Thrombosis of the vertebral artery (Avellis syndrome) involves the spinothalamic tract, nucleus ambiguus, and usually the bulbar nucleus of the accessory nerve. The patient has ipsilateral paralysis of the soft palate and larynx, ipsilateral anesthesia of the pharynx and larynx, and ipsilateral loss of taste. There is contralateral loss of pain and temperature sensation in the trunk and extremities. Ipsilateral Horner syndrome occasionally results.
