retroperitoneal hematoma
A collection of blood in the retroperitoneal space, often following blunt abdominal trauma or vascular injury.
Full Definition
Retroperitoneal hematoma refers to bleeding into the retroperitoneal space, the area behind the peritoneum that contains the kidneys, pancreas, duodenum, and major blood vessels. This condition commonly occurs following blunt abdominal trauma, particularly involving the pelvis or lumbar spine, or as a complication of vascular procedures. The retroperitoneal space can accommodate large volumes of blood before symptoms become apparent, making early detection challenging. Classification systems help guide management, with some hematomas requiring immediate surgical intervention while others can be managed conservatively with close monitoring.
Usage
Usage note: Often abbreviated as 'RP hematoma' in clinical documentation.
