Abstract
For this study we used 20 animals that were in the freezer at the Wild Animals Multiplication Center (CEMAS/UFERSA). The animals were thawed, the abdominal cavity was opened, and the thoracic aorta cannulated caudally for the injection of red-stained latex Neoprene 650, and then fixed in formaldehyde solution 10%, for a minimum of 48 hours. Then the animals were dissected, photographed, and the results analyzed. The celiac artery originated from the abdominal aorta and issued the left gastric, splenic, and hepatic arteries. The left gastric artery issued two to three branches to the lesser curvature of the stomach. The splenic artery emitted four branches to the parenchyma of the spleen, six to twelve pancreatic branches and the left gastroepiploic artery. The hepatic artery emitted from one to two pancreatic branches and forked in a short trunk formed by right gastric and own hepatic arteries and in the gastroduodenal artery, which originated the cranial pancreaticoduodenal and right gastroepiploic. The trifurcation behavior of the celiac artery of the yellow-toothed cavy is similar to that found in rodents such as nutria, agouti, hamsters and mice, suggesting that this is the standard for the order.
