Why is it called the cystic artery?
It lies in the cystohepatic triangle (of Calot), an anatomical space whose borders are formed by the cystic duct, the common hepatic duct and the inferior surface of the liver….Cystic artery.
| Origin | Proper hepatic artery |

| Supply | Gallbladder, common hepatic duct, cystic duct, proximal part of the common bile duct |
What is Moynihan’s hump?
Tortuous course of right hepatic artery, also known as Moynihan’s hump or caterpillar hump is a rare but important anomaly to be recognized to prevent intraoperative vascular and biliary injuries during surgical procedures involving the liver and biliary apparatus.
What is the cystic artery?
The cystic artery is the main artery supplying the gallbladder. It most commonly arises from the right hepatic artery within Calot triangle 1.
Is cystic artery A End artery?
The cystic artery gives off small branches to the cystic duct as well. It is not an end artery; blood supply comes to the gallbladder from the liver in the gallbladder bed also.
What does the gastroduodenal artery supply?
The gastroduodenal artery (GDA) is a terminal branch of the common hepatic artery which mainly supplies the pylorus of the stomach, proximal duodenum, and the head of the pancreas.
What Innervates the gallbladder?
Innervation. The autonomic branches of the hepatic plexus innervate the gallbladder. Small branches of the vagus nerve (CN X) innervate the retroduodenal common bile duct, as well as the hepatopancreatic ampulla of Vater.
What is sphincter of Lutkens?
Helping to regulate bile passage, Lutkens’ sphincter consists of circular muscular fibers at the wall of the cystic duct where it enters the gallbladder.
What is the cystic plate?
The cystic plate is also known as liver bed of the gallbladder and lies in the gallbladder fossa. Two and only two structures should be seen entering the gallbladder.
Where is the gastroduodenal artery?
The gastroduodenal artery (GDA) is a branch of the common hepatic artery that supplies the pylorus of the stomach, superior part of the duodenum, and the head of the pancreas. It is located in the epigastric region of the abdomen, coursing behind the duodenum.
What is the branch of gastroduodenal?
The gastroduodenal artery arising from the common hepatic artery, a branch of the celiac trunk, becomes the superior pancreaticoduodenal artery as it passes behind the first portion of the duodenum. The superior pancreaticoduodenal artery branches into the anterior and posterior superior pancreaticoduodenal arteries.
What is gallbladder structure?
The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen. Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver. The gallbladder is part of the biliary tract.
What is the course of cystic artery?
Cystic artery 1 Course. The cystic artery usually arises from the right hepatic artery within the cystohepatic triangle (of Calot), although its origin can be highly variable. 2 Branches and supply. 3 Anatomical variations.
What is a low-lying cystic artery?
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.
What is the deep branch of the cystic artery?
The deep branch (or posterior branch) runs between the gallbladder and gallbladder fossa, terminating at the peritoneum attached to the liver surface. 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%.
What is a double cystic artery?
Double cystic artery. 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,…
