Perioperative management issues of direct oral anticoagulants.

The treatment repertoire of oral anticoagulation has changed dramatically over the past few years from one class of vitamin K1 antagonists to an increasing number of direct oral anticoagulants (DOACs). Clinicians are confronted with the problem of managing patients on novel agents in the critical setting before, during, and after surgery, where the risk of bleeding and thrombosis are increased simultaneously. Randomized clinical data are insufficient to date, but clinical exposure enlarges the body of experience. The following review considers perioperative management issues in various categories, including minor elective surgery, major elective surgery, and acute surgery. This review is a credo to personalized medicine where the patient's underlying thromboembolic risk status, the potential bleeding risk, or actual hemorrhagic manifestation determine the selection of multi-modal targeted management strategies.
