Non-invasive neuromonitoring tools such as transcranial doppler, optic nerve envelope diameter measurement and quantitative pupillometry are routinely used in acute brain injured patients as part of multimodal neuromonitoring with the aim, among others, of detecting episodes of intracranial hypertension, each method allowing the study of one of the different pathophysiological mechanisms of its impact.
However, at present there is no data in the literature on the value of these non-invasive neuromonitoring tools in the management of patients undergoing controlled intracranial surgery.
The study aims to help the early detection of postoperative neurological deterioration.

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Non-invasive neuromonitoring evaluation (transcranial doppler, optic nerve envelope diameter and quantitative pupillometry) | Other | 4 days Post-operation follow-up. Data will be gathered before the surgery and at regular times after the surgery until day 4 |
| Measure | Description | Time Frame |
|---|---|---|
| Evolution of non-invasive neuromonitoring measures (using transcranial doppler) | This emasure will be performed bilaterally at the level of the first part of the middle cerebral artery, the values collected will be:
| From 1 hour before the surgery until Day 4 post-surgery |
| Evolution of non-invasive neuromonitoring measures (optic nerve envelope diameter) | The diameter of the optic nerve envelope will be collected bilaterally using an ultrasound machine | From 1 hour before the surgery until Day 4 post-surgery |
| Evolution of non-invasive neuromonitoring measures (quantitative pupillometry) | The values collected will be : - Size, quantification of the amplitude of variation to light, latency and speed of constriction of the pupil, presence or absence of anisocoria (defined by a difference >1mm in size between the two pupils) | From 1 hour before the surgery until Day 4 post-surgery |
