Table 2 Spleen organ injury scale. [75]

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, <5 cm in diameter
Capsular tear, 1 cm to 3 cm parenchymal depth that does not involve a trabecular vessel
III Haematoma
Laceration
Subcapsular, >50% surface area or expanding; ruptured subcapsular or parenchymal haematoma; intraparenchymal, haematoma >5 cm or expanding
>3 cm parenchymal depth or involving trabecular vessels
IV Laceration Laceration involving segmental or hilar vessels producing major devascularisation (>25% of spleen)
V Haematoma
Laceration
Completely shattered spleen
Hilar vessel injury devascularises spleen
