Resumo: | Although bovine auricular pavilion has been considered to have large surface vessels, descriptions of its vascularization are scarce. Notwithstanding this region has been used as an alternative route of administration of drugs. With help of an Anatomical specimen, arteriography and dissection have revealed a vast vascular network in the auricle. In this sense, once considered, this knowledge is capable of minimizing prospective complications from the unsuitable use of this region for therapeutic and anesthetic procedures. This study aimed to standardize and describe the arteriography of bovine auricular pavilion in order to acquire a greater knowledge about the local vasculature. Five steers, about one-year-old and weighing about 200 kg, were used, among which three Holstein x Gir crossbred and two Gir purebred. None had lesions in the ear. Of these, two animals were submitted to the standardization of procedures for arteriographies; two others underwent the examination itself. Another bovine, from necroscopy, was subjected to dissection of the ear. The arteriographic images and anatomic dissection pictures were compared to describe anatomical relationships. Arteriography enabled the visualization of lateral, lateral intermediate, intermediate, medial intermediate auricular branches, as well as the medial auricular branch. Conversely, the dissection of the superficial cervicoauricular muscle, between the auricular pavilion and the cornual process base, indicated a poor subcutaneous vascularization of this region, contrasting the rich vascularization near the auricular pavilion. The auricular pavilion arteriography identified a complex vascular network, which in terms of a practical application precludes the administration of slow-absorption drugs in this area. Nevertheless, the dissection images showed the poor subcutaneous vascularization of superficial cervicoauricular muscle surrounding area, making this site more favorable for the administration of long-acting substances. |

Nesse sentido, a arteriografia e a dissecação da região da concha auricular em peça anatômica demostraram a existência de uma vasta rede vascular local, de modo que, se considerado, esse conhecimento é capaz de minimizar possíveis intercorrências oriundas do uso inadequado da região para procedimentos terapêuticos e anestésicos. Este estudo objetivou padronizar e descrever a arteriografia do pavilhão auricular em bovinos, como base para ampliação dos conhecimentos acerca da vasculatura local. Para tanto, foram utilizados cinco bovinos machos, três mestiços (Holandês x Gir) e dois da raça Gir, com aproximadamente um ano de idade, peso médio de aproximadamente 200 kg e sem alterações na aurícula. Destes, dois foram submetidos à padronização dos procedimentos para confecção das arteriografias, dois à execução efetiva do exame e um bovino, oriundo de exame necroscópico, foi submetido à dissecção da região em questão. As imagens do exame arteriográfico e a documentação fotográfica da dissecação anatômica da concha auricular foram confrontadas e descritas as relações anatômicas. Através da radiografia contrastada, foi possível observar os ramos auriculares lateral, intermédio lateral, intermédio, intermédio medial, bem como o ramo auricular medial. Entretanto, a dissecação da área do músculo cérvicoauricular superficial, entre a base do pavilhão auricular e a base do processo cornual, indicou pequena vascularização subcutânea desta região em contraposição com a rica vascularização junto ao pavilhão auricular. A arteriografia do pavilhão auricular identificou uma malha vascular complexa que, em termos de aplicação prática, tornaria o local desfavorável à administração de fármacos que visam lenta absorção. Por outro lado, a dissecação da região adjacente, do músculo cérvicoauricular superficial, demostrou a existência de pequena vascularização subcutânea, conferindo ao local características favoráveis à administração de substâncias de ação prolongada.UEL2017-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2464410.5433/1679-0359.2017v38n5p3039Semina: Ciências Agrárias; Vol. 38 No. 5 (2017); 3039-3048Semina: Ciências Agrárias; v. 38 n. 5 (2017); 3039-30481679-03591676-546Xreponame:Semina.
