[Cardiac morphometry and distribution of coronary arteries in New Zealand rabbit (Oryctolagus cunniculus).] Morfometria cardíaca e distribui- ção das artérias coronárias em coelhos Nova Zelândia (Oryctolagus cunniculus).

E-mail: marceloabidu@gmail.com The rabbit heart has been frequently used as an experimental model to study regional ischemia. However some aspects of their macro anatomy still need a more detailed description, especially the cardiac arterial vascular system, which has a huge variability in distribution and trajectory. Thirty cadaveric adult New Zealand rabbits, 15 of each sex, with an average weight and rostrum-sacral length of 2.5 kg and 40 cm, respectively, were used. The thoracic aorta was cannulated and the vascular system was filled with stained latex S-65. The aim of this study was to determine the cardiac morphometry and main branches of the coronary arteries in New Zealand rabbits. The left coronary artery showed a bifurcation pattern with paraconal interventricular and left ventricular marginal branch in 86.66% of males and 93.33% of females and a trifurcation pattern with paraconal interventricular, left ventricular marginal and left circumflex branch in 13.33% of males and 6.66% of females. The paraconal interventricular branch occupied the groove of the same name in 13.33% of males and 46.66% of females. The sinuous interventricular branch occupied the groove in only 20% of males. This study showed no statistical difference between the measurements of height, width and thickness of the heart between both sexes.

No entanto, alguns aspectos de sua macro anatomia ainda precisam de uma descrição mais detalhada especialmente o sistema vascular arterial cardíaco, que apresenta variabilidade na distribuição e trajeto. Trinta cadáveres de coelhos adultos da raça Nova Zelândia, 15 de cada sexo, com peso médio e comprimento rostro-sacral de 2,5 kg e 40 cm, respectivamente, foram utilizados. A aorta torácica foi canulada e o sistema vascular foi preenchido com látex coradas S-65. O objetivo deste estudo foi determinar a morfometria cardíaca e as ramificações principais das artérias coronárias. A artéria coronária esquerda se bifurcou em ramo interventricular paraconal e marginal ventricular esquerdo em 86,66% dos machos e 93,33% das fêmeas e trifurcou em ramo interventricular paraconal, marginal ventricular esquerdo, circunflexo esquerdo em 13,33% dos machos e 6,66% das fêmeas. O ramo interventricular paraconal coincidiu com o sulco de mesmo nome em 13,33% dos machos e 46,66% das fêmeas. O ramo interventricular subsinuoso coincide com o sulco apenas em 20% dos machos. Na presente pesquisa não houve diferença estatística entre as medidas de altura, largura e espessura do coração entre ambos os sexos.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2014-06-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/506Brazilian Journal of Veterinary Medicine; Vol. 36 No. 2 (2014); 159-166Revista Brasileira de Medicina Veterinária; v. 36 n. 2 (2014); 159-1662527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVporhttps://rbmv.org/BJVM/article/view/506/381Oliveira, Mariana Correiade Oliveira, Igor Monteiro SenraRoza, Magno SantosFigueiredo, Marcelo Abiduinfo:eu-repo/semantics/openAccess2020-12-23T17:32:15Zoai:ojs.rbmv.org:article/506Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2020-12-23T17:32:15Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
