Right coronary artery of the Eurasian lynx

Abstract

The Eurasian lynx is widely popular among wild feline animals. It is often the object of domestication and it is bred on fur farms for the extraction of fur products. Heart vascularization in domestic and wild mammalian animals has not been studied enough and is still an urgent area of research, our goal was to study the anatomy of the left coronary artery of the Eurasian lynx heart and establish its anatomical and topographic patterns. To study the anatomy of the heart, the corpses of the Eurasian lynx were taken at the age of two or three years. In total, five corpses of the Eurasian lynx were examined. Cadaver material was delivered from private fur farms of the Leningrad and Moscow regions to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. To study the vascularization of the heart of the studied animals, classical and modern anatomical techniques were carried out, such as fine anatomical dissection and the manufacture of corrosive preparations using latex. According to the results of the study, it was found that the left coronary artery in the Eurasian lynx is sufficiently developed and supplies blood to the structures of the left and right half of the heart, and the subsinuous artery does not belong to the branches of the left coronary artery, in connection with which it can be concluded that the uniform type of blood supply in the Eurasian lynx. The results of the study can be used by veterinary specialists, in particular surgeons, to establish operative access to the heart in the form of a pattern of branching of the left coronary artery of the heart in the Eurasian lynx.
