Retroperitoneal hemorrhage

Background

• bleeding into retroperitoneal space
• various etiologies: trauma, leaking/ruptured AAA, iatrogenic (colonoscopy, cardiac catheterization), spontaneous (coagulopathy), hemorrhagic pancreatitis
• difficult to diagnose given poor sensitivity of physical exam findings (Cullens, Grey-Turners)
• FAST and DPL do not evaluate retroperitoneal space
• can accumulate 4L blood before tamponade
• must have high clinical suspicion to make diagnosis

Differential Diagnosis

• Abdominal Aortic Aneurysm (AAA)

• Pancreatitis
• Iatrogenic
