RESUMO
INTRODUCTION: Free tissue transfers are more often performed in the elderly with the increase in geriatric patient population. The aim of this study was to investigate the effect of advanced age in reconstructive microsurgery procedures and analyze the association of other variables with complications and surgical success. PATIENTS AND METHOD: A retrospective review of 70 consecutive free tissue transfers between January 2012 and June 2013 was performed. Patients were divided into 2 groups: those younger than 60 years and those aged 60 years or older. Besides demographics, the American Society of Anesthesiologists (ASA) risk score, comorbid conditions, and anatomic locations for surgery (head and neck, extremities, trunk), operative time, need for reoperation, intensive care unit (ICU) admission and blood transfusion, length of hospital stay, medical and surgical complications, as well as partial and total flap loss were noted and analyzed. RESULTS: A total of 71.4% of the patients were younger than 60 years (n = 50; average, 37.4 y), and 28.6% of the patients were 60 years or older (n = 20; average, 67.5 y). None of the other collected data showed significant difference between the groups. Although age was not associated with ICU admission, the location of the reconstruction site and the operative time were found to have a significant correlation with ICU referral. In this series, the operative time correlated with medical complications but not with surgical complications. Higher ASA scores did have a negative effect on the incidence of medical complications (P = 0.028). CONCLUSIONS: This retrospective review demonstrates that age alone is not an independent variable for increased risk in microvascular reconstruction. However, operative time, ASA risk score, and location of the reconstruction site are more associated with the overall success of free tissue transfers.
