title: [Foramen retroarticulare atlantis and the vertebral angiogram (author's transl)].
abstract: The incidence of a foramen retroarticulare atlantis in a group of 380 patients was investigated and put in relation to the frequency of headaches, migraine and Meniere's syndrome. These complaints are found more frequently in patients with a retroarticular foramen. Angiograms of the vertebral artery show vascular constrictions in the region of the foramen retroarticulare in the majority of patients examined. In 5 patients, the clinical symptoms of a mechanical irritation with changes in blood flow through the vertebral artery in the region of a foramen retroarticulare atlantis have been described.
