Нарушения Ауторегуляции Позвоночных И Основной Артерий У Пациентов С Вестибулярными Шванномами

We investigated 56 patients with vestibular schwannomas. We researched the cerebral blood flow velocity in the vertebral and basilar arteries. We evaluated the reactivity of cerebral blood flow with use the hypercapnic and hypocapnic functional tests. The average hypercapnic reactivity in patients with vestibular schwannomas in the vertebral artery amounted to 16,73%, in the basilar artery — 21,59%. 35 (62,5%) patients with vestibular schwannomas had the hyporeactivity and 5 (8,92%) patients had areactivity of vertebral artery. The data obtained showed the risk of development of pathological cerebrovascular reactions and ischemic disorders.
