IntroductionDirect oral anticoagulants (DOACs) have gained momentum in recent years in patients requiring anticoagulation for the prevention and management of venous thromboembolism and thromboembolic events caused by atrial fibrillation. The use of these agents involves potential bleeding complications, particularly during invasive procedures. With increasing use of DOACs, adequate knowledge regarding the perioperative management of patients on DOACs has become indispensable.Areas CoveredThis review covers the indications, mechanism of action, and pharmacokinetics of DOACs and their management in different perioperative settings based on various current guidelines and practices. The role of bridging therapy with heparin and the recently developed reversal agents are also discussed.Expert OpinionThe perioperative management of DOACs is influenced by drug pharmacokinetics, potential comorbidities of the patient and perioperative thrombotic and bleeding risk. In low bleeding risk and minor procedures, continuing DOACs seems to be safe. Interrupting DOACs in high-risk procedures might be necessary and should be based on the elimination half-life of the drug and renal function of the patient. Further research is needed to better clarify the role of recently developed reversal agents in the perioperative setting and to identify specific laboratory tests to guide the perioperative management of DOACs.
