Abstract

PINTO, Marcos Rogério Alves; RIBEIRO, Antonio Augusto Coppi Maciel  and  SOUZA, Wilson Machado de. The arrangements configured by the coeliac artery in the domestic duck (Cairina moshata). Braz. J. Vet. Res. Anim. Sci. [online]. 1998, vol.35, n.3, pp. 00-00. ISSN 1413-9596.  http://dx.doi.org/10.1590/S1413-95961998000300001.

This research studied the arrangement formed by the celiac artery in 30 domestic ducks, Cairina moshata, 20 males and 10 females. Latex was injected in the arterial system and afterwards samples were fixed with a 10% formol solution. Later samples were dissected to permit better visualization of arterial vessels. The celiac artery leaves the arteria aorta, initially exits the arteria proventricularis dorsalis and the esophagic artery and then continues as two individuals branches: right and left. The left branch sends a vessel that is responsible for the irrigation of the ventral portion of the proventriculus (ventral proventricular artery) and the last end portion of the esophagus; then it sends three other branches to the left lateral portion and cranial border of the ventriculus and emits arteries to the left hepatic lobe. This was found occurring once in 5 samples (16.6% ± 6.8), twice in 14 samples (46.6% ± 9.1) and three times in 8 samples (26.66% ± 8.1). The right branch initially sends out the splenic artery. In 6 samples (20% ± 7.3) two arteries were found, in 12 samples (40% ± 8.9) 3 arteries were noticed and in 1 sample (3.33% ± 3.3) 6 arteries were described. Next it gives out collateral branches to the right hepatic lobe. The number of sent arteries varied from 2 in 21 samples (70% ± 8.4) to 3 in 9 samples (30% ± 8.4). The right branch still emits arteries that go to the left cecum and iliac portion next to it. This occurred with a minimal branch number of 2 in 17 samples (56.66% ± 9.1) or a maximal of 3 in 13 samples (43.33% ± 9.1). The right branch sends 3 more vessels to the lateral portion of the ventriculus, to its caudal margin and to the caudal portion of the piloric junction. After this, the right branch of the celiac artery continues as the pancreaticduodenal artery that irrigates the pancreas and the upper and lower parts of the duodenum.
