Conjoined right hepatic artery from branches of the common hepatic and gastroduodenal arteries: a rare anatomic variant

Anatomical variations of the celiac trunk are numerous. Variants of the hepatic artery are important to consider especially in the bilio-pancreatic procedures. Unusual arterial anatomy increases the risk of postoperative specific complications. We report a case of a rare anatomic variant of the celiac trunk that gives rise to a left and right hepatic artery separately. It is an exceptional variant found in a patient with a pancreatic head tumor and candidate for duodenopancreatectomy. Key words: celiac trunk, right hepatic artery, anatomic variant.

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

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.
