Abstract
A 39-year-old woman who was taking contraceptive pills was admitted with
right leg deep venous thrombosis (DVT). She was started on apixaban
tablets, and after 8 days, she developed proximal progression of DVT and
pulmonary embolism. Her past medical history later showed a history of
sleeve gastrectomy. The patient responded to a vitamin K antagonist
after heparin. The failure of the antithrombotic drug shed light on the
efficacy and pharmacodynamic changes of DOACs after bariatric surgery in
the absence of commercially available blood monitoring tests.
Key words Apixaban, Bariatric Surgery, thromboembolism
