- Mechanism of injury involves hyperextension/hyperflexion
- Pathophysiology: inside of the arteries in the neck becomes disrupted, similar to a dissection. This is thrombogenic and leads to cerebral infarction
- Neurologic deficit is common.
- Other risk factors include facial fracture and cervical-spine fracture.
- Treat with anticoagulation – aspirin or other antiplatelet agents are appropriate.
- Increase clinical suspicion when patient presents with neurological deficit and has a negative CT.
