Calot’s triangle is considered to be the important reference area for biliary surgeries and the cystic artery is usually given off by the right hepatic artery inside the triangle. Variations are more frequent in origin, course and length of the cystic artery. Hence this study aimed to study the normal as well as the variations of cystic artery with its relation to the calot’s triangle.
Materials and methods
The study was conducted in 40 adult human cadavers by dissection method in Madras Medical College, Chennai.
Out of 40 cases studied in 38 cases, cystic artery arose from the right hepatic artery, in one it arose from the common hepatic artery and in two specimens it arose from the proper hepatic artery. In one an accessory cystic artery from the common hepatic artery was also noted which travelled anterior to the common hepatic duct. In 3 cases the cystic artery was not seen inside the calot’s triangle and these arteries passed anterior to the common hepatic duct to reach the surface of the gallbladder.
Complete knowledge about these vessels is necessary for the operating surgeons to avoid unnecessary bleeding during surgical procedures and to prevent any biliary injuries post operatively.
