The aim of the study was to determine characteristics of the morphometric parameters of the abdominal part of aorta and its unpaired branches in adult men with different body types. Material and methods. An analysis of 148 computer tomograms of the abdominal aorta and its unpaired branches was carried out in adult men aged 25-75 years with a different body type. According to the classification V.N. Shevkunenko, three groups with dolichomorphic, mesomorphic and brachymorphic types were distinguished. According to the Pigne Index, asthenic, normostenic and hypersthenic body types are distinguished. Results. It was established that the diameter of the abdominal aorta at the level of the celiac trunk does not differ depending on the body type according to V.N. Shevkunenko, in groups identified by the Pigne index, the diameter of the abdominal aorta differs at all levels. The length of the abdominal aorta has significant differences only between extreme forms of body type - dolicho- and brachymorphic, as well as between hyper and asthenic. When using the index V.N. Shevkunenko from the studied angular parameters reliably differs only the angle of discharge of the superior mesenteric artery, in groups systematized by the Pigne index, differences are observed in all angular parameters. Conclusion. Due to the fact that the classification of V.N. Shevkunenko reflects to a greater degree the linear parameters of the body, and the Pigne index is also voluminous (chest girth, body weight), the latter provides a greater number of differences in the compared parameters of the abdominal aorta and its unpaired branches, including those depending on the type and degree of development of the abdominal fatty tissue.
