Educational Pearls:

• Assessment of head and neck vascular injury due to blunt trauma

• Symptomatic patients require screening head and neck CT angiography

• EAST guidelines include the following criteria for a screening CT angiography in blunt head trauma:

• Unexplained neurological deficits

• Arterial nosebleed

• GCS < 6

• Petrous bone fracture

• Cervical spine fracture

• Any size fracture through the transverse foramen

• LeFort fractures type II or type III

• EAST guidelines include a grading scale for vascular injury:

• Grade I: Luminal irregularity or dissection with <25% luminal narrowing

• Grade II: Dissection or intramural hematoma with >25% luminal narrowing, intraluminal thrombus, or raised intimal flap

• Grade III: Pseudoaneurysm

• Grade IV: Occlusion

• Grade V: Transection with free extravasation
