Study Arms:
- open NIRS (Type: EXPERIMENTAL): continuous per operative cerebral oximetry monitoring (using INVOS™ cerebral oximeter) associated with hemodynamic optimisation algorithm (excluding norepinephrine) if cerebral oximetry decrease more than 15% under the preoperative baseline
- Blinded NIRS (Type: SHAM_COMPARATOR): Continuously monitored with cerebral oximeter but this latter is blinded to the medical team, the alarm switch off , and patients are managed with the standard care of the centre

Based on this trial design, predict the completion outcome and termination type (if applicable).
