ADHESION OF THE AORTIC ARCH AND PULMONARY TRUNK IN DOGS (PATHOLOGICAL STUDY)
Cardiac diseases are among the most common pathologies in pets. Congenital heart disorders account for up to 3-5%, and acquired disorders - up to 75% of the total number of heart diseases. Taking into consideration the statistics, in the first instance, the individual, breed and sex features of animals should be taken into account. The German Spitz is a dwarf breed which has been bred since the 18th century. As far as the heart is concerned, one of the most common heart disorders in the German Spitz is open Botallo’s duct. Our research goal was to describe and analyze the pathology of heart vessels in dogs of this breed. The research targets were the heart and blood vessels from a three-year-old German Spitz female that died during the surgery for open aortic duct. The research was carried out at the Altai State Agricultural University. We recorded the adhesion of the walls (by outer coats) of the aortic arch and pulmonary trunk at a distance of 0.5 mm from the ventricular outlets and within 1.2-1.5 cm. Open aortic duct was located between the adherent vessel walls. The adhesion of the aortic arch and pulmonary trunk in the three-year-old dog was accompanied by open Botallo’s duct; after the birth of an animal this is a serious pathology because the arterial and venous blood is mixed.
