Laparoscopic cholecystectomy is the preferred surgical method for symptomatic gallstone disease and
other benign gallbladder diseases Success in laparoscopic cholecystectomy is related to the level of
knowledge about the anatomical structures and congenital anomalies of the biliary tree. In the
literature, during laparoscopic cholecystectomy, 1.9% of patients switched from laparoscopic surgery
to conventional cholecystectomy due to vascular damage. Mortality was observed in 0.02% of cases.
Anatomical landmarks in laparoscopic cholecystectomy have been reported especially as Rouviere’s
sulcus, cystic lymph nodes and arteries. The cystic artery usually originates from the hepatic artery in
1 to 3 branches and is located in the Calot triangle. In 75-80% of reported cases, it passes through the
hepatobiliary triangle or the triangle of Calot. On approaching the gallbladder, the cystic artery
divides into superficial and deep branches. The superficial branch travels below the gallbladder
corpus and the deep branch above the gallbladder. These branches make anostomoses in the
gallbladder parenchyma. The incidence of double cystic artery ranges from 2 to 25-%, but its
occurrence varies among different populations. This situation is associated with the congenital
absence of the deep branch of the cystic artery as a result of developmental changes in the primitive
ventral splanchnic arteries. Recognition of cystic artery anatomy and variations reduces the likelihood
of intraoperative bleeding, biliary injury, and conversion to conventional cholecystectomy.
Consequently, recognition of cystic artery anatomy and variations may reduce the possibility of
uncontrolled intraoperative bleeding and extrahepatic biliary injury and the conversion to
