The Cystic Artery
The gallbladder is supplied by the cystic artery. The cystic artery is usually a branch of the right hepatic artery but can also originate from left or common hepatic arteries, the gastroduodenal artery, or directly from the celiac trunk.

The cystic artery passes superior to the cystic duct and terminates in two branches called the anterior (superficial) branch that runs on the free wall of the gallbladder and the posterior (deep) branch that runs on hepatic aspect of the gallbladder close to the gallbladder fossa. The cystic duct is supplied by 2 to 4 minor branches called Calot?s arteries that originate just proximal to the origin of the anterior and posterior vessels.

The vessel for most of its course runs in the triangle of Calot whose boundaries are the inferior border of the liver edge, cystic duct, and common hepatic duct.
Calot’s Triangle |
|
Calot’s triangle is an anatomic space bordered by the common hepatic duct medially, the cystic duct inferiorly and the liver superiorly. The cystic artery usually passes through the triangle, and Calot’s lymph node is also within this triangle. It is an important landmark to recognize during laparoscopic cholecystectomy gallbladder Copyright 2012 Courtesy Ashley Davidoff 04766b05b04.57dk.8s |
Small arteries, veins and biliary radicles run between the liver and the gallbladder in the gallbladder fossa directly from the liver into the gallbladder.
Arteries, Veins, and Lymphatics in the Gallbladder Fossa |

The histological section of the gallbladder fossa shows the relatively large thick walled branch of the deep cystic artery, (red) abutting the liver (upper portion purple) accompanied by venules (blue) and lymphatics. (yellow) The veins drain directly into the fossa and connect with intrahepatic portal branches of the segment V and IV of the liver. gallbladder gallbladder fossa gbf venules arterioles liver connective tissue hilum of the gallbladder venous drainage blood supply Copyright 2012 Courtesy Ashley Davidoff MD 00140c03.8s |

Variations
In about 15% of patients the anterior and posterior arteries have separate origins and this entity is called double cystic artery. An example is seen below.
Double Cystic Artery – Separate Origins Off the Right Hepatic Artery |
| This is the angiogram of a 52 year old male with HIV cholangiopathy and cryptosporidium associated with a neoplastic mass in the CBD, and a fistula between the CBD and duodenum presents with uncontrolled hemobilia. Embolization of the gastroduodenal artery was successful. The follow up angiogram shows the catheter in the GDA which has been occluded by coils, a stent in the CBD, and flow in the cystic circulation.

Other variations of the origin of the vessel include its origin from the left or or common hepatic artery, and it can course either anterior to or posterior to the common hepatic duct
