Background: The cystic artery normally arises as a single stem from the right hepatic artery within the Calot’s triangle and crosses neither the common hepatic duct nor the common bile duct. As it approaches the neck of the gallbladder it typically divides into two branches, one of which passes on to the free surface and one on to the attached surface. Liver and biliary related diseases are among the common health problems all overthe world. Methodology: The study was conducted on 100 human liver specimens with intact gallbladder and extrahepatic duct system, collected from the Department of Anatomy and Department of Forensic Medicine, Patna medical college and Hospital, Patna. Study duration of Two years. The specimens obtained were fixed in 10% formalinand were finely dissected. Parameters observed were the source of origin of the cystic artery, its length and diameter, mode and level of termination, relation to the Calot’s triangle and the extrahepatic duct system. Conclusion: The present study adds up to the existing knowledge regarding anatomy and variations of the cystic artery. Knowledge of the normal anatomy and variations of the cystic artery is essential for the surgeons before performing any surgeries on the gallbladder and its duct system.
