CONGENITAL PORTOSYSTEMIC SHUNTS IN DOGS

摘要

WHAT ARE CONGENITAL PORTOSYSTEMIC SHUNTS?Canine congenital portosystemic shunts (cPSS) are abnormal vascular communications between a tributary or branch of the portal vein and a systemic vein, allowing portal blood to bypass liver sinusoids and enter directly into the systemic venous circulation.12 Shunting of portal blood means loss of delivery of trophic factors to the liver resulting in hepatic underdevelopment, hepatic atrophy and eventual failure, and diversion of neurotoxic substances away from the liver.
