При этом важно отметить, что во время проведения инструментальной диагностики они являются, как правило, случайной находкой, поскольку в большинстве случаев они клинически протекают бессимптомно. В то же время они могут иметь практическое значение либо перед оперативным лечением в области шеи или эндоваскулярной хирургией, а также при проведении лучевой диагностики. В клинической практике чаще всего можно встретить высокое вхождение позвоночной артерии в отверстие поперечного отростка, выше уровня VI шейного позвонка или гипоплазию одной из позвоночных артерий. Мы представляем редкое клиническое наблюдение мальчика 12 лет с удвоением правой позвоночной артерии на участке V 1, проходившего обследование в отделении детской неврологии с диагнозом «вегетососудистая дистония по смешанному типу». Подробная информация о вариантах строения позвоночной артерии имеет важное значение для всех специалистов, участвующих в диагностике и лечении пациентов с цереброваскулярными заболеваниями.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>озвоночная артерия</kwd><kwd>эмбриональное развитие</kwd><kwd>вариантная анатомия</kwd><kwd>ультразвуковое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vertebral artery</kwd><kwd>embryonic development</kwd><kwd>variant anatomy</kwd><kwd>ultrasonography</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">George B.
