[The results of Doppler ultrasonic study of major cerebral vessels in patients with migraine].
Forty-three patients with migraine have been studied. A diagnosis was made according to the criteria of International Headache Classification. Parameters of the blood flow linear velocity, reactivity of the extracranial and intracranial vessels and the presence of the extravasal compression of the vertebral arteries have been investigated. The changes of the vertebral basilar arteries were observed in 45% of the patients that can be considered as a predisposing factor. The alterations of cerebrovascular reactivity and venous outflow have been recorded. These data were not consistent during the attack and quiet period and differed in the groups of patients with and without aura. The data obtained confirm that migraine attack is the result of the compensation failure of the cerebral arteries tone regulatory mechanisms.
