FIELD: medicine; neurosurgery.
SUBSTANCE: during endovascular surgery conduction intraoperative EEG monitoring is carried out. Doing so on the stage of provocation test with short-time action barbiturates, EEG bioelectricity changes presence or absence is directly monitored in real time. If sudden abnormal alterations in background EEG flowing bioelectric pattern are observed, the vessel is designated as functionally significant.
EFFECT: accuracy and objectivity increase in functional significance assessment of occluded vessel.
