AbstractMany patients with underlying cardiovascular disease require long-term anticoagulation. The perioperative or periprocedural management of patients who require temporary interruption of anticoagulant or antiplatelet medications is a common and often challenging clinical problem. It requires a fine balance between the risk of thromboembolic events during anticoagulant interruption and the risk of bleeding in the setting of antithrombotic therapy administered around the time of surgery. Interruption of anticoagulation is associated with an increased risk of thromboembolic events. Stratifying patients into thromboembolic risk groups may be helpful in directing anticoagulation management in the perioperative setting. Bridging anticoagulation, generally with low-molecular-weight heparin (LMWH), is often an integral part of perioperative thrombosis risk reduction. Perioperative anticoagulation management varies depending on the indication for anticoagulation and the anticoagulant or antiplatelet agent being used by the patient. In this article, we review some of the general principles involved with perioperative anticoagulation and discuss the perioperative management of patients taking vitamin K antagonists (VKAs), bridging regimens for anticoagulants and antiplatelet agents, and strategies for managing patients on the newer oral anticoagulants.
