A liver shunt is a blood vessel that carries blood around the liver instead of through it. 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.
The purpose of these shunts is to bypass certain body parts â in particular, the lungs and liver â that are not fully developed while the fetus is still in the womb. The shunt that bypass the lungs is called the foramen ovale. It moves blood from the right atrium of the heart to the left atrium.hen the blood enters the right atrium, most of it flows through the foramen ovale into the left atrium. Blood then passes into the left ventricle (lower chamber of the heart) and then to the aorta (the large artery coming from the heart).
