Updates to Article Attributes
Body
was changed:
The American Association for the Surgery of Trauma (AAST) splenic injury grading system is as follows:
-
grade I
- subcapsular haematoma <10% of surface area
- capsular laceration <1 cm depth
-
grade II
- subcapsular haematoma 10-50% of surface area
- intraparenchymal haematoma <5 cm in diameter
- laceration 1-3 cm depth not involving trabecular vessels
-
grade III
- subcapsular haematoma >50% of surface area or expanding
- intraparenchymal haematoma >5 cm or expanding
- laceration >3 cm depth or involving trabecular vessels
- ruptured subcapsular or parenchymal haematoma
-
grade IV
- laceration involving segmental or hilar vessels with major devascularisation (>25% of spleen)
-
grade V
- shattered spleen
- hilar vascular injury with devascularised spleen
NB Advance: advance one grade for multiple injuries up to grade III
