The cystic artery most commonly arises from which hepatic artery?

• A. Right Hepatic Artery
• B. Left Hepatic Artery
• C. Proper Hepatic Artery
• D. Gastroduodenal Artery

Answer: (A)

The main idea is how the gallbladder gets its blood supply. The cystic artery, which feeds the gallbladder, most commonly comes off the right hepatic artery. The right hepatic artery is a branch of the proper hepatic artery, and within Calot’s triangle it often gives a cystic branch that travels with the cystic duct to supply the gallbladder. This proximity explains why that artery is the typical source.

There are variations, but they are less common. Occasionally the cystic artery may arise from the hepatic artery proper, or even from the left hepatic artery, or rarely from the gastroduodenal artery. However, the most frequent origin remains the right hepatic artery.
