This study investigated the association of age and postoperative complications in two different age groups undergoing thoracotomy and pulmonary resection. We retrospectively reviewed the medical records of all patients (n=150) older than 60 years who underwent pulmonary operations between January 2000 and December 2001. Group A consisted of 91 patients at the age of 60-69 years. In group B, there were 59 patients older than 70 years. We recorded preoperative assessment, clinical parameters, pre- and postoperative complications. The incidence of postoperative complications were compared between the two age groups using univariate and multivariate analysis. The incidence of postoperative complications in group A was 30% compared to 35.6% in group B. The most frequent complications were: cardiac arrhythmias 9.9% in group A vs. 15.2% in group B, and prolonged air leak 8.8% in group A vs. 8.5% in group B. Thirty days mortality was 0 vs. 1.2%. We concluded that there was no significantly higher incidence of postoperative complications in these two age groups.
