RESUMO
Detailed descriptions of the abdominal vasculature have not been reported on Puma concolor; thus, herein we provided a thorough description. Our findings include the following: a celiac artery branching into the hepatic and gastrolienal arteries, and this latter further branched into the left gastric, the left gastroepiploic, the lienal and three more arteries that supplied the greater omentum. We also found a cystic artery that derived from the right gastroduodenal artery; a right gastric artery that derived from the right hepatic artery; and an antimesenteric ileal artery that derived from the lateral cecal artery. The right gastric vein did not form the gastroduodenal vein as in other species, but it drained directly into the portal vein. Also, a middle pancreaticoduodenal vein was identified as the last branch of the cranial mesenteric vein. Finally, the left caudal phrenic vein drained into the left renal vein. The abdominal blood supply described herein corresponds to a single individual; further reviews are desirable to corroborate our observations and to detect potential intraspecific anatomical variations.
