Grade | |
|---|---|
I | ● Subcapsular hematoma < 1-cm thick ● Laceration < 1 cm deep into parenchyma |
II | ● Subcapsular hematoma 1–3-cm thick ● Parenchymal hematoma 1–3-cm diameter ● Laceration 1–3 cm deep into parenchyma |
III | ● Splenic capsular disruption ● Subcapsular hematoma > 3-cm thick ● Parenchymal hematoma > 3-cm diameter ● Laceration > 3 cm deep into parenchyma |
IVa | ● Active intraparenchymal and subcapsular splenic bleeding ● Splenic vascular injury (pseudoaneurysm or arteriovenous fistula) ● Shattered spleen |
IVb | ● Active intraperitoneal bleeding |
