retroperitoneal hemorrhage
Bleeding into the space behind the peritoneum, often difficult to detect and potentially life-threatening.
Full Definition
Retroperitoneal hemorrhage occurs when bleeding develops in the retroperitoneal space, the area behind the peritoneal lining of the abdominal cavity. This type of bleeding can result from trauma to major vessels, kidneys, or other retroperitoneal structures. Because this space can accommodate large volumes of blood before symptoms become apparent, retroperitoneal hemorrhage can be particularly dangerous and difficult to diagnose. The condition often requires advanced imaging for detection and may necessitate urgent surgical or endovascular intervention.
Usage
Usage note: Distinguish from 'retroperitoneal hematoma' - hemorrhage implies active bleeding.
