AbstractPostoperative symptomatic spinal epidural hematoma (PSSEH) is a serious complication of spinal surgery that is associated with significant morbidity. Studies suggest that hypertension is a risk factor for the development of PSSEH. The aim of this review was to evaluate the literature reporting associations between hypertension and PSSEH. A comprehensive literature search was conducted using the MEDLINE/PubMed, Embase, and Cochrane Library databases to identify studies that investigated PSSEH and reported data on preoperative hypertension status and/or perioperative blood pressure (BP). Eighteen studies were identified for inclusion in the review. Observational data suggested that uncontrolled/untreated preoperative hypertension, extubation-related increases in systolic BP, and elevated postoperative systolic BP were associated with an increased risk of PSSEH. The overall quality of evidence was low because of the retrospective nature of the studies, heterogeneity, and lack of precision in reporting. Despite the limitations of the current evidence, our findings could be important in establishing preoperative BP targets for elective spine surgery and inform perioperative clinical decision-making, while allowing consideration of risk factors for PSSEH. Well-controlled studies are required to investigate further the relationship between BP and PSSEH.Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
