AAST Splenic Injury Scale

AASTSplenic Injury Scale

Highest Finding (Imaging/OR)

Spleen Injury Grading

Select the highest radiologic or operative finding to determine the AAST severity grade.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

Blunt abdominal trauma (most common cause of splenic injury)

Penetrating trauma involving left upper quadrant

Left lower rib fractures (9th–11th ribs)

Hemodynamic instability with suspected intra-abdominal bleeding

Positive FAST exam showing free fluid in LUQ

CT findings of splenic hematoma, laceration, or vascular injury

Clinical Utility

Guides non-operative management (NOM) vs operative intervention

Determines need for angioembolization in stable patients

Predicts risk of delayed rupture and hemorrhage

Standardizes injury description across trauma systems

Supports trauma registry classification and outcome prediction

Comparison with Related Tools

Tool	Focus	Use Case	Limitation
AAST Splenic Scale	Anatomic grading	Management decisions	No physiology included
Shock Index	Hemodynamic status	Early instability detection	Non-specific
ISS	Global trauma burden	Prognosis	Not organ-specific
AAST Vascular Scale	Vascular injury detail	Adjunct classification	Separate system

Limitations

Does not incorporate hemodynamic status

Does not directly include active bleeding or contrast blush in older versions

Limited predictive value in polytrauma patients

Inter-observer variability in CT grading
