The intractable intra-abdominal hemorrhage with unknown etiology in a patient with severe hemophilia A

Severe hemophilia patients are more likely to be complicated by intra-articular hemorrhage, subcutaneous hemorrhage, and intra-mascular hemorrhage. Spontaneous intra-abdominal hemorrhage is a rare fatal disease, which is an arterial bleeding of uncertain causes from vessel feeding arteries. In case the spontaneous intra-abdominal hemorrhage is complicated to severe hemophilia patients, the mortality rate increases considerably. We experienced a patient with severe hemophilia A, who made a full recovery from spontaneous intra-abdominal hemorrhagic shock by replacement therapy of coagulation factor VII, a noninvasive procedure.
