Reconstruction for poststernotomy sternal osteomyelitis and mediastinitis follow median sternotomy

Objective:To evaluate the clinical effect of debridement and thoracic reconstruction as surgical treatment for sternal osteomyelitis and mediastinitis after sternotomy.Methods:The surgical procedures,clinical results and follow-up of 58 cases of poststernotomy sternal osteomyelitis and mediastinitis those underwent debridement and thoracic reconstruction with pectoralis major muscle flaps from January 2008 to April 2011 were analyzed retrospectively.Results:All 58 muscle flaps remained alive.52 patients recovered and discharged in 2 weeks,4 patients were discharged in 4 weeks for infection.2 patients presented subcutaneous infection at 1 week post discharge,but recovered following local debridement and medication.No patients showed subcutaneous infection recurrence during the follow-up period.Conclusion:Debridement and thoracic reconstruction with pectoralis major muscle flap are safe and effective in the treatment of poststernotomy sternal osteomyelitis and mediastinitis.
