Answer

Most patients with extracranial dissection do remarkably well if they survive the initial crisis. As many as 88% of these patients demonstrate a complete clinical recovery at follow-up. However, this suggests an overall risk of death, recurrent transient ischemic attacks, or stroke of approximately 10%.

One series suggests that the severity of neurologic deficits at the time of presentation is related directly to the functional outcome.

Follow-up angiography demonstrates spontaneous healing in as many as two thirds of these patients.
