Thick hard stricture palpable for 2 cm length involving common hepatic
duct (CHD) and confluence--Type II Bismuth tumor(fig.3 &4).Left hepatic duct was isolated, it was 9mm in diameter and1.2 cm in length.
In relation to the celiac artery, the common hepatic
artery emerged cranially in 23 animals (76.7%) and right lateral in 7 animals (23.3%), in both cases its emergency was in one way form.
It is most commonly a branch of right hepatic artery and arises in the triangle between common hepatic
duct, cystic duct and the visceral surface of the liver-the cystohepatic triangle (of Calot).
Out of twelve cases of cholangiocarcinoma, 5 cases(41.6%) had mass at the confluence of right and left hepatic ducts (Klatskin tumour), 1 case(8.3%) had mass in common hepatic
duct, 1 case (8.3%) had mass in proximal CBD and 5 cases (41.6%) had mass in distal CBD.
When the cystic artery is given off not from the RHA but from other vessels like the common hepatic
artery (2-5%) it crosses the bile duct anteriorly and may be prone to injury.
Double cystic ducts are also classified into, 'Y' type where both ducts meet and form a single duct, 'H' type where an accessory duct joins the right, left or common hepatic
duct, and the trabecular type in which the accessory duct directly enters the liver substance.
CT arises at T12/L1 level, measures 1.5-2cms and divides into left gastric artery (LGA), common hepatic
artery (CHA) and splenic arteries (SA).
It immediately divides into the left gastric, splenic and common hepatic
Our present study over a period of seven years re-affirms the fact that hepatoblastoma remains the most common hepatic
malignancy in infancy and childhood.
Since the cystic duct most likely does not drain into the CBD, we can conclude that common hepatic
duct is absent.
The Porta hepatis is centrally located in the middle third of the visceral surface; it has an "L" shape rotated ninety degrees to the left; it presents a transverse part, another anterior part, and they form a 90-degree angle of anterior medial sinus; the hepatic portal vein is divided here into right (A12.3.12.002) and left (A12.3.12.005) branches; the hepatic artery proper is divided into right (A12.3.12.030) and left (A12.3.12.035) branches; the common hepatic
duct is formed by the union of the right hepatic (A05.8.01.062) and the left hepatic (A05.8.01.065); these branches form the first vascular division; then, on the edge of this parenchymal channel, these two "primary branches" emit seven terminal secondary branches, forming seven vascular pedicles for seven portal segments.
If the acquisition parameters and timing of the contrast bolus are optimised, this resolution even allows visualisation of a tiny artery.6,7 In classical anatomical arterial pattern, coeliac axis gives rise to left gastric artery (LGA) and then bifurcates into splenic artery and common hepatic
