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 large intestine is primarily supplied by the right colic artery, middle colic artery, and left colic artery. They do not supply the duodenum of the small intestine. The duodenum is primarily supplied by the inferior pancreaticoduodenal artery and superior pancreaticoduodenal artery.
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.
One of these, larger than the rest, is sometimes given off near the tail of the pancreas; it runs from left to right near the posterior surface of the gland, following the course of the pancreatic duct, and is called the greater pancreatic artery.
the third part of the duodenum, a segment of the small intestines (can be compressed by the SMA at this location, leading to superior mesenteric artery syndrome). uncinate process of pancreas - this is a small part of the pancreas that hooks around the SMA. The SMA typically runs to the left of its associated vein, the superior mesenteric vein ...
The arterial arcades (intermesenteric arterial anastomoses or Riolan arcades [1]) are a series of anastomosing arterial arches between the arterial branches of the jejunum and ileum.
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 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'.
