Figures
- Figure 1
Pseudoaneurysm (arrow) noted on initial CT scan.
- Figure 2
Selective angioembolization of bleeding splenic vessel (arrow).
- Figure 3
Specimen shows embolized portion of spleen as dark area (arrow). Bleeding occurred from splenic hilum.
- Figure 4
Transverse image of spleen with pseudoaneurysms in the upper pole. Contrast is poorly timed as neither the aorta nor pseudoaneurysm appear bright.
- Figure 5
Repeat CT scan showing splenic hematoma and extraparenchymal pseudoaneurysm (arrow).

Adaptation of AAST Organ Injury Scale for Spleen
Grade Injury type Description of injury I Hematoma
LacerationSubcapsular, <10% surface area
Capsular tear, <1 cm parenchymal depthII Hematoma Subcapsular, 10% to 50% surface area
Intraparenchymal, <5 cm in diameterLaceration Capsular tear, 1 cm to 3 cm parenchymal depth that does not involve a trabecular vessel III Hematoma
LacerationSubcapsular, >50% surface are or expanding: ruptured subcapsular or parenchymal hematoma: intraparenchymal hematoma_>5 cm or expanding
3 cm parenchymal depth or involving trabecular vesselsIV Laceration Laceration involving segmental or hilar vessels producing major devascularization (>25% of spleen) V Laceration
VascularCompletely shattered spleen
Hilar vascular injury with devascularizes spleenAdapted from American Association for the Surgery of Trauma organ injury scale for spleen.
