نبذة مختصرة : Background: Concerns about increased risk of postoperative complications, primarily deep sternal wound infection (DSWI), prevent liberal use of bilateral internal thoracic artery (BITA) grafting inwomen. Consequently, outcomes after routine BITA grafting remain largely unexplored in female gender. Methods: Of 786 consecutivewomenwithmultivessel coronary diseasewho underwent isolated coronary bypass surgery at the authors' institution from 1999 throughout 2014, 477 (60.7%; mean age: 70 +/- 7.7 years) had skeletonized BITA grafts; their risk profiles, operative data, hospital mortality and postoperative complications were reviewed retrospectively. Risk factor analysis for hospital death, DSWI and poor late outcomes were performed by means of multivariable models. Results: There were 19 (4%) hospital deaths (mean EuroSCORE II: 5.2 +/- 6.1%); glomerular filtration rate b 50 ml/min was an independent risk factor (p = 0.035). Prolonged invasive ventilation (11.3%), multiple blood transfusion (12.1%) and DSWI (10.7%) were most frequent major postoperative complications. Predictors of DSWI were body mass index N35 kg/m2 (p = 0.0094), diabetes (p =0.005), non-elective surgical priority (p = 0.0087) and multiple blood transfusions (p = 0.016). The mean follow-up was 6.8 +/- 4.5 years. The nonparametric estimates of the 13-year freedom from cardiac and cerebrovascular deaths, major adverse cardiac and cerebrovascular events, and repeat myocardial revascularization were 76.1 [95% confidence interval (CI): 73.1-79.1], 59.5 (95% CI: 55.9-63.1) and 91.9% (95% CI: 90.1-93.7), respectively. Preoperative congestive heart failure (p = 0.04) and left main coronary artery disease (p = 0.0095) were predictors of major adverse cardiac and cerebrovascular events. Conclusions: BITA grafting could be performed routinely even in women. The increased rates of early postoperative complications do not prevent excellent late outcomes.
