This article presents an extremely rare case of a combination of a low-lying lusoria artery and a bicarotid trunkus in a 7-month-old patient with a Fallot notebook. This pathology was established by elective angiocardiography. The diagnostic algorithm for determining the presence of an aberrant right subclavian artery, especially a low-lying one with a retroesophageal course, is of great practical importance in patients not only when correcting congenital heart disease in conditions of artificial circulation, but also when performing systemic pulmonary anastomoses. An incorrectly chosen side for the formation of a systemic pulmonary anastomosis can lead to the creation of a vascular ring around the trachea and esophagus, causing the development of suffocation and dysphagia. In addition, the presence of a bicarotid trunkus, along with an aberrant right subclavian artery with the growth of a child, can cause the development of dysphagia and suffocation, due to compression by the vascular bundle of the anterior wall of the trachea. The paper also presents various variants of the aberrant right subclavian artery, based on the analysis of literary sources.
