Fibromuscular dysplasia of the carotid artery.

A series of 101 patients with carotid fibromuscular disease have been treated and followed for at least one year. Transient ischaemic attacks and amaurosis fugax were the most common presentation, while 22% of patients had had a completed stroke prior to surgery. Graduated dilatation was the most commonly used surgical method. In 150 operations, there were no deaths and three operative strokes. The operative repair has proven to be very durable and associated with a low incidence of neurologic events.
