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 hepatic vein subsequently drains into the inferior vena cava. The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow. The rest comes from the partially deoxygenated blood from the portal vein. The liver consumes about 20% of the total body oxygen when at rest.
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 gastroduodenal artery most commonly originates from the common hepatic artery, which is a branch of the celiac trunk. Occasionally, it may arise from the proper hepatic artery or from the right or left hepatic arteries, but these are less common anatomical variations.
The hepatoduodenal ligament is the portion of the lesser omentum extending between the porta hepatis of the liver and the superior part of the duodenum. [citation needed] Running inside it are the following structures collectively known as the portal triad: [1] hepatic artery proper; portal vein; common bile duct
The hepatic duct lies in front and to the right, the hepatic artery to the left, and the portal vein behind and between the duct and artery. It also transmits nerves and lymphatics. Sympathetic nerves - these provide afferent pain impulses from the liver and gall bladder to the brain. Pain may be referred to the lower pole of the right scapula ...
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 ...
