THE CADAVERIC STUDY OF INCIDENCES OF ACCESSORY CYSTIC ARTERY AND ITS CLINICAL SIGNIFICANCE

Abstract

The cystic artery is the main source of blood supply to the gallbladder and cystic duct. The cystic artery usually arises from the right hepatic artery. It divides into superficial and deep branches at the neck of the gall bladder. The superficial branch ramifies on the inferior aspect of the gallbladder body, the deep branch on the superior aspect. The cystic artery gives rise to multiple fine branches which supply the common and lobar hepatic ducts and upper part of the common bile duct. The present study was conducted to find out the prevalence of double cystic arteries. The recognition of this variation is important to avoid intra-operative bleeding during Cholecystectomy. The study was carried out on 100 adult human cadavers in different medical colleges of the Gujarat region. The variations of a present number of the cystic artery were observed if found then documented and photographed.Out of 100 specimens, 12(12%) specimens present double cystic arteries. Out of 12 specimens in 10 specimens the cystic artery arises from the right hepatic artery and in 2 specimens cystic artery arises from a segmental branch of the right hepatic artery. This study is emphasizing the importance of a thorough knowledge of anatomy and recognition of variations of the cystic artery are essential prerequisites for safe and uneventful laparoscopic Cholecystectomy and can reduce uncontrolled intra-operative haemorrhage and extrahepatic biliary injury. The recognition of anatomical variations is important for avoiding intra-operative haemorrhage during Cholecystectomy.
