Common questions
What does Splenic Injury Grading (AAST 2018) do?
Use in blunt abdominal trauma to assign a splenic injury grade and frame management — nonoperative monitoring, angioembolization, or surgery — always interpreted against hemodynamic stability.
How is the result calculated?
Grade by the most severe finding (subcapsular/intraparenchymal hematoma size, laceration depth, vascular injury). I–II usually NOM; III NOM ± embolization; IV–V or instability → embolization/surgery.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
