For all warfarin indications, perioperative bridging is not indicated in patients at low risk of thromboembolism.1 For patients with a high risk of thromboembolism, bridging with a therapeutic dose of unfractionated heparin or LMWH is indicated.1 The ACCP guidelines are less clear about how patients with a moderate risk of thromboembolism should be treated.1 Clinicians need to balance the individual's risk of thromboembolism, based on the medical history and surgical procedure, and risk of bleeding when determining what is optimal in persons in this moderate-risk category.
