The right hepatic artery is an end artery and contributes sole arterial supply to right lobe of the liver. Misinterpretation of normal anatomy and anatomical variations of the right hepatic artery contribute to the major intraoperative mishaps and complications in hepatobiliary surgery. The frequency of inadvertent or iatrogenic hepatobiliary vascular injury rises with the event of an aberrant anatomy. This descriptive study was carried out to document the normal anatomy and different variations of right hepatic artery to contribute to existing knowledge of right hepatic artery to improve surgical safety. This study conducted on 60 cadavers revealed aberrant replaced right hepatic artery in 18.3% and aberrant accessory right hepatic artery in 3.4%. Considering the course, the right hepatic artery ran outside Calot’s triangle in 5% of cases and caterpillar hump right hepatic artery was seen in 13.3% of cases. The right hepatic artery (normal and aberrant) crossed anteriorly to the common hepatic duct in 8.3% and posteriorly to it in 71.6%. It has posterior relations with the common bile duct in 16.7% while in 3.4% it did not cross the common hepatic duct or common bile duct. The knowledge of such anomalies is important since their awareness will decrease morbidity and help to keep away from a number of surgical complications.

The right hepatic artery is an end artery and contributes sole arterial supply to right lobe of the liver . It also supplies the gall bladder, cystic duct, common hepatic duct and upper and middle part of common bile duct. Normal hepatic arterial anatomy occurs in approximately in 80% of cases, for the remaining 20% multiple variations have been described. Misinterpretation of anatomical variations of the right hepatic artery contribute to the major intraoperative mishaps and complications in hepatobiliary surgery. Materials and Methods: This descriptive study conducted on 50 cadavers in Department of Anatomy,Govt Medical College, Kozhikode to document the normal anatomy and different variations of right hepatic artery regarding its origin and relation with the common hepatic duct. Results : Right hepatic artery had its origin from proper hepatic artery in 47 (94%) cases, in one case the artery came from common hepatic artery, aberrant origin of right hepatic artery was seen in 4% cases, one case from celiac trunk directly and the other from superior mesenteric artery. Relation with common hepatic duct : In 46 cases (92%) the artery (normal and aberrant) passes posterior to common hepatic duct. In 6%, the artery was related anterior to common hepatic duct. In one case the artery was medial to the common hepatic duct. Conclusions : This study highlights the importance of knowledge of such anomalies since their awareness will decrease morbidity and help to keep away from a number of surgical complications.

Abstract Background and aims : The right hepatic artery occasionally forms a sinuous tortuousity called as caterpillar hump or Moynihan's hump, which occupies the major portion of Calot's triangle. Due to this variation, inadvertent injury to right hepatic artery may occur during surgical procedures. The aim of the study is to find out the incidence of Caterpillar hump of right hepatic artery in cadavers and to correlate with surgical significance. Materials and methods : Sixty cadavers allotted for the purpose of teaching undergraduate students from the period of 2006 to 2011 were used for this study. Branches of coeliac trunk were traced and right hepatic artery was observed for the presence of caterpillar hump. Results : Caterpillar hump was noted in three out of 60 cadavers (5%). Out of three specimens with caterpillar hump, right hepatic artery passed posterior to common hepatic duct in two specimens and anterior to it in one specimen. The presence of dual loops of right hepatic artery was noted in two specimens and single loop was observed in one specimen. Conclusion: The presence of this variant course of right hepatic artery may lead to the formation of short cystic artery. Thereby, right hepatic artery can be mistaken for cystic artery and may be injured during surgical procedures. The knowledge of caterpillar hump of right hepatic artery is essential for the surgeons to avoid the risk of ischemic necrosis of right lobe of liver.

Aberrant Hepatic Artery

The vascular anatomy of the liver is subjected to many variations. Aberrant hepatic artery is not an uncommon finding during visceral surgery; however, topographic variations are less reported in the literature. Prebiliary artery crossing anteriorly to the common hepatic duct was firstly reported in 1984. We present here a case of a 52-year-old lady who presented with obstructive jaundice and right upper quadrant pain. Paraclinical investigations were consistent with intrahepatic stones and a benign stricture on the CBD. During surgery, a prebiliary right hepatic artery compressing the CHD was noted. The liver pedicle was dissected and a hepaticojejunostomy was performed that resulted in a good outcome after 24 months of followup.

Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency. Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior segmental branches, the way they form the right hepatic duct, and the main variations of their drainage pattern. Results. The anatomy of the right hepatic duct was typical in 65.75% of samples. Ectopic drainage of the right anterior duct into the common hepatic duct was found in 15.07% and triple confluence in 9.59%. Ectopic drainage of the right posterior duct into the common hepatic duct was discovered in 2.74% and ectopic drainage of the right posterior duct into the left hepatic duct in 4.11%. Ectopic drainage of the right anterior duct into the left hepatic ductal system and ectopic drainage of the right posterior duct into the cystic duct was found in 1.37%. Conclusion. The branching pattern of the right hepatic duct was atypical in 34.25% of cases. Thus, knowledge of the anatomical variations of the extrahepatic bile ducts is important in many surgical cases.
