The vitelline arteries are the arterial counterpart to the vitelline veins. Like the veins, they play an important role in the vitelline circulation of...

extrahepatic shunts usually result from a developmental abnormality of the vitelline veins, which connect the portal vein to the caudal vena cava. Thus in...
