NIRS and BIS Monitoring During Cerebral Aneurysm Coiling

This prospective observational study aims to evaluate the effectiveness of Near-Infrared Spectroscopy (NIRS) and Bispectral Index (BIS) monitoring during endovascular coil embolization of cerebral aneurysms under general anesthesia. Changes in regional cerebral oxygen saturation (rSO₂) measured by NIRS will be assessed in relation to BIS values and hemodynamic parameters throughout the procedure. The frequency, duration, and severity of cerebral desaturation episodes detected by NIRS, as well as their association with anesthetic depth and hemodynamic fluctuations, will be analyzed. The study does not involve any additional intervention beyond routine clinical monitoring.
