Abstract

The porto-systemic bypass (DPS) or porto-systemic shunt is the most common hepatic circulatory failure in dogs. This pathology is an abnormal connection between the portal and systemic circulation that diverts blood flow from the liver to varying degrees. Thus, toxic and hepatotróficas important arising from the pancreas and intestines are absorbed and sent directly to circulation, bypassing the liver. This decrease in blood flow will result in subsequent atrophy and dysfunction of liver, steadily decreasing hepatic metabolism of the intestinal toxins that accumulate in the blood. The definitive treatment is surgical, by correcting the anomaly. If surgery is not performed, the long-term clinical treatment can be effective for up to two years.
