Fig 1 Evidence of and bacteria colonizing sternal wound infections. (a) Graphical summary of the frequency with which various signs, symptoms, imaging of fluid collections, and biopsy indicative of osteomyelitis were reported in patients with mediastinitis. (b) Frequency of colonization of sternal wounds by various bacterium, and summarized graphically. (Bars = n of 22, and are not mutually exclusive; Coag Neg Staph. = coagulase negative Staphylococcus; CT = computed tomography; E. faecalis = Escherichia faecalis; S. aureus = Staphylococcus aureus.)

Fig 2 Changes in sternal wound size with the application of vacuum-assisted closure (VAC) therapy. (a–c) Photographs of a representative sternal wound after debridement, but (a) before VAC application, (b) after 2 weeks of VAC therapy, and (c) at completion of VAC therapy. (d) Graphical summary of mean changes in wound size in the 22 study patients. Bars represent mean ± SD with n = 22. *p < 0.05 compared with wound size before VAC application.

Fig 3 Management algorithm for deep sternal wound infections. The schematic details, in a stepwise fashion, the management of deep sternal wound infections at our institution. This process flows from initial presentation through assessment and establishing the presence of mediastinitis to treatment options, including standard therapies and vacuum-assisted closure (VAC) application. This process also highlights the patient population in whom we did not use VAC as well as the process by which we monitored improvements under VAC therapy and the resultant treatment options based upon those assessments.
