Spleen injury scale

Spleen injuries are graded I-V with increasing severity having higher grading.

Grade I

• Hematoma Subcapsular, < 10% surface area
• Laceration Capsular tear, < 1cm parenchymal depth

Grade II

• Hematoma Subcapsular, 10-50% surface area Intraparenchymal, < 5cm diameter
• Laceration 1-3cm parenchymal depth not involving a parenchymal vessel

Grade III

• Hematoma Subcapsular, >50% surface area or expanding. Ruptured subcapsular or parenchymal hematoma.Intraparencymal hematoma >5cm
• Laceration >3cm parenchymal depth or involving trabecular vessels.

Grade IV

• Laceration Laceration of segmental or hilar vessels producing major devascularization (>25% of spleen)

Grade V

• Laceration Completely shattered spleen
• Vascular Hilar vascular injury which devascularized the spleen

If multiple injuries are present to the liver, then advance the grade by one, up to grade III.
