Accelerated Apixaban Removal by Using the ADVanced Organ Support (ADVOS) Albumin Hemodialysis System-A Case Report.

BACKGROUND

In patients on direct oral anticoagulants (DOAC), emergency surgery is characterized by the occurrence of a massively increased tendency to bleed. Currently, there is no approved antidote for postoperative patients, making specific therapy challenging in these situations.

CASE DESCRIPTION: Emergency surgery was required for a 72-year-old male patient who was in cardiogenic shock due to severe aortic regurgitation resulting from acute prosthetic valve endocarditis. Due to atrial fibrillation, the patient was on apixaban, a factor Xa (FXa) inhibitor anticoagulant, until surgery. We used the ADVanced Organ Support (ADVOS) albumin hemodialysis system postoperatively to treat persisting shock with multi-organ failure, acidosis, and DOAC removal. Serial drug-level measurements revealed strongly accelerated apixaban clearance. In line with this, we observed only moderate drainage losses.

CONCLUSION

ADVOS accelerates the removal of apixaban and is a promising therapy for preventing bleeding complications in patients receiving DOAC therapy after emergency surgery.
