Episode notes
CT Angio Use Has Increased For Trauma
- CT angiograms of the neck are being ordered far more often in trauma than historically, even for less dramatic mechanisms.
- Aaron Lessen attributes this to evolving evidence that minor mechanisms can still cause blunt cerebrovascular injuries (BCVI).
Asymptomatic BCVI Often Causes Delayed Strokes
- BCVI can be asymptomatic initially yet later cause major strokes from clot formation in injured carotids or vertebrals.
- The goal of screening is to identify these silent dissections to prevent delayed in-hospital or post-discharge strokes.
Screen Patients With Cervical Spine Or High Rib Fractures
- Consider CTA for anyone with cervical spine injuries or certain thoracic injuries like multiple high rib fractures.
- These specific injury patterns raise BCVI risk and often prompt clinicians to add neck CT angiography.
