Incidence of Peri-Operative Complications Following Microsurgical reconstruction of 211 Septuagenarians and Octogenarians Babak J. Mehrara, MD; Michael A. Howard, MD; William Samson, MD; Peter G. Cordeiro, MD; Joseph J. Disa, MD; Robin Schoelle, PA There are an increasing number of elderly patients requiring free tissue transfer.(1) The risks of complex reconstructions in this patient population remain largely unknown.(2) Therefore, the purpose of this study was to review our experience with free tissue transfer in patients >70 years old. A retrospective review of all free tissue transfers performed over a ten year period at Memorial Sloan-Kettering Cancer Center was performed and all patients >70 years old were identified. Medical records and our prospectively maintained database were analyzed with respect to co-morbidities and postoperative complications. 211 patients aged >70 years (70-79yrs= 184; >80 yrs= 27) were identified during the study period. Of these, 197 patients had complete charts to review. Both groups were similar in their demographics. Flap survival was 100% in the 80+ and 97% in 70-79 groups. The overall complication rate was 59.3% in the 80+ group and 35.3% in the 7079 group (p=0.030). The medical complication rate was 40.7% in octogenarians and 11.8% in septuagenarians (p=0.0004). Overall surgical complications were similar in the two groups. Univariate analysis demonstrated that age was associated with medical complications. Using multivariate analysis, we found that alcohol use and coronary artery disease were independent predictors of overall, medical, and surgical complications. In summary, free tissue transfer may be performed in patients over age 70 with a high degree of technical success. The procedure however, carries a distinct risk of perioperative mortality and morbidity particularly in patients over the age of 80. Comorbidities significantly associated with complications include age, alcohol use, coronary disease, and hypertension. This study suggests that prolonged survival may be achieved in some patients; however, a selective approach is required.
