Table 3 Liver organ injury scale. [75]

From: Angiography and embolisation for solid abdominal organ injury in adults - a current perspective

I Haematoma
Subcapsular, <10% surface area
Capsular tear, <1 cm parenchymal depth
II Haematoma
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
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
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
