“…The first type corresponds only to the brachiocephalic trunk arising from the aortic arch and from the right and left common carotid arteries and the right and left subclavian arteries arise. This type has already been described in the laboratory rat ( Rattus norvegicus ; Hebel & Stromberg, ), buffalo ( Bubalus bubalis ; Cortellini, Machado, Oliveira, Miglino, & Artoni, ), capybara ( Hydrochoerus hydrochaeris ; Culau, Reckziegel, Lindemann, Araújo, & Balzaretti, ), grey brocket ( Mazama gouazoubira ; Schimming, Matteis, Silva, & Guazzelli Filho, ), domestic cow ( Bos taurus ) and horse ( Equus ferus caballus ; Dyce, Sack, & Wensing, , p. 1585).…”

“…A second trunk called the brachiocarotid was reported in capybaras by Culau et al (), which gives rise to the right common carotid and right subclavian arteries. This trunk originates from the brachiocephalic trunk, and this structure was also observed in some species, such as the paca (Leal et al, ; Oliveira et al, ), ocelot ( Leopardus pardalis ; Martins et al, ) and the New Zealand rabbit ( Oryctolagus cuniculus ; Souza, Bavaresco, & Campos, ), but the authors do not call it a brachiocarotid trunk but rather the common trunk for the right common carotid artery and right subclavian artery.…”

The aortic arrangement is an important structure associated with the maintenance of homeostasis. Based on this information, this study was conducted to describe the collateral arteries of the aortic arch of Antillean manatee and define the standard model for the species. Three specimens, an adult male, adult female and a male neonate, all strandings on the coast of the state of Rio Grande do Norte, Brazil, were used. The study was performed in the Laboratory of Morphophysiology of Vertebrates of the Federal University of Rio Grande do Norte, where in situ photographs were taken to demonstrate their topography. Subsequently, their hearts were removed and fixed in 10% formaldehyde and after 72 hr were dissected and analysed, obtaining schematic drawings and photographs of the vascular arrangement. The aortic arch was represented by three collateral arteries identified as the brachiocephalic trunk, left common carotid artery and left subclavian artery. This arrangement was similar to that found for other sirenians, and yet, for other mammals like hooded seal, murine, margarita island capuchin, black‐handed tamarin, Mongolian gerbil and human. The morphological similarity presented in this study with different species of mammals, including humans, may contribute valuable information from an evolutionary point of view.

“…Na literatura, encontram-se estudos que descrevem os ramos colaterais do arco aórtico de espécies de mamíferos domésticos e silvestres, estudos estes que caracterizam as principais artérias que emergem diretamente do arco, seus respectivos ramos, e assim, classificando os diferentes tipos de arranjos vasculares do arco aórtico para cada espécie (Tabela 1). Basicamente já foram descritos, mais frequentemente, três diferentes tipos de arranjos, o primeiro tipo corresponde apenas o tronco braquiocefálico surgindo do arco aórtico e a partir deste surgem às artérias carótidas comum direita e esquerda e as artérias subclávias direita e esquerda, descrito desta forma no rato de laboratório [17], búfalo [8], capivara [9], veado-catingueiro [32], em bovinos e equinos [11]. Já o segundo tipo, caracteriza-se pelo surgimento de duas artérias, sendo estas, o tronco braquiocefálico, seguido da artéria subclávia esquerda, e [10,33], camundongo [7], sauim [4] e no macaco-prego [14].…”

“…Um segundo tronco chamado de braquiocarotídeo foi descrito em capivaras [9], que dá origem às artérias carótida comum direita e subclávia direita, este tronco tem origem do próprio tronco braquiocefálico, e em algumas espécies como é o caso da paca [21,26], jaguatirica [24] e do coelho Nova Zelândia [34], também foi observado esta mesma estrutura, porém os autores não chamaram de tronco braquiocarotídeo e sim de tronco comum para as artérias carótida comum direita e subclávia direita. Esta angioarquitetura não foi evidenciado nos animais desta pesquisa.…”

Background: Gerbils (Meriones unguiculatus) are rodents belonging to the Muridae family. Recently, breeding of this species as pets has increased significantly. Animal models are being investigated to study diseases related to the human aortic arch. Despite the importance of the aortic arch in maintaining homeostasis, there is limited data available regarding its morphology in gerbils. This study was performed with the objective of describing the collateral branches of the aortic arch in this animal to establish a standard model and thus contribute to future research on cardiovascular diseases in humans.Materials, Methods & Results: This study used 20 male specimens from previous studies that were frozen and stored at the Laboratory of Veterinary Anatomy of the Federal Rural University of the Semi-Arid Region. After thawing the animals, the thoracic cavity was opened for aortic cannulation. The vascular system was washed using saline solution and Neoprene latex stained with red pigment was injected. Subsequently, the animals were fixed in 10% formaldehyde and were dissected and analyzed 72 h later. The arrangement of the collateral branches of the aortic arch in gerbils was analyzed in all animals. The brachiocephalic trunk, the left common carotid, and the left subclavian artery were observed to originate as collateral branches. The brachiocephalic trunk bifurcated into the right common carotid and the right subclavian arteries. The right and the left subclavian arteries branched into the vertebral artery, the internal thoracic artery, the superficial cervical artery, the costocervical trunk, and the axillary artery.Discussion: Several studies reported in the literature describe the collateral branches of the aortic arch in domestic and wild mammalian species. These studies examined the main arteries that originate directly from the aortic arch and their respective branches, and classified the different anatomical variants of the aortic arch in each species. Three different arrangements have been commonly described. The first type corresponds only to the brachiocephalic artery originating from the aortic arch. The right and the left common carotid arteries and the right and the left subclavian arteries originate from this brachiocephalic artery. This type has already been described in the laboratory rat, catingueiro-deer, cattle, and horses. The second type is characterized by the presence of 2 arteries - the brachiocephalic trunk and the left subclavian artery. The right and the left common carotid arteries and the right subclavian artery originate from the brachiocephalic trunk. This arrangement has been reported in most species already studied such as rodents including the paca, chinchilla, guinea pig, mocó, nutria and the preá. The third type of vascular arrangement is observed in the gerbil. In this species, 3 collateral arteries originate from the aortic arch (the brachiocephalic trunk, the left common carotid, and the left subclavian artery). The right common carotid and the right subclavian artery originate from the brachiocephalic trunk. This vascular model has been described in the manatee, in humans, mice, sauim, and the monkey-nail. Thus, we concluded that the branching pattern of the aortic arch of the gerbil was characterized by the brachiocephalic trunk, the left common carotid, and the left subclavian artery, as has been described in mice, the manatee, monkey-nail, sauim, and humans. Based on these morphological characteristics, gerbils could serve as potential experimental models to study diseases related to the human aortic arch.

“…brachiocephalicus), left common carotid artery (a. subclavia sinister) and the left subclavian artery (a. subclavia sinister). Another particular situation is encountered in capybara [8], where the brachiocephalic trunk is the only collateral branch detached from the aortic cross. A similar situation was reported by in rabbit [26], guinea pig [25] and squirrel [3].…”

Background: The investigation on the cardiocirculatory system in chinchilla has become increasingly important due to the use of the species in experimental medicine (toxicology, pathology, parasitology etc.). Even though initially this species was regarded with a strict economic interest, in the last period, chinchillas have become an increasingly-encountered patient in veterinary clinics and hospitals. Another aspect is the use of the species in medical research, as experimental model or in parasitology. The present study tackles a combined anatomical and radiological (angiographical) study to accurately describe the vascular anatomy of the initial part of the aortic arch (Arcus aortae).Materials, Methods & Results: The anatomical distribution of collaterals detached from arcus aorticus (brachiocephalic trunk and subclavian arteries) are highlighted in this paper. To do that, the classical stratigraphic anatomical investigation, followed by the radiological study with the help of the contrast substance injected into the vascular bed were used in combination. Several Chinchilla lanigera female carcasses, obtained from a private commercial farming unit in Cluj county, Romania were used for this study. Ten carcasses were used for the anatomical study, being injected into the vascular bed with a mixture of latex and acrylic dye, fixated into formaldehyde 5% and later dissected, while the other ten carcasses were injected at the level of the aortic arch with Visipaque 320 contrast substance and subjected to the angiographical procedure.The anatomical investigation was carried after an initial 5 day-fixation period, while the angiographic procedure was initiated using the TEMCO Grx-01 device and the Veterinary Digital Imaging System® as digital imaging processing software. This combined study shows the differential mode of emergence of the subclavian and carotid arteries in this species. The brachiocephalic trunk is the first large collateral branch arising from the initial part of the aortic cross while the left subclavian artery, in all studied cases, stems from this initial part of the aortic arch. The right subclavian artery arises from the terminal part of the brachiocephalic trunk, at the cranial border of the first rib. The continuation of the trunk is represented by right common carotid artery that follows the right jugular groove. The left common carotid artery emerges at the medial aspect of the first intercostal space as a collateral branch detached from the brachiocephalic trunk, in its initial sector. In respect to the collaterals emerging from the subclavian arteries, our study showed that in all studied cases, four branches arise in sequence- the internal thoracic, dorsal scapular, vertebral and superficial cervical arteries. The existence of the common trunks (internal thoracic, dorsal scapular arteries and superficial and deep cervical arteries (as described by other authors) was not confirmed on the investigated specimens.Discussion: The paper highlights some interesting facts referring to the specific morphology of the aortic arch in chinchilla, as literature data provides some divergent data. Some of the aspects noted are confirmed (the emergence of subclavian arteries) while some others are still subjects to discussion and further investigation (collateral branches of subclavian arteries). Our approach focuses also on the comparative aspects of the morphology of the branches emerging from the aortic arch. According to the available literature, the following species were used as comparison: leporids, Guinea pig, squirrel, yellow-necked mouse, Egyptian mouse, rat, armadillo, nutria, capybara, paca, fox and leopard.
