title: [Detection of a cerebral ischaemia episode during surgery by monitoring the brain tissue oxygen pressure].
abstract: The detection and treatment of cerebral ischaemia and tissue hypoxia for the prevention of secondary injury are the basic objectives during anaesthesia for neurosurgical procedures. The monitoring of the tissue oxygen pressure is direct and can enable potentially harmful situations to be detected in real time. Although it was initially used in neurocritical patients, its use has extended to surgical patients. We present the case of a patient subjected to surgical resection of a dural arteriovenous fistula in which the brain tissue oxygen pressure around the area of the lesion was monitored. The finding of an episode of cerebral tissue hypoxia during closure of the craniotomy determined the treatment of the patient. We highlight the possible use of this neuromonitoring for the rapid detection of regional cerebral hypoxia events in the peri-operative period of vascular neurosurgery, procedures that have a significant risk of, mainly ischaemic, hypoxia episodes.
