Objective: To demonstrate the experience with the reconstruction of the chest wall utilizing metal brace to reduce the tension in the suture lines of myocutaneous flap in cases of mediastinitis.
Methods: From July 2001 to February 2006, 1389 heart surgeries were performed in our institution of which eight (0.6%) developed mediastinitis. Seven were male and the mean age was 56.7 years. The risk factors for infection were diabetes and obesity in seven and malnutrition in one case. Seven patients had been undergone CABG and one repair of a congenital heart disease. The chest wall reconstruction consisted of percutaneous insertion of Kirshner wires parallel to the edges of the wound for anchoring of sutures to the muscular plane in order to allow the reduction of tension in the free edges of the wound and subsequent closure of the subcutaneous tissue and skin.
Results: There was one death in the immediate postoperative due to arrhythmia and one late death secondary to sepsis. The remaining patients presented satisfactory postoperative course with good healing of the wound after the removal of the metal braces on the 21st postoperative day and in the follow-up of 6 to 54 months.
Conclusion: The reconstruction of the chest wall utilizing temporary metal braces showed to be a safe and effective procedure with good aesthetic and functional outcomes in this group of patients.
