Acquired hemophilia a in a patient with lumbar disc herniation: a case report and review of the literature.

Abstract：

OBJECTIVE:To summarize the clinical manifestations and treatment of acquired hemophilia A in a patient with lumbar disc herniation. SUMMARY OF BACKGROUND DATA:Acquired hemophilia A is a rare but potentially life-threatening hemorrhagic disorder. It is caused by the development of autoantibodies directed against coagulation factor VIII (F VIII) in adults or elderly patients, who do not have a personal or family history of bleeding episodes. The mortality is high if the diagnosis was missed or delays, especially after a surgery. METHODS:A case was investigated retrospectively and the relevant literature was reviewed. RESULTS:A 59-year-old man with a 1-year history of lower back and leg pain was admitted to the hospital. He has no family medical history of hemophilia A and the routine laboratory examination did not find abnormality on blood coagulation function. He underwent decompression by laminectomy and discectomy. Seven hours after operation, it was found that the incision was oozing profusely and hemoglobin was reduced gradually, though platelet count was within the normal range. He was diagnosed with acquired factor VIII (FVIII) deficiency based on a prolonged activated partial-thromboplastin time (61.0 seconds), reduced FVIII activity (4.2%), and FVIII inhibitor (8 BU). After treatment with hemodynamic stabilization and immunosuppression therapies (including transfusion of packed red blood cells, fresh frozen plasma, and cryoprecipitate) and administration of human antihemophilic globulin, corticosteroid, and cyclophosphamide, bleeding was stopped gradually. The clinical and biologic condition of the patient improved, though neurological deficit was left. CONCLUSION:Surgical operation may be a factor contributing to acquired hemophilia A, which, to our knowledge, has not been reported in the literature. Diagnosis of acquired hemophilia requires clinical acumen and any patient who presents with bleeding and a prolonged activated partial-thromboplastin time should be considered. Initial hemodynamic stabilization followed by treatment with immunosuppressive therapy is straightforward and highly successful.
