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 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.
Distal to this point (the midgut) the arterial supply is from the superior mesenteric artery (SMA), and its branch the inferior pancreaticoduodenal artery supplies the 3rd and 4th sections. The superior and inferior pancreaticoduodenal arteries (from the gastroduodenal artery and SMA respectively) form an anastomotic loop between the celiac ...
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
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 head of the pancreas sits within the curvature of the duodenum, and wraps around the superior mesenteric artery and vein. To the right sits the descending part of the duodenum, and between these travel the superior and inferior pancreaticoduodenal arteries. Behind rest the inferior vena cava, and the common bile duct.
The small intestine receives a blood supply from the celiac trunk and the superior mesenteric artery. These are both branches of the aorta. The duodenum receives blood from the coeliac trunk via the superior pancreaticoduodenal artery and from the superior mesenteric artery via the inferior 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.
