in postoperative mortality between these groups - 6.7% in the group with sternal dehiscence and 3.9% in the group without dehiscence. Conclusions: Introducing a more durable sternum stabilization method with 8+ loops helped to improve conditions for bone union and reduced the risk of dehiscence. Therefore, we suggest that centers which still use 6-loop sternal closure should consider shifting to a stronger technique.
