Indeterminate CT Angiography in Blunt Thoracic Trauma: Is CT Angiography Enough?

Abstract

When CTA is indeterminate in blunt thoracic trauma, conventional angiography is unlikely to show an aortic or intrathoracic great vessel injury and may be unnecessary. A grading system for mediastinal hematomas could help triage patients to conventional angiography when further imaging is desired.
