Outcomes in the management of sternal dehiscence by plastic surgery: a ten-year review in one university center.
OBJECTIVE
Infection rates following median sternotomy vary between 0.2% and 10%. These cases are associated with morbidity and mortality rates between 10% and 25% and 5% and 20%, respectively. The purpose of this study was to evaluate patient outcomes following plastic surgery correction of sternotomy dehiscence (SD).


METHODS
All patients operated on for an SD following coronary artery bypass graft surgery (CABG), between 1995 and 2005, with 1 or more flaps, were included.


RESULTS
Eighty cases were identified over a 10-year period. The mean age was 64 (+/-9.1) years. Two or more procedures were required in 17.5% of patients, and the mortality rate within 30 days was 12.5%. Significant variability was revealed between the cumulative mortality rates of plastic surgeons, from 0.0% to 50.0%. Multiple associations were identified for poor outcome, including chronic renal insufficiency and early mortality, and obesity with risk of reintervention.


CONCLUSIONS
Although patients who undergo surgical correction of a deep sternal infection usually tolerate their intervention well, the mortality within 30 days remains high. This study has identified several factors explaining morbidity and mortality in this patient population.
