Postpartum-Acquired Hemophilia A Presenting as Hemoperitoneum: A Case Report.

Acquired hemophilia A (AHA) is a bleeding diathesis caused by the production of autoantibodies to factor VIII (FVIII). It manifests as an isolated deranged activated partial thromboplastin time (aPTT) indicating a defect in the intrinsic coagulation pathway. Herein, we report a case of a 26-year-old woman who presented with hemoperitoneum in the postpartum period following a lower segment Caesarean section (LSCS). AHA carries significant mortality if it remains undiagnosed, and early recognition and measures to eradicate the acquired inhibitors are the mainstays of its management.
