It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum, and indirectly to the pancreatic head (via the anterior and posterior superior pancreaticoduodenal arteries). The gastroduodenal artery most commonly arises from the common hepatic artery of the celiac trunk, but there are numerous variations of the origin.〔Bergman RA, Afifi AK, Miyauchi R. Variations in Origin of Gastroduodenal Artery. from Anatomy Atlases. (http://www.anatomyatlases.org/AnatomicVariants/Cardiovascular/Images0001/0017.shtml)〕 It first gives rise to the supraduodenal artery, followed by the posterior superior pancreaticoduodenal artery. It terminates in a bifurcation when it splits into the right gastroepiploic artery and the anterior superior pancreaticoduodenal artery (superior pancreaticoduodenal artery). These branches form functional anastomoses with the anterior and posterior inferior pancreaticoduodenal arteries from the superior mesenteric artery. Note that the exact branching of vessels from the gastroduoenal artery is variable. Typically, the posterior and anterior superior pancreaticoduodenal arteries branch independently in that order, but can rarely come of a common trunk. ==Pathology== 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', not least because of the profuse arterial network in the region ensures a high flow rate in the vessel.〔gray 40th, page 1127〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gastroduodenal artery」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
