Cystic artery fundus of the gallbladder before descending to supply the body and neck. 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. 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
