The ocelot (Leopardus pardalis) is a species of wild cat that little has been investigated by their morphology. Thus, the study aimed to detail the origin and distribution of collateral branches from abdominal aorta this animal. We evaluated two exemplary, one male and one female, young, from Paragominas-PA, donated to Animal Morphology Research Laboratory (LaPMA) Federal Rural University of Amazonia (UFRA). The arterial system was filled with red latex and the bodies were preserved with buffered formaldehyde solution 10%. The abdominal aorta of L. pardalis originated between T12 and L1, and the celiac artery was first visceral branch in the craniocaudal direction, resulting in the hepatic a., gastric left a. and splenic a.. The caudal pancreaticoduodenal a., ileal aa., ileocolic aa., right and left renal aa., right and left adrenal aa., and. right and left ovarian aa. or testicular aa. were founded after. Parietally the abdominal aorta yielded an average of six lumbar branches, as well as frenicoabdominal aa., deep circumflex iliac aa. and external and internal iliac aa.. The abdominal aorta still originated the caudal mesenteric a., which is divided into the left colic a. and the cranial rectal a.. The left colic artery followed cranially parallel to the descending colon irrigating it, originating an average of 18 branches, and anastomosing with middle colic a.. The cranial rectal artery followed caudally emerging into eight branches uniting with the final portion of the descending colon and the rectum, together with the rectal middle a.. Finally, the abdominal aorta emerged as the terminal branch, the median sacral. The abdominal arterial vascularization of the ocelot is quite similar to that described in domestic cats, with differences in the number of jejunal arteries and origin of the renal arteries. The abdominal arterial vasculature of this species is quite similar to that described in domestic cats and other mammals, differing in number of the jejunal arteries and origin of the renal arteries. |
