Long-term follow-up study (more than 5 years) after posterior fossa revascularization was performed. Among 8 patients operated with superficial temporal artery to superior cerebellar artery anastomosis, 6 survived. Clinical improvement during follow-up period was obtained in 4. No recurrent ischemic attack was noted. Among 8 patients treated with extracranial vertebral artery reconstruction, 5 survived. No recurrent attacks of the posterior fossa ischemia was demonstrated. The causes of death were diabetes-associated supratentorial stroke, cardiac failure, pneumonia etc.
