The cystic artery generally comes from the right hepatic artery. [1] Other variants of right hepatic artery includes: arising directly from the proximal or middle part of common hepatic artery, gastroduodenal artery, superior mesenteric artery, celiac axis, aorta, splenic artery, or left gastric artery instead of arising from proper hepatic ...
The supraduodenal artery are 1-2 [1] small [1] [2] arteries which usually [3] arise from the gastroduodenal artery, [2] [3] and sometimes from the posterior superior pancreaticoduodenal arteries, [3] or common hepatic artery. [1] They provide arterial supply to the anterosuperior portion of the proximal duodenum. [3]
The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum, pancreas, and gallbladder. [ citation needed ] It arises from the celiac artery [ 1 ] and has the following branches: [ 2 ]
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'.

Origin. In most (53%) individuals, the RGA arises from the proper hepatic artery. It can also arise from the region of division of the common hepatic artery (20%), the left branch of the hepatic artery (15%), the gastroduodenal artery (8%), and - most rarely - the common hepatic artery itself (4%).
When superficial and deep branches of the cystic artery do not share a common origin, it is defined as a double cystic artery occurring with a frequency of 15%.. The deep branch consistently arises from the right hepatic artery which is generally also the source of origin of the superficial branch, however in some cases it has been found to initiate from the anterior segmental artery, middle ...
The operation is done through a large incision in the upper abdomen. The hepatectomy involves division of all ligamentous attachments to the liver, as well as the common bile duct, hepatic artery, all three hepatic veins and portal vein. Usually, the retrohepatic portion of the inferior vena cava is removed along with the liver, although an ...
The LGA usually arises from (the superior aspect of) the coeliac trunk - sometimes as a terminal branch of a trifurcation, and more rarely as a side branch of the splenic artery or of common hepatic artery. Sometimes it originates directly from aorta or from arteria phrenica inferior. [2]
