Abstract
Different variants of the vertebral artery structure occur with an incidence of no more than 15 %. It is important to note that variant vertebral artery anatomy is usually an incidental finding during instrumental diagnosis, as it is clinically asymptomatic in most cases. However, these variants may be of practical importance either before surgical treatment in the neck or endovascular surgery, as well as during radial diagnostics. In clinical practice, the most common findings are high insertion of the vertebral artery into the foramen of the transverse process, above the level of the VI cervical vertebra, or hypoplasia of one of the vertebral arteries. We present a rare clinical observation of a 12-year-old boy with right vertebral artery doubling at the site V1, who was examined in the Department of Pediatric Neurology with the diagnosis of the mixed type of vegetovascular dystonia. Detailed information about the variants of vertebral artery anatomy is important for all specialists involved in the diagnosis and treatment of patients with cerebrovascular diseases.
