BackgroundPerioperative management of antithrombotic therapy is a necessary preprocedural consideration for patients prescribed direct oral anticoagulants (DOACs), vitamin K antagonists, or antiplatelet medications. There is a lack of evidence-based guidelines to help inform decision-making in managing antiplatelet and anticoagulation medications in the perioperative period around brain tumor resection. The objective of this study was to provide an example of the heterogeneity in practice and raise awareness for the need to create standardized guidelines for managing these medications.MethodsA survey was sent to a list of over 800 international neurosurgeons who are members of the Neurosurgery Research Listserv. The survey comprised 70 questions assessing individual practices for managing thromboprophylaxis, antiplatelet medications, and anticoagulation in the perioperative period. The survey was sent via e-mail invitation between March 2021 and June 2021.ResultsA total of 72 surgeons responded to the survey. There was no difference in medication management preoperatively or postoperatively when comparing intra- and extra-axial tumor resections. Cessation of antiplatelet medications varied between 3 and 11 days while restart varied between 1 and 14 days. Preoperative management of vitamin K antagonists varied between indication for use (P < 0.001) while DOAC management did not. In our group of respondents, 90% started heparin products within 5 days of surgery, while the same fraction restarted DOAC within 14 days.ConclusionsRespondents demonstrated significant heterogeneity in their perioperative management of antiplatelet and anticoagulation medication in brain tumor resection. This may lead to an unacceptable level of heterogeneity in practice that has the potential to cause patient harm due to errors in medication management.Copyright © 2024 Elsevier Inc.
