Heparin Insensitivity and Thrombotic Risk Associated With Sequential Uses of Prothrombin Complex Concentrate and Andexanet Alfa for Apixaban Reversal During Acute Type A Aortic Dissection Repair: A Case Report

A A Pract. 2022 Nov 4;16(11):e01636. doi: 10.1213/XAA.0000000000001636. eCollection 2022 Nov 1.

Abstract

The management of patients on direct oral anticoagulants (DOACs) who require emergent cardiac surgery is slowly evolving. The introduction of andexanet alfa, a novel antidote for apixaban and rivaroxaban, added a specific reversal agent to our armamentarium, but its safety and efficacy are still being investigated. We report 2 patients on DOAC treatment who required emergency cardiac surgery. Both received perioperative andexanet alfa together with prothrombin complex concentrate (PCC) at some time during 6 hours before operative management. Heparin resistance was noted in each instance, and pump thrombosis developed in 1 case.
