I | Haematoma Laceration | Subcapsular, <10% surface area Capsular tear, <1 cm parenchymal depth |
---|---|---|
II | Haematoma Laceration | Subcapsular, 10% to 50% surface area; intraparenchymal, <10 cm in diameter Capsular tear, 1 cm to 3 cm parenchymal depth, <10 cm in length |
III | Haematoma Laceration | Subcapsular, >50% surface area of ruptured subcapsular or parenchymal haematoma; intraparenchymal, haematoma >10 cm or expanding >3 cm parenchymal depth |
IV | Laceration | Parenchymal disruption involving 25% to 75% hepatic lobe or 1 to 3 Couinaud's segments |
V | Laceration Vascular | Parenchymal disruption involving >75% of hepatic lobe or >3 Couinaud's segments within a single lobe Juxtahepatic venous injuries, ie retrohepatic vena cava/central major hepatic veins |
VI | Vascular | Hepatic avulsion |
