In some animals a liver shunt is a birth defect (congenital portosystemic shunt).In others, multiple small shunts (acquired portosystemic shunts) form because of severe liver disease such as cirrhosis. portogram is an x-ray of the blood vessels to the liver. Because blood vessels are not easily seen on regular x-rays, a contrast material (a liquid that looks white on x-rays) must be injected into a blood vessel in the abdomen.
