The inferior pancreaticoduodenal artery is a branch of the superior mesenteric artery. [2] These arteries, together with the pancreatic branches of the splenic artery , form connections or anastomoses with one another, allowing blood to perfuse the pancreas and duodenum through multiple channels.
The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'. [1]
These vessels anastomose with the pancreatic branches of the superior and inferior pancreaticoduodenal artery that are given off by the gastroduodenal artery and superior mesenteric artery respectively.
Pancreaticoduodenal artery (arteries to the pancreas and duodenum) can refer to: . Superior pancreaticoduodenal artery; Inferior pancreaticoduodenal artery; In case of a coarctation of the aorta located between the celiac trunk and the superior mesenteric artery, the anastomosis between these arteries can provide an alternative route for blood flow, called the pancreaticoduodenal arcade
The vascular supply of the pancreas is from the celiac artery via the superior pancreaticoduodenal artery and the superior mesenteric artery from the inferior pancreaticoduodenal artery. There are additional smaller branches given off by the right gastric artery which is also derived from the celiac artery. The reason for the removal of the ...
The pancreaticoduodenal veins accompany their corresponding arteries: the superior pancreaticoduodenal artery and the inferior pancreaticoduodenal artery; the lower of the two frequently joins the right gastroepiploic vein.
The dorsal pancreatic artery is a branch of the splenic artery. It anastomoses with the superior pancreaticoduodenal artery and continues as the inferior pancreatic artery on its lower border. [ 1 ]
The inferior pancreaticoduodenal artery is a branch of the superior mesenteric artery. This occurs opposite the upper border of the inferior part of the duodenum. As soon as it branches, it divides into anterior and posterior branches. These run between the head of the pancreas and the lesser curvature of the duodenum.
