Surgery - Bleed Risk

Bleeding risk for operations and procedures for warfarinised patients

Procedures at low risk of bleeding in warfarinised patients
  • Simple dental/periodontal work
  • Minor dermatological procedures


For such procedures, there is no need to stop or reverse anticoagulation, as the risk of bleeding is low, and if bleeding occurs it can be managed by local pressure.
Procedures at higher risk of bleeding in warfarinised patients

For non-minor procedures, anticoagulation will need to be reversed.

If there is a significant risk of thrombosis then bridging anticoagulation should be strongly considered.
