Abstract

Assessment of hemodynamic parameters in patients who had transient basilar symptoms suggesting vertebrobasilar insufficiency requires a systematic and accurate detection of brainstem or cerebellar infarcts. Our aim was to detect with (133)Xenon and O-15(2) inhalation methods, a low flow state underlying vertebrobasilar insufficiency in a patient who had no impairment of cerebrovascular control related to infarction of brainstem or cerebellum. A woman with intermittent vertebrobasilar symptoms had an angiogram, magnetic resonance imaging and evaluation of hemodynamic parameters with vertebrobasilar circulation with (133)Xenon inhalation and O-15 inhalation methods MRI failed to show any border-zone or territorial infarcts or degenerative disease. Angiographic study showed significant arterial lesion involving vertebrobasilar vessels. A decrease of blood flow within vertebrobasilar circulation was observed according to (133)Xenon and O-15 inhalation methods. These preliminary results support the view that significant arterial changes within the vertebrobasilar system might account for a low flow state. O-15(2) inhalation method might be in agreement with a previous study performed in vertebrobasilar insufficiency with (133)Xenon inhalation method.
