Diagnosis and treatment of retroperitoneal hematoma in multiple trauma patients

From 1984 to 1991 20 multiple trauma patients with pelvic fractures and retroperitoneal bleeding from pelvic vessels underwent angiographic localization and embolization of massively bleeding arterial vessels. Nine patients survived (multiple trauma index grade III, Hanover polytrauma index), three patients with very severe injuries died immediately (multiple trauma index grade IV). After successful control of bleeding by embolization, three other patients died from severe brain injuries and five patients from septic multiorgan failure. The interval to definite localization and treatment of the bleeding source was three times shorter in the group of survivors, and the amount of transfusions needed was less by a factor of three. This underlines the importance of early angiography in multiple trauma patients with pelvic fractures and persisting hemorrhage. Embolization has proven to be effective in the treatment of such injuries.
