Objective: To assess the possibilities of omentoplasty for prevention of complications after redo sternum osteosynthesis for traumatic rupture., Material and Methods: The study included 53 patients with recurrent sternal diastasis. Greater omentum was additionally implanted in 19 (35.8%) cases to improve healing and reduce the risk of infectious complications. In 34 patients, redo osteosynthesis was carried out using a metal wire and deployment of irrigation-aspiration system. In 19 patients, omentoplasty was additionally used to close the wound., Results: Omentoplasty was characterized by less duration of lavage (7.4±1.5 vs. 4.2±3.3 days, p <0.0001) and no cases of arrosive bleeding ( p =0.04)., Conclusion: Omentoplasty reduces duration of treatment and risk of arrosive bleeding.

Objective: To evaluate bacterial flora in patients with deep sternal wound infection and the effect of negative pressure wound therapy on eradication of the pathogen., Material and Methods: There were 102 patients with deep wound infection after cardiac surgery. Mean age was 66.9±9.9 years. Diabetes mellitus was detected in 21 (20.5%) cases, chronic obstructive pulmonary disease - in 15 (14.7%). Wound debridement via daily dressings was performed in 64 patients; vacuum-assisted dressings were applied in 38 patients. Bacteriological analysis of discharge was carried out every week., Results. Mixed infection was observed in 38 (37.3%) patients. S.aureus was the most common pathogen ( n =51, 50%), Gram negative bacteria were found in 36 (35.3%) patients. Negative pressure wound therapy ensured eradication of S.aureus within 3 weeks while dressings were associated with only 40% decrease of the incidence of positive analyses ( p <0.05). Effectiveness of the method was not obtained for Gram negative bacteria., Conclusion: Negative pressure wound therapy accelerates eradication of Gram positive pathogens but does not affect eradication of Gram negative microbes.
