The hepatic artery proper arises from the common hepatic artery and runs alongside the portal vein and the common bile duct to form the portal triad.A branch of the common hepatic artery –the gastroduodenal artery gives off the small supraduodenal artery to the duodenal bulb.
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]
proper hepatic artery, an arteriole branch of the hepatic artery that supplies oxygen; hepatic portal vein, a venule branch of the portal vein, with blood rich in nutrients but low in oxygen; one or two small bile ductules of cuboidal epithelium, branches of the bile conducting system. lymphatic vessels; branch of the vagus nerve
hepatic artery proper; portal vein; common bile duct; Manual compression of the hepatoduodenal ligament during surgery is known as the Pringle manoeuvre. [citation needed] The cystoduodenal ligament is also found in the lesser omentum and is distinct from both the hepatoduodenal and hepatogastric ligaments.
It transmits the following (in anterior to posterior order): common hepatic duct (leaving); proper hepatic artery (entering); hepatic portal vein (entering); 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.
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.
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 ...
