title: [Rheoencephalographic studies in patients with vertebrobasilar insufficiency].
abstract: Rheoencephalographic investigations in different head positions were carried out in 62 subjects, including 22 healthy ones and 40 patients with vertebrobasilar arterial failure comparing the results with degenerative changes in the cervical spine. In patients with advanced changes in this spine the blood flow in the cerebral vessels was lower and their tonus was greater than in the remaining patients. Rheoencephalographic investigations may be particularly useful in patients in whom vertebral angiography is contraindicated.
