Neurophysiological Intraoperative Monitoring During Aortic Surgery

Evaluation of the motor-evoked potentials/motor action potential amplitude ratio

时间窗: During thoracoabdominal aortic aneurysms surgery

The goal of this study is to evaluate the efficacy of different neurophysiological parameters in predicting patient outcome. In particular, our objective is to verify if a better identification of peripheral nerve ischemia during TAAA procedure can improve the sensibility of Intraoperative neurophysiological monitoring in detecting spinal cord ischemia and predicting clinical outcome. Exploratory univariate analyses will be performed using logistic regression to calculate odds ratios to evaluate neurophysiological parameters associated with poor outcome. Factors that will be found to be significant at p \< 0.05 will be then examined in subsequent multivariate analyses to determine significant independent predictors of poor outcome.
