Acquired hemophilia A (AHA) is a bleeding disorder due to the presence of neutralizing autoantibodies named inhibitors in patients with a previously normal hemostasis. Recent international recommendations suggest the use of bypassing agents or substitutive therapy as the first-line treatment, usually preferring the former. The adequate hemostatic therapy needs an accurate balance between bleeding and thrombotic risks. We report a clinical case of acquired hemophilia A successfully treated with recombinant porcine factor VIII (Susoctocog alfa) as the first-line treatment. Despite the patient having a high-risk thrombotic score and a history of recent myocardial infarction, our experience showed the absence of thrombotic complications related to the use of Susoctocog alfa and a complete restoration of hemostatic parameters. Limited literature is present on the use of recombinant porcine factor VIII as a first-line treatment, and our report supports its use, especially when the thrombotic risk is high.
