• Penetrating• Blunt• Non• Non

IVC Trauma due to penetrating injury
•High mortality (70%)•Higher if other associated vascular injuries•Recognised as a severe marker of injury•Consider other involved structures

IVC TRAUMA - Imaging
• Range of injuries • Severity of injury• Difficulty of imaging - rate of blood loss and
poor identification• Rare finding. They often die before reaching
CT

IVC TRAUMA - IMAGING SIGNS
• Index of suspicion. If you don't look for it, you won't find it.
• Active bleeding on CT
• Retro peritoneal haematoma
• Adjacent organ injury or other injuries
• Flat IVC
• Direct/indirect. Two lists

IVC TRAUMA - SUMMARY
• Marker of v severe injury• Rarely reaches imaging• Awareness of potential allows recognition • Underestimation of depth of penetration in
penetrating injury• Underestimation of haemorrhage in
penetrating injury
