Subcapsular haematoma <10% of surface area Parenchymal laceration <1 cm depth Capsular tear
Subcapsular haematoma 10–50% of surface area; Intraparenchymal haematoma <5 cm Parenchymal laceration 1–3 cm
Subcapsular haematoma >50% surface area; ruptured subcapsular or intraparenchymal haematoma ≥5 cm Parenchymal laceration >3 cm depth
Any injury in the presence of a splenic vascular injury or active bleeding confned within the splenic capsule Parenchymal laceration involving segmental or hilar vessels producing >25% devascularisation
Any injury in the presence of splenic vascular injurya with active bleeding extending beyond the spleen into the peritoneum – shattered spleen
Vascular injury is defined as a pseudoaneurysm or arteriovenous fistula and appears as a focal collection of vascular contrast that decreases in attenuation with delayed imaging.
Active bleeding from a vascular injury presents as vascular contrast, focal or diffuse, that increases in size or attenuation in the delayed phase
