Typically cystic artery arises from the right hepatic artery to the right of hepatic duct in the Calot’s triangle bounded infero-laterally by cystic duct, medially by hepatic duct and superiorly by inferior surface of liver. On reaching the gall bladder it usually divides in to superficial and deep branch. The superficial branch is distributes to the free peritoneal surface of the gall bladder, the deep branch passes behind the gall bladder to became distributed to its attached non-peritoneal surface and to the gall bladder bed.
During the course of routine dissection of celiac trunk and superior mesenteric artery, we found rare anomalous origin of cystic artery, which was taking origin from superior mesenteric artery through its inferior pancreatico-duodenal branch. This kind of anomalous origin of cystic artery, according to our knowledge is rarely reported in any journal of anatomy. In 70% to 80% of individuals, the cystic artery arises as a branch of right hepatic artery within the hepato-biliary triangle. A double cystic artery has been reported to occur in 15% to 25% subjects.
