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.
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 superior and inferior pancreaticoduodenal arteries (from the gastroduodenal artery and SMA respectively) form an anastomotic loop between the celiac trunk and the SMA; so there is potential for collateral circulation here. The venous drainage of the duodenum follows the arteries.
The term "intestinal arteries" can be confusing, because these arteries only serve a small portion of the intestines. They do not supply any of the large intestine. 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.
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
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.
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 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 ]
