• Blunt trauma to pancreas is usually caused by compression against the vertebral column; the best and most common example is seat belt compression injuries. Blunt trauma to pancreas is Usually associated with upper abdominal visceral injury.
• Graded from minor contusion and capsular haematoma (grade I) to severe devascularising crush injury (grade IV).
• Pancreatic trauma is usually damage occurs at most vulnerable segment of pancreas: the junction of the body and tail.
•Laceration–area of intrapancreatic low attenuation, often difficult to see.
•Direct evidence of haemorrhage – fluid around superior mesenteric artery and pancreas.
•Indirect evidence – thickening of anterior pararenal fascia.
- Often requires delayed scans to exclude/monitor complications of pancreatitis and devascularised pancreas.
Complications of Blunt trauma to pancreas

- peripancreatic fat stranding
- diffuse or focal pancreatic enlargement
- irregular pancreatic contour.
• Splenic vessel fistula or arterial pseudoaneurysm.
• Pancreatic abscess.
• Pancreatic pseudocyst.
