Artéria renal dupla em gato

Abstract

ResumoO conhecimento das variações nos vasos renais possui importância em um programa de sistematização da anatomia radiológica e cirúrgica, tanto para o homem quanto para animais destinados a pesquisa, ensino e treinamento cirúrgico. As artérias renais têm sido estudas tanto radiograficamente quanto através de dissecção. Atenção particular é dada ao estudo desses vasos enfatizando as variações entre as diferentes espécies animais. O local de origem das artérias renais a partir da aorta abdominal varia de acordo com a topografia renal nos diferentes animais. A artéria renal direita se origina mais cranialmente que a esquerda de acordo com a posição mais cranial do rim direito. O objetivo deste artigo é descrever um caso de dupla artéria renal esquerda originando-se da superfície ventral da artéria aorta abdominal em um cadáver de gato macho com três anos de idade. O mesmo foi fixado e preservado com solução de formaldeído a 10% e teve o seu sistema arterial preenchido com látex corado. Observou-se que o rim esquerdo foi suprido por duas artérias renais, de diferente topografia e arranjo, caracterizando duplicidade da artéria renal.

Renal arteries have been considered by dissective or angiographic study means. Particular attention has been paid to the study of these vessels, outlining the variations noticed among various animal species. The renal arteries sites of origin of the abdominal aorta vary according to the renal topography of the different animals. As a rule, the right artery arises more cranially than the left one, according with the most cranial position of the right kidney. Thus, the goal of this article is to describe a case of a left double renal artery originating from the ventral portion of the aorta, in a three old male cat cadaver, formalin-preserved at 10% and with latex colored vascular injection. It was observed that the left kidney was supplied by two arteries of different topography and arrangements, showing duplicity of the renal artery.

Renal morphological description of brown brocket deer, Mazama gouazoubira, Fisher 1814 (Artiodactyla; cervidae)

“…The renal arteries (right and left) of the brown brocket deer were bifurcated in two main sector arteries, cranial and caudal; this renal artery pattern was described to the crabeating raccoon (Barcelos et al, 2012) and ovines (Carvalho 2007). The organ did not present accessory renal arteries or double renal arteries, supporting the anatomical findings from Research, Society andDevelopment, v. 9, n. 10, e4929108868, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i10.8868 caprines (Abidu-Figueiredo et al, 2009), dogs (Alonso & Abidu-Figueiredo 2008) and cats (Pestana et al, 2011).…”

Intraspecific anatomical variations of the extensor tendons of the carpus and digits with a reexamination of their insertion sites in the domestic dog (Canis lupus familiaris): a cadaveric study

“…We noted the presence of the BR bilaterally and unilaterally respectively in 18 (53%) and 5 (14.7%) of the 34 dogs dissected compared with 40 (40%) bilateral and 15 (15%) unilateral of the 100 dogs dissected by Pestana et al [ 61 ], 110 (33.74%) bilateral and 65 (19.94%) unilateral of the 326 dogs dissected by Santos Junior et al [ 62 ], and 35 (38.9%) of the 90 dogs dissected by Wakuri and Kano [ 63 ]. The insertion of the BR muscle was variably attached through a long and distinct tendon (Fig.…”

Duplicity of caudal vena cava and renal veins in a Brazilian shorthaired cat - a case report

“…Numerical variations of the renal arteries have been described in dogs (OLIVEIRA and GUIMARÃES, 2007;ALONSO and ABIDU-FIGUEIREDO, 2008), cats (PESTANA et al, 2011), andrabbits (ALMEIDA et al, 2013). These reported variations are more frequently observed in arteries than in veins, although CAMPOS et al (2014) and STOCCO et al (2014) reported double renal veins in both kidneys, and triplet veins in only the right kidney, in cats, respectively.…”
