About the ramification of the celiae and cranial mesenteric arteries in cats (Felis catus domestica)

Abstract

The arterial branches with emerge from the celiac and cranial mesenteric arteries were studied in 25 male and 25 female outbreed young and adult cats. The hepatic artery was found to be the first and most frequent (90.0%± 4.2) colateral of the celiac artery followed by the gastrolienal branche composed by both the left gastric and the lienal artery. In only (8,0% ± 3,8) of the cases both the hepatic and left gastric artery was found to originate in a common branch. In only one animal (2.0% ± 2.0) the tripus coeliacus was observed. In 28 of the studied animals (56.0% ± 7.0) the caudal pancreatico duodenal artery was seen to emerge, as the first colateral, from the cranial mesenteric artery, followed by the medial colic artery wich in 4 % of the cases emerged making a common branch with the ileocecocolic artery. In 17 times (34-0% ± 6.7) the medial colic artery appeared ahead from, and in the remaining 5 animals (10.0% ± 4-2) at the same area of the emergency of the pancreatico duodenal artery. In all the cases, excepting the two above observations already mentioned, the ileocecocolic artery and branches of the jejunal arteries, emerge after both the pancreatico duodenal artery and medial colic artery. Some vessels were observed emerging from the celiac artery. It was also found some variability related to the origin of the first and second jejunal branches.
