[MSB-44] Evaluation of Sternum Closure Methods with Clinical Results in Open Heart Surgery.

OBJECTIVE

This study aimed to investigate the clinical results of sternum closure methods after open heart surgery with median sternotomy.

METHODS

This retrospective study screened 2,662 patients who underwent open heart surgery. Classical steel wire, Flexigrip + steel wire combination, sternal cable, sternal band, and Robicsek were used as sternum closure methods in patients. The causality relationships of sternal dehiscence, diabetes mellitus, chronic obstructive pulmonary disease, impaired kidney function, and demographic characteristics of the patients were investigated.

RESULTS

Ninety-six patients developed dehiscence, and 60% of them had diabetes, 25% had impaired renal function, and 21% had chronic obstructive pulmonary disease. The treatment success rate was 88% when using the Flexigrip + steel wire combination in patients undergoing sternal dehiscence repair, and the treatment success rate was 76% using a standard steel wire. The combination of Flexigrip + steel wire significantly reduced the risk of sternal dehiscence compared to the use of classical steel wire in sternal closure. Vacuum-assisted closure devices were beneficial in draining wounds and shortened the healing time.

CONCLUSION

Flexigrip + steel wire combination in sternal closure significantly reduced the risk of sternal dehiscence in patients with diabetes mellitus, chronic obstructive pulmonary disease, and impaired kidney function.
