Abstract

Background: Deep sternal wound infection (DSWI) or mediastinitis is a severe and life-threatening infection with high morbidity and mortality rates. Vacuum-assisted closure (VAC) provides good results and is very useful in wound closure. VAC therapy is a safe and affordable method for managing complex sternal and thoracic injuries. The use of VAC has been shown to increase parasternal blood flow by dilating arterioles, reducing bacterial load, and accelerating granulation tissue formation. It also helps with facilitating wound edge closure. Case and Operation Technique: A 6-month-old baby presented with an ulcer 2 cm deep in the thorax region. The wound had an exposed bone surrounded by slough and hyperemic edges. Bone destruction was seen to have reached the costochondral joint with a gross visible appearance of the pleura. Management of this patient included debridement, sternotomy, internal fixation of the sternum using the Robiscek technique, and application of the Water Shield Drainage (WSD) and VAC. The tobacco-sack technique was used to close the open wound. The Robiscek technique was used in this patient because of the bone destruction to the costochondral joints causing the sternum to become unstable. The VAC dressing was then connected to a suction with an intermittent negative pressure of 75mmHg. After a significant decrease in the wound surface area, a local rotational flap was used to close the wound. Conclusion: The use of modified VAC for deep sternal wound infection (DSWI) is effective, simple, and affordable with minimal complications.
