Relationship between intraoperative hypertension and postoperative ischemic stroke in neurosurgery—a retrospective cohort study

Intraoperative hypertension is a significant predictor of postoperative ischemic stroke in neurosurgical patients, with peak value, the duration, and AUC all demonstrating independent predictive values. These findings underscore the critical need for vigilant intraoperative blood pressure monitoring and management to mitigate stroke risk in neurosurgical patients.
