Idiopathic spontaneous intraperitoneal hemorrhage: a clinical update on abdominal apoplexy in the year 2001.

Idiopathic spontaneous intraperitoneal hemorrhage is a rare and often fatal condition that has been historically referred to as abdominal apoplexy. The presentation varies widely, and preoperative diagnosis is seldom obtained. Immediate surgical exploration remains the treatment of choice. At the time of exploration a through examination of the visceral arteries and solid organs should be done, as these are common sites for intra-abdominal bleeding. Often the site of hemorrhage cannot be localized at time of surgery despite thorough exploration. Today a postoperative diagnosis can often be confirmed and treated with interventional radiology. In rare cases the site of bleeding remains unknown despite intraoperative exploration and radiographic studies.
