Arterial distribution to the pelvic cavity and pelvic limb in the pampas deer (Ozotoceros bezoarticus, Linnaeus 1758)

Abstract

This research is a study about the arterial vascularization of pelvic cavity and pelvic limb in pampas deer. For this study, 25 dead animals were used. The vascularization of the organs was investigated using a latex injection technique. Two animals were injected in the common carotid artery with contrast to cardiac angiography, and then, radiographs were taken. The aorta showed the two external iliac arteries, and after a short course, the aorta ended in two internal iliac arteries. The median sacral artery was originated from the dorsal surface cranially to the emergence of the internal iliac arteries. The last one gave off parietal (iliolumbar, cranial and caudal gluteal arteries) and visceral (umbilical and internal pudendal arteries) branches. The external iliac artery gave as first branch the deep circumflex iliac artery which was divided into a cranial and a caudal branch. After a short distance from the external iliac artery, the femoral and deep femoral arteries were originated. The deep femoral artery gave origin to the pudendoepigastric trunk and to the medial femoral circumflex artery. Based on the arterial distribution of the pelvic cavity and pelvic limb in the pampas deer, it is concluded that the internal iliac artery has a pattern of intermediate development. In reference to the distribution of the external iliac artery and its branches, the pattern of development is the cranial tibial type.

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.…”

Accessory iliolumbar artery- A case report

“…Vazquez N et al dissected the pelvic cavity in Pampas deer and observed two ILA arising as dorsal parietal branches from the IIA. 6 These two arteries arose from a single common trunk, and a similar pattern could be observed in ruminants and swine. 7 In contrast, the human ILA originated from the gluteal cranial artery, similar to feline, equine and rabbit.…”

Anatomic characterisation of the parietal branches arising from the internal iliac artery in the foetal pig (Sus scrofa domestica)

“…Although absence of the common iliac artery has been reported in human subjects, this anomaly is extremely rare [10,25,37]. Interestingly, aplasia of the common iliac artery has also been observed in other artiodactyls, including sheep (Ovis aries) and pampas deer (Ozotoceros bezoarticus) [11,40] and as such, appears to be a phylogenetically defined phenomenon.…”
