What is the name of an abnormal blood vessel causing unusual blood flow around the liver?

A portosystemic shunt refers to an abnormal blood vessel that diverts blood away from the normal liver circulation. Normally, blood from the intestines flows through the portal vein to the liver, where it is processed. In the case of a portosystemic shunt, blood bypasses the liver, which can result in several metabolic issues, including the accumulation of toxins that would normally be filtered out by the liver.

This abnormal connection can occur either congenitally (present at birth) or develop as a complication of liver disease. The implications of a portosystemic shunt are significant because it can lead to hepatic encephalopathy as the liver is unable to metabolize toxins effectively. Understanding this condition is crucial for recognizing how it affects overall animal health and how it can be addressed through medical or surgical intervention.
