Effects of Polyglyconate (Maxon) Suture Reinforced Sternum Closure Technique on Aseptic Sternal Dehiscence in High Risk Patients

Abstract

Introduction: Sternal dehiscence is a serious complication after cardiac surgery. The main objective of this study will be to determine the effects of polyglyconate suture (Maxon) reinforced sternum closure technique on prevention of aseptic sternal dehiscence in high-risk patients. Patients and Methods: This retrospective study (December 2011 to January 2013) comprised 136 consecutive patients undergoing standard median sternotomy for cardiac procedures. All of these patients have one or more risk factor of sternal dehiscence such as obesity, osteoporosis, chronic obstructive pulmonary disease and chronic active cigarette smoker. In all patients, in addition to steel wire during sternal closure polyglyconate sutures were placed, passing through the intercostal space. Results: No sternal dehiscence or mediastinit occurred these patients. Only 3 patients (2.2%) were observed superficial wound infection at lower part of sternum without sternum dehiscence and treated successfully by antibiotic therapy. Conclusion: This study shows that besides the classic steel wire, additional polyglyconate sutures placed intercostal spaces can be inhance sternum stability and prevent aseptic sternal dehiscence in high risk patients.
