How should chronic anticoagulation be handled before surgery?

• A. Stop anticoagulation permanently.
• B. Do not alter anticoagulation regimen.
• C. Balance bleeding risk with thrombosis risk; often hold anticoagulants with bridging if indicated; coordinate with prescribing clinician.
• D. Increase anticoagulant dose before surgery.

Answer: (C)

Managing chronic anticoagulation before surgery requires weighing bleeding risk against thrombosis risk and planning accordingly. The best approach is to balance these risks by stopping the anticoagulant for a period to reduce surgical bleeding, and, in patients with high thrombotic risk, using bridging with a short-acting anticoagulant (like heparin) when indicated. This plan should be coordinated with the prescribing clinician, the surgical team, and anesthesia, because the timing depends on the specific drug (warfarin, DOACs, LMWH), the patient’s kidney function, and the procedure’s bleeding risk. By individualizing the plan, you protect against perioperative bleeding while minimizing the chance of a clot forming. Stopping permanently, not altering the regimen, or increasing the dose before surgery do not appropriately balance these competing risks.
