Computed tomography blush and splenic injury: does it always require angioembolization?

Area of Science:

• Trauma Surgery
• Diagnostic Imaging
• Radiology

Background:

• Splenic contrast blush on CT scans in blunt trauma is controversial regarding its indication for angioembolization (AE).
• The clinical significance of CT blush in low-grade splenic injuries (AST grades 1-3) requires further elucidation.

Purpose of the Study:

• To determine if CT blush and subsequent angioembolization impact outcomes in blunt trauma patients with low-grade splenic injuries.
• To assess the predictive value of CT blush for patient outcomes under observation.

Main Methods:

• Retrospective review of adult patients with blunt abdominal trauma and splenic injury (AST grades 1-3).
• Analysis of patient groups: observation without CT blush, observation with CT blush, and angioembolization with CT blush.
• Data collected over a 3.5-year period at a Level I trauma center.

Main Results:

• Patients with CT blush who were observed showed no significantly worse outcomes compared to those without CT blush.
• Patients with CT blush undergoing angioembolization did not demonstrate improved outcomes versus observed patients with CT blush.
• CT blush did not predict adverse outcomes in low-grade splenic injury patients managed non-operatively.

Conclusions:

• CT blush in low-grade blunt splenic trauma does not necessitate angioembolization.
• Observation is a safe management strategy for patients with CT blush and low-grade splenic injuries.
• Angioembolization provides no demonstrable advantage for this specific patient cohort.
