In this study, intraoperative blood viscosity and related hematologic parameters will be measured, and their relationships with cerebral oxygenation and postoperative complications will be analyzed.\n\nThe study will enroll adult patients undergoing elective intracranial surgery at a single tertiary center. The findings of this study may improve understanding of perioperative hemodynamic and hemorheological factors and help identify potential risk markers for adverse postoperative outcomes.",[26,27],"Postoperative Complications","Intracranial Surgery",[29,30,31,32,33,34],"blood viscosity","intracranial craniotomy","neurosurgery","cerebral oxygenation","postoperative complications","hemodynamics","NOT_YET_RECRUITING","2026-04-07",{"date":38,"type":39},"2026-04-15","ACTUAL",{"date":41,"type":21},"2026-05-01",{"date":43,"type":21},"2030-03-31",{"name":45,"class":46},"Asan Medical Center","OTHER"]
