The Hepatic, Cystic and Retroduodenal Arteries and Their Relations to the Biliary Ducts

Variant anatomy of the celiac trunk –review of literature with a case report

“…Retention or disappearance of parts of this primitive arterial plexus could give rise to numerous anatomical variations in the CT 26, 34 . Anatomical variations of the coeliac arterial system were defined according to Michels' internationally recognized classification 35 . Hepatogastric trunk (SA from aorta or SMA) 5 Gastrosplenic trunk (CHA from aorta or SMA) 6…”

“…An aberrant accessory hepatic artery appears in addition to one that is normally present. An aberrant right hepatic artery usually arises from the superior mesenteric artery or the aorta 35 . The presence of replaced right or left hepatic arteries can be life saving in patients with bile duct cancer because they are further away from the bile duct and tend to be spared from the cancer, making excision of the tumour feasible 24 .…”

A Different Origin of the Right Gastro-omental Artery

“…The celiac trunk is a wide 1.25 cm long ventral branch located just below the aortic hiatus. The diameter of this trunk ranges from 8 to 40 mm (Michels, 1951). The main branches of the celiac trunk that can be usually identified are the left gastric, splenic and common hepatic arteries.…”

The Arterial Blood Supply of the Extrahepatic Biliary Tract - Surgical Aspects

“…The cystic artery usually arises as a single branch from the right hepatic artery (the right branch of the proper hepatic artery) within the hepatocystic triangle (4)(5)(6)(7)(8)(9)(10)(11)(12). The hepatocystic triangle is formed by the common hepatic duct (medially), the cystic duct (laterally), and the inferior margin of the right lobe of the liver (superiorly).…”

“…An accessory or double cystic artery occurs in 15-20% of cases (6,20). These arteries usually arise from the right hepatic artery within the hepatocystic triangle.…”
