retroperitoneal hematoma
Bleeding into the retroperitoneal space, often from pelvic fractures or major vessel injury, requiring careful hemodynamic monitoring.
Full Definition
Retroperitoneal hematoma is a collection of blood in the retroperitoneal space, most commonly resulting from pelvic fractures, renal trauma, or injury to major retroperitoneal vessels. These hematomas can be massive and life-threatening due to the large potential space and difficulty in achieving hemostasis. Clinical presentation may be subtle initially, with flank pain, abdominal distension, or hemodynamic instability. Management depends on the source and severity, ranging from conservative monitoring to emergency surgical or endovascular intervention. CT imaging is essential for diagnosis and monitoring.
Usage
