[Means of experimentally reproducing the vertebral artery syndrome]

The authors suggest a method of reproducing the syndrome of vertebral artery in a chronic experiment on dogs. Two horse-shoe electrodes connected with the wires exteriorised to the posterior surface of the neck are introduced and fixed under general anesthesia at the selected level into the vertebral artery. Rheographic and thermometric shifts occurring in response to the electrode stimulation and to dosaged electrical stimulation were studied.
