Abstract
The ramification of the pancreatic arteries, including the lobular vessels, was studied in 36 mongrel dogs by means of plastic injection and corrosion, as well as microangiography.The left pancreatic lobe receives the left cranial pancreatic artery and other smaller branches from the splenic artery, and two to four twigs from the gastroduodenal artery. In addition, it receives very often a branch from the common hepatic artery. Branches arising from the cranial mesenteric artery and from the first jejunal artery may also be found. The right cranial pancreatic artery and the right gastroepiploic artery give branches to the pancreatic angle. The arteries to the right pancreatic lobe arise from the cranial and from the caudal pancreaticoduodenal arteries.The interlobular arteries give origin to the intralobular arteries. The penetration and the distribution of the latter vessels differ in lobules of different shape. The intralobular course may be straight or curved. Branches arise generally at acute angles, forming Y or fork‐like patterns, ending into bundles of arterioles.
