The cystic artery supplies oxygenated blood to the gallbladder and cystic duct. In the classic arrangement, occurring with a frequency of approximately 70%, a singular cystic artery originates from the geniculate flexure of the right hepatic artery in the upper portion of the hepatobiliary triangle [1]. A site of origin from a more proximal or distal portion of the right hepatic artery is also considered relatively normal. Latin is an ancient Indo-European language. ... The gallbladder (or cholecyst) is a pear-shaped organ that stores bile (or gall) until the body needs it for digestion. ... The cystic duct is the short (usually around a centimetre or so) duct that joins the gall bladder to the common bile duct. ... Hepatic artery is an artery that distributes blood to the liver, pancreas and gallbladder as well as to the stomach and duodenal portion of the small intestine. ... Elseviers logo Elsevier, the worlds largest publisher of medical and scientific literature, forms part of the Reed Elsevier group. ... Gall bladder Digestive system diagram showing the bile duct The gallbladder (or cholecyst sometimes gall bladder) is a pear-shaped organ that stores about 50 mL of bile (or gall) until the body needs it for digestion. ... The cystic duct is the short (usually around a centimetre or so) duct that joins the gall bladder to the common bile duct. ...


After separating from the right hepatic artery, the cystic artery travels superiorly to the cystic duct and produces 2 to 4 minor branches, known as Calot’s arteries, that supply part of the cystic duct and cervix of the gallbladder before dividing into the major superficial and deep branches at the superior aspect of the gallbladder neck; the superficial passing sub-serously over the left aspect of the gallbladder, with the deep branch running between the gallbladder and gallbladder fossa, terminating at the peritoneum attached to the liver surface. The superficial and deep branches are alternatively known as anterior and posterior respectively.


It must be identified and ligated in operations that remove the gallbladder (cholecystectomies).

Anatomic variation

  • 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 hepatic artery, left hepatic artery, superior mesenteric artery, gastroduodenal artery or retroduodenal artery. Approximately half of superficial cystic arteries have been shown to enter through the hepatobiliary triangle, while deep cystic arteries are often quite small in length and diameter. Tripling of the cystic artery is very rare, occurring in between 0-0.3% of cases.
  • Unusual anatomy of the right hepatic can itself affect the path and form of the cystic artery, with the most frequent variation resulting from an aberrant origin of the right hepatic artery which is described in between 2-16% of cases. Generally this anomalous source is the superior mesenteric artery or more rarely the abdominal aorta, producing what has been described as a “replacing right hepatic artery”, passing through the hepatobiliary triangle and running posterior and parallel to the cystic duct [2]. Because of the close proximity to the gallbladder to the (replacing) right hepatic artery a “caterpillar” or “Moynihan's” hump may form and this artery generally produces multiple short cystic branches rather than a single cystic artery [3].
  • The cystic artery can arise from the left hepatic artery, and in such a case it usually travels through a passage of liver parenchyma, approaching the neck of the gallbladder, before bifurcating into ascending (or superior) and descending (or inferior) branches. This situation is found in roughly 1% of cases. This form of the cystic artery does not pass through the hepatobiliary triangle and has been found located both anteriorly and posteriorly to the common hepatic duct [1].
  • In less than 1% of patients a form known as a recurrent cystic artery is found – the cystic artery arises from the left hepatic artery and passes through either the cholecystoduodenal or cholecystocolic ligaments (connecting the gallbladder to the duodenum and transverse colon respectively), follows the right edge of the hepatoduodenal ligament, and connects to the fundus of the gallbladder before descending to supply the body and neck [1].
  • When a single cystic artery arises from gastroduodenal artery it forms a configuration is known as low-lying cystic artery, as it passes inferior to the cystic duct through the cholecystoduodenal ligament, and therefore remains outside the hepatobiliary triangle [1]. This condition has alternatively been described as an inferior cystic artery and transposition of the cystic artery and duct with a prevalence at approximately 5%. In 25% of these patients with this course there will be a secondary arterial supply to the gallbladder, with the low-lying artery acting as the equivalent of the posterior branch [3].

The superior mesenteric artery arises from the anterior surface of the aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the duodenum and pancreas to the left colic flexure. ... Branches of the celiac artery. ... In animals The parenchyma are the functional parts of an organ in the body (i. ...
