Colorado spine surgeon Dr. Donald Corenman discusses veterbrobasilar artery syndrome, also known as vetebrobasilar artery insufficiency, vertebrobasilar artery ischemia and “bowhunters” syndrome. This syndrome is due to a temporary loss of blood flow from the vertebral artery to the base of the brain. This syndrome occurs when the head is rotated to one side causing the artery to become bridged off due to an abnormal spur or ligament.
Symptoms of vertebrobasilar artery syndrome are (when turning the head to the side of the stenosis) is dizziness, vertigo, visual disturbance, nystagmus and ataxia. These symptoms occur because as you turn your head to the side the artery is cut off, which cuts off oxygen to the brain.
This syndrome can lead to a more serious syndrome known as Wallenberg’s syndrome. The symptoms involved with Wallenberg syndrome is infarction of the posterior inferior cerebella artery, sensory loss, dysphagia, dysarthria, ataxia and vertigo.
Colorado spine surgeon, Dr. Corenman analyzes a variety of CT scans of the bowhunters syndrome. This is a case report of a 41 year old male was experiencing dizziness and vertigo when he turned his head to the right. The treatment of this syndrome is generally surgical.
