Aim: To determine the clinical, diagnostic and therapeutic features of Dunbar syndrome in children. Methods: Scientific work was carried out based on the "Republican Children's Clinical Hospital" and the "City Children's Clinical Hospital", Cheboksary. The basis of this study was a survey of 200 children with celiac artery compression syndrome. The results obtained in the course of the work were analyzed on the basis of the Department of Children's Diseases of the I.N. Ulianov Chuvash State University. In addition to routine diagnostic methods, Instrumental methods have been adopted: ultrasound Doppler scanning (Hitachi Vision Avius, Japan), CT angiography (SOMATOM Emotion, SIEMENS (China), Revolution EVO, GE (Russia)) and Magnetic resonance angiography (Optima MR450w 1.5, USA). The duration of the study is short (after surgery) and long-term (up to 2 years). Results: Dunbar syndrome is more often observed in girls, which in 75% of cases is accompanied by signs of chronic abdominal ischemia. Significant and prolonged stenosis of the celiac artery can cause the development of a number of complications (pancreatic-duodenal artery aneurysms, etc.).
