Spleen trauma

Reviewed and revised 21 December 2015


  • Splenic trauma may result from blunt or penetrating abdominal injury
  • The spleen is the most commonly injured organ in blunt abdominal trauma


  • Abdominal pain, localized tenderness (LUQ)
  • Possible hemorrhagic shock
  • CT abdomen with IV contrast is the investigation of choice (spleen injuries are graded I to V according to severity)


American Association for Surgery of Trauma Organ Injury Scale based on:

  • haematoma size (% surface area)
  • laceration size (parenchymal depth)
  • vessel involvement
  • integrity of spleen
  • vascular status

Grade          Description of Injury

I                       small (<10%, < 1cm)

II                     moderate (10-50%, < 5cm)

III                    large (>50%, > 5cm or expanding)

IV                     large with partial devascularisation (>25%)

V                      complete devascularisation of spleen


  • ATLS approach
  • Most haemodynamically stable injuries can be managed non-operatively (especially Grades I to III)
  • Injuries involving the hilum or avulsion often require surgery (Grade IV or V)
    — haemodynamic instability is the only real contra-indication to conservative management
  • Angiography with embolization should be considered if:
    — a contrast blush is seen on CT
    — AAST grade > III
    — moderate haemoperitoneum is present
    — evidence of ongoing bleeding
  • Patients with functional asplenism will need immunisations and follow up similar to post-splenectomy patients
