SPECIFIC PECULIARITIES OF ARTERIAL VASCULARIZATION SOURCES OF ITALIAN
Abstract
The paper explores the peculiarities of arterial blood supply of Italian goose’s esophagus. The authors applied methods of general and fine-scale section and angiography for conducting the research. The researchers investigated five carcasses of geese. The authors found out that ascending and descending esophageal arteries and branches of esophageal and tracheobronchial artery are the sources of esophageal vascularization. The authors outline the areal segmentation of esophagus and extremely high vessel compliance with high compensation abilities. Additional links between ascending and descending esophageal arteries with arcs and anastomoses contribute to normalization of blood pressure inside the paries. Ascending and descending esophageal arteries are directed towards each other and anastomose with each other. Arteries root from them on the dorsal surface of esophagus and join esophagus at an acute or obtuse angles to the adventitia at the bone segment level. Ascending and descending esophageal arteries are the sources of vascularization of the primary and secondary parts of esophagus; abdominothoracic part receives blood from the branch rooting from esophageal and tracheobronchial artery. The authors highlight extremely high vessel flexibility with compensation abilitites, additional links between ascending and descending esophageal arteries with arcs and anastomoses contribute to normalization of arterial blood pressure inside the paries. The research contributes to detail classification of arteries branching peculiarities in Italian goose’s esophagus.
