Intraoperative Blood Pressure and Hemorrhagic Complications after Brain Tumor Biopsies: An Observational Study Using a Propensity Score-matched Analysis.

ABSTRACT: Brain tumor biopsies are essential for pathological diagnosis. However, hemorrhagic complications after biopsies may occur, leading to suboptimal outcomes. This study evaluated the relationship between intraoperative blood pressure, especially anesthesia awakening, and hemorrhagic complications after brain tumor biopsies. We retrospectively collected data on consecutive patients with brain tumors (malignant lymphoma or glioma) who underwent a biopsy from 2011 to 2020. During the first half of the study period (until 2015), we managed patients with a mild blood pressure-lowering policy during awakening from general anesthesia, while in the latter half (after 2016), we aggressively lowered blood pressure below 140 mmHg. This blood pressure management was performed as a best practice. After p
