What this Trial Is About
The goal of this clinical trial is to evaluate whether non-invasive continuous blood pressure monitoring (NVBP) using the ClearSight system can safely serve as an alternative to radial arterial catheterization for invasive arterial blood pressure monitoring (IABP) in patients undergoing coil embolization for unruptured intracranial aneurysms. The main questions it aims to answer are: * Does NVBP monitoring detect intraoperative hypotension and hypertension events with similar reliability compared to IABP? * Does NVBP monitoring reduce the need for invasive arterial catheterization without compromising patient safety or clinical outcomes? Researchers will compare patients assigned to NVBP monitoring with those receiving conventional IABP monitoring. Participants will: * Be randomly assigned to NVBP monitoring or standard IABP monitoring during coil embolization. * Receive continuous monitoring of cerebral oxygenation with near-infrared spectroscopy (rSO₂). * Undergo standard anesthesia induction, maintenance, and postoperative intensive care protocols. * Have their intraoperative hemodynamic events, vasopressor use, and postoperative outcomes recorded up to 30 days after the procedure.
