“…In this study we found a case with an accessory right hepatic artery arising directly from the celiac trunk. In the present study, the origin of accessory hepatic artery is seen from CT (10%; 1 out of 10 cases), whereas Yamashita et al 33 has reported the variation in 0.24% cases (16 out of 5696 cases). This could be because of less number of cases in this study.…”

Celiac Trunk (CT) or celiac artery is the major ventral branch of the abdominal aorta supplying the supracolic compartment of the abdomen. Anatomical variations in the branching pattern of Celiac axis have been reported earlier (1,2,3) and are of great surgical importance. Lot of variations was found in the branching pattern of CT during routine cadaveric dissection in the department of Anatomy, North Delhi Municipal Corporation Medical College and Hindu Rao Hospital, Delhi. Hence, a study was taken up to dissect and examine 10 cadavers available in the department. The CT was studied for accessory branches and their pattern of emergence. Length of each branch was measured and appropriate photographs were taken. In this study trifurcation of celiac trunk is seen in (70%; 7 out of 10 cases), bifurcation in (10%; 1 out of 10 cases), pentafurcation in (10%; 1 out of 10 cases) and heptafurcation also in (10%; 1 out of 10 cases). Tetrafurcating, Hexafurcating and absent celiac trunk was not observed in our study. Rare variations in the CT branching are found in higher proportion than previously reported.

Rare combined variations of renal, suprarenal, phrenic and accessory hepatic arteries

et al. 2018

Knowledge of the morphological variations within the abdominal cavity is significant for all medical practitioners planning surgery. This report presents the rare origin of a common trunk for the right inferior phrenic artery, and superior and inferior suprarenal artery from the right renal artery. An accessory hepatic artery was found, which served as a branch of the right inferior phrenic artery. The diameter of the common trunk was 3.95 mm, and the diameters of the inferior and superior suprarenal arteries were 1.84 and 1.36 mm, respectively. The diameter of the right inferior phrenic artery was 2.55 mm. Both the embryological background and the potential clinical significance of this morphological variation are discussed. Knowledge of this common trunk and the occurrence of the accessory right hepatic artery may be of significance in diagnostic and surgical procedures.

“…Although there is only one report of such an anomaly available in the literature [2], we can assume, however, that the common hepatic artery or the vessel which it replaces, such as the right hepatic artery in our case, shows the tendency to occupy the retroportal position in the portal triad. Bearing in mind that the cystic artery branches out from the right hepatic artery even if the last one takes an aberrant course and begins from the superior mesenteric or gastroduodenal arteries, such variation represents a high risk for surgery on hepatobiliary tract [3,11,17]. The co-existence of the retroportal right hepatic artery with the aberrant accessory cystic duct makes the presented case even more unfavorable for surgery, as a failure to recognize the accessory cystic duct may lead to bile leakage, biliary peritonitis, or the formation of a fistula [1,14].…”

“…The conventional anatomy of the celiac trunk and its branches is found in 60 to 90% of cases, depending on the study [10,12,17]. The possible variations of origin of the common hepatic artery from the splenic (4.5%), mesenteric (2.5%), celio-mesenteric (1%), and spleno-mesenteric (0.7%) arteries were summarized in Michel's classification of types of hepatic blood supply [10].…”

“…Abnormal origin of the gastroduodenal artery is typically associated with the presence of accessory aberrant hepatic arteries and with the reposition of the common hepatic artery that significantly alters the contents of porta hepatis [11]. Such anomalous hepatic blood supply is a challenge for surgeons performing open cholecystectomies and liver transplantations, not to mention specialists employing the laparoscopic and transvascular non-invasive techniques [2,3,17]. The coexistence of atypical hepatic vascular patterns with biliary duct anomaly compromises outcomes of the surgical procedures on the gallbladder and liver even more [14].…”
