    BackgroundPhaeochromocytoma and paraganglioma resection carries a high perioperative risk. The aim of this study was to determine the risk factors for and frequency of perioperative morbidity and mortality during resection of these tumours.MethodsComputerized surgical, medical, and histopathology records, as well as anaesthesia cards for 145 patients undergoing surgery for phaeochromocytoma resection between 1995 and 2009 were analysed retrospectively. Preoperative notes, adverse intraoperative events, and postoperative complications occurring in the 30 days following surgery were recorded. Preoperative phenoxybensamine and propranolol dose, age, sex, ASA score, catecholamine urinary level and profile, tumour weight, duration of surgery, and malignancy and presence of bilateral tumours were investigated to determine their contribution to major intraoperative haemodynamic events. Univariate comparisons were carried out using the student t-test. The Mann-Whitney test was also used to allow for deviation from normality. Logistic regression with backward removal of insignificant variables was used for multivariate analysis. Spearman test was used for correlation analysis.ResultsThe only statistically significant factor that increased the probability of intraoperative haemodynamic variability was the duration of surgery (p = 0.025). The most common intraoperative event was transient hypertension, occurring in 59 (40.7%) patients. Sustained hypertension was registered in only 10 (6.9%) patients. No mortality, myocardial infarction, or cerebrovascular incidents were recorded.ConclusionsWe found that the severity of perioperative haemodynamic changes significantly correlated with the duration of surgery. Our patients had low perioperative morbidity and no mortality.
