Splenic Trauma
Diagnosis:
Plain abdominal film
Unreliable andnonspecific
Triad of radiographic
findings in acute
splenic rupture
Left diaphragmatic
elevation
Left lower lobe
atelectasis
Left pleural effusion Radiograph demonstrates a left pleuraleffusion, left basilar atelectasis, and
inferomedial displacement of the
splenic flexure (arrow)

Splenic Trauma
Diagnosis: FAST
Focused AbdominalSonography for Trauma
Bedside study for unstablepatient
15% false-negative
May miss up to 25% of liver
and spleen injuries Compared to CT only 63%
sensitive for detecting freefluid
Fluid in the subphrenic space and
splenorenal recess can be detected.
The image shown demonstrates blood
(arrow) between the spleen (S) and
diaphragm (D).

Splenic Trauma
Diagnosis:
CT with IV contrast
Noninvasive, highlyaccurate, easily
identifies and
quantifies extent of
injury, for stable
patient only
A: Hemoperitoneum with a liver
laceration (arrow) and a
shattered spleen is seen.

Splenic Trauma
Complications
Pseudoaneurysms
Often asymptomatic and
resolve over time If treatment required,
angiographicembolization may beused
Also occur in livertrauma
A. Splenic pseudoaneurysm(arrowheads) after nonoperativetreatment of blunt splenic injury.
B. Successful angiographicembolization The microcatheterused to deploy the coils is markedby the arrowheads and the emboliccoils are marked by the arrows.

Liver Trauma
Blunt trauma is most common
cause of injury to liver
High risk due to:
Large organ, friable
parenchyma, ligamentous
attachments

1 splenectomy (Grade V inj)

Prospective StudyBSLI
An abbreviated protocol of 1 night for Grade I
II injuries and 2 nights for Grade III or higher in
hemodynamically stable pts is safe and
significantly decreases hospitalization c/w
previous APSA recommendations.
