My bleeding patient on Warfarin has a history of recent thrombosis. Are PCCs still appropriate?
Yes, but it depends on the comparison of the risk (clot severity, location, timing) versus the benefit (bleed severity, treatability).
Consultation with a hematologist/thrombosis expert should be made.
- If the decision for reversal is made, PCCs should be administered given increased efficacy and no difference in thrombosis risk compared to plasma. Thrombosis risks in different meta-analyses for warfarin reversal in patients who received PCC or plasma and vitamin K are reported to be < 5%.
