Abstract
Congenital portacaval shunts causing signs of hepatic encephalopathy were diagnosed and surgically corrected in 2 cats. A tentative diagnosis of portacaval shunt in each case was based on history, results of physical examination, and a high venous ammonia concentration. A definitive diagnosis was established by mesenteric portography and by direct visualization of the shunt vessel during surgery.
