Arterial irrigation of the head and neck of the pampas deer (Ozotoceros bezoarticus, Linnaeus 1758)

Abstract

The pampas deer (Ozotoceros bezoarticus) is a medium-sized deer that weighs 20-40 kg. Historically, it was a widely distributed species that occupied a wide range of open habitats, including pastures, pampas, and Brazilian savanna. However, it is currently considered to be a species at risk of extinction. Anatomical descriptions of the arterial supply are very useful when working with exotic mammals. Knowledge of the locations, the distribution pattern, and the anatomical relationships of the arteries is required when performing any intervention. The objective of this research was to describe the normal arterial distribution pattern in the head and neck of this species. The divisions of the common carotid arteries, to which branches of the vertebral arteries are attached, irrigate the head and cranial parts of the neck. The arterial distribution pattern in the head and neck of the pampas deer was found to be similar to that described for other cervids and bovines but showed important differences from that for the ovine. The pampas deer had a bicarotid trunk, in contrast to other cervids. With regard to domestic animals, the lack of a fully developed internal carotid artery and the marked presence of a linguofacial trunk mean that it resembles the arterial distribution described for bovines.

A comprehensive study on the arterial vasculature of the brain in water buffalo (Bubalus bubalis): Clinical correlates

“…The middle cerebral artery was the largest branch of the arterial circle of the brain in buffalos, similar to that reported in other domestic animals (Frąckowiak & Jakubowski, 2008;Kuchinka, 2017;Skoczylas et al, 2012Skoczylas et al, , 2016Vazquez et al, 2018;Zdun et al, 2013). In none of the cases, a true double middle cerebral artery was confirmed in the arterial circle of the brain of the buffalos.…”

Gross Anatomy of the Heart of Pampas Deer (Ozotoceros bezoarticus, Linnaeus 1758)

“…Cardiac anatomic studies and those related to heart vessels have been performed on both domestic and wild species. [4][5][6][7][8][9][10][11] The studies conducted with Ozotoceros bezoarticus regarding arterial blood supply include the arterial supply of the head and neck, 12 arterial irrigation of the pelvis and the pelvic limb, 13 arterial distribution of the aortic arch, 9 arterial vascularization of the adrenal glands, 8 anatomy of the female reproductive system, 14 anatomy of the male reproductive system, 15 and irrigation of the stomach and intestine. 16 According to our knowledge, there is no anatomical description of the heart of the pampas deer.…”

Features of blood supply to the arteries of the forelimb of the northern domesticated reindeers

“…In this area it gives the general palmar finger-type second and fourth arteries by lateral fingers. At the beginning the arteria goes to the second finger, and only then to the firth finger [5][6][7][8].…”
