Abstract

<p>Bypass therapy using recombinant activated factor Ⅶ (rFⅦa) or activated prothrombin complex concentrate (APCC) is effective for hemostatic treatment in acquired hemophilia A. We report the case of a 78-year-old man who presented with severe oropharyngolaryngeal hematoma after tooth extraction despite using rFⅦa to manage acquired hemophilia A.</p><p>　He was referred to our department because of tenderness of the tongue caused by a metal crown of the left mandibular first molar. About 3 months before our first medical examination, the patient was given a diagnosis of acquired hemophilia A, for which he had subsequently received corticosteroids and had undergone bypass therapy using APCC in the Department of Hematology of our hospital. Panoramic radiography revealed chronic apical periodontitis of the same tooth. We consulted a hematologist. For hemostatic management, rFⅦa preparations were transfused before and after the extraction procedure. However, submucosal hematoma and edema developed in the oral floor the next morning and advanced to the root of the tongue and epiglottis on the following 2 days. We urgently performed intratracheal intubation. After that, rFⅦa preparations were transfused every 3 hours, and the patient was extubated 12 days after tooth extraction.</p>
