What is the pancreaticoduodenal artery?
The superior pancreaticoduodenal artery is a branch of gastroduodenal artery that supplies the duodenum and pancreas.
How many pancreaticoduodenal arteries are there?
The inferior pancreaticoduodenal artery has two main branches: Anterior inferior pancreaticoduodenal artery which supplies the anterior aspects of various parts of the pancreas (head, uncinate process) and duodenum (descending and horizontal parts).
Where does the inferior pancreaticoduodenal artery arise from?
superior mesenteric artery
The inferior pancreaticoduodenal artery may arise directly from the superior mesenteric artery or from the first jejunal branch and divides into anterior and posterior branches. The anterior and posterior branches of these vessels form the “pancreaticoduodenal arcades” (Fig. 1).
What is the posterior pancreaticoduodenal artery?
The posterior pancreaticoduodenal artery arises at the upper border of the superior part of the duodenum. It anastomoses with the posterior division of the inferior pancreaticoduodenal artery, supplying the head of the pancreas and the superior and descending parts of the duodenum.
Where is the pancreaticoduodenal artery located?
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.
What does the superior pancreaticoduodenal vein drain into?
The anterior superior pancreaticoduodenal vein runs a horizontal course across the anterior aspect of the pancreatic head before draining into the gastrocolic trunk or the right gastroepiploic vein 1. Both of these subsequently drain into the superior mesenteric vein.
What does the inferior pancreaticoduodenal?
The inferior pancreaticoduodenal artery (the IPDA) is a branch of the superior mesenteric artery. It supplies the head of the pancreas, and the ascending and inferior parts of the duodenum. Rarely, it may have an aneurysm. The celiac artery and its branches; the stomach has been raised and the peritoneum removed.
Where does the superior Pancreaticoduodenal vein drain?
What does the superior pancreaticoduodenal?
The superior pancreaticoduodenal artery is an artery that supplies blood to the duodenum and pancreas.
What does the inferior pancreaticoduodenal artery supply?
The inferior pancreaticoduodenal artery (the IPDA) is a branch of the superior mesenteric artery. It supplies the head of the pancreas, and the ascending and inferior parts of the duodenum. Rarely, it may have an aneurysm.
Where does the SMV drain?
The SMV drains the small intestine, cecum, and ascending and transverse colon via the jejunal, ileal, ileocolic, right colic, and middle colic veins. The IMV drains the descending colon through the left colic, the sigmoid through the sigmoid vein, and the rectum through the superior rectal vein.
Which artery crosses 3rd part of duodenum?
The superior mesenteric artery and vein are anterior to the third part of duodenum. This part may be compressed between the aorta and SMA causing superior mesenteric artery syndrome.
What does the Pancreaticoduodenal vein drain into?
Where does SMV drain?
What does the pancreaticoduodenal vein do?
The pancreaticoduodenal veins accompany their corresponding arteries and act to drain the head of the pancreas and duodenum.
What arteries supply the duodenum?
The proximal segment of the duodenum is supplied by the gastroduodenal artery and its branches which include the superior pancreaticoduodenal artery. The distal segment of the duodenum is supplied by the superior mesenteric artery and the inferior pancreaticoduodenal artery.
