Variations of the arterial supply of the duodenum and the pancreas in the domestic cat (Felis domestica brisson).

We found that there are variations of the arterial supply of the duodenum and the pancreas in the domestic cat. In not a single cat does the cranial pancreatico-duodenal artery supply the whole descending duodenum. In 80% of our cases it supplies the cranial half, and in 20% of our cases only the cranial third of the descending duodenum. Only 48% of our cases is the caudal pancreaticoduodenal artery the first branch of the cranial mesenteric artery. But in 52% of our cases it is the second or even the third branch of the cranial mesenteric artery.
