The bile duct supply branches, from the proper hepatic artery (the trunk type) and from the gastroduodenal artery (the branch type), showed an anastomotic network [Figure 1]d.
In the lower part, the branches from the gastroduodenal artery and the lower branches of the proper hepatic artery traveled upward along the surface of the extrahepatic bile duct.
However, there are quite a few reports on the bile duct supply branch from gastroduodenal artery.
Occasionally (3 pieces studied), the gastroduodenal artery can also give rise to collateral artery that distributes to the lesser curvature of the stomach and in the caudate, right lateral and right medial lobes.
In the second type of the bifurcation of the hepatic artery, in which it emits collaterals which supply the caudate, right lateral, right medial lobes and the gall bladder (cystic artery), the hepatic artery branches off in the gastroduodenal artery and in the left branch.
The gastroduodenal artery can suppy branches for the caudate, right lateral, right medial, quadrate lobes, gall bladder (cystic artery) and branches for the lesser stomach curvature.
It showed GB posterior wall defect suggesting perforation, changes of chronic pancreatitis and large thrombosed aneurysm of gastroduodenal artery with mass effect, metallic coil, gross ascites and bilateral pleural effusion.
EPIDEMIOLOGY: Gastroduodenal artery (GDA) aneurysms are rare but a potentially fatal condition if rupture occurs.
The pathophysiologic changes that underlay the development of true gastroduodenal artery aneurysms comprise mainly atherosclerosis of the celiac artery with subsequent stenosis but also rarely congenital absence of the celiac axis.
