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

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
