Study Notes

Liver Injury Overview

  • Liver trauma can manifest as subcapsular hematoma, intrahepatic hematoma, laceration, contusion, hepatic vascular disruption, and bile duct injury.

Grading of Liver Injury by AAST

  • Grading system developed by the American Association for the Surgery of Trauma (AAST).

Grade I

  • Involves a subcapsular hematoma covering less than 10% of the hepatic lobe.
  • Less than 1 cm deep capsule tear in the liver.

Grade II

  • A hematoma greater than 10% of the liver lobe without significant parenchymal injury.

Grade III

  • Includes larger lacerations or hematomas, typically over 3 cm deep, affecting multiple segments.

Grade IV

  • Involves major lacerations and vascular injuries, possibly including juxtahepatic venous injuries.

Grade V

  • Extensive liver damage or near-total vascular disruption, leading to significant hemorrhage.

Grade VI

  • Total devascularization of the liver, often resulting from severe trauma, such as in a motor vehicle accident.

Diagnostic Imaging

  • Computed tomography (CT) can reveal extensive, global liver injury, essential for assessing the severity of trauma.
