Hepatic encephalopathy in two aged dogs secondary to a presumed congenital portal-azygous shunt

Hepatic encephalopathy in two aged dogs secondary to a presumed congenital portal-azygous shunt

Journal of the American Animal Hospital Association 25(2): 129-137

Two dogs, aged 10 and 7 years, had clinical signs of hepatic encephalopathy of one and four months' duration, respectively. A single portal-azygous shunt was identified by angiography in each dog. The shunt was considered congenital in origin because of its anatomical configuration and absence of severe histological hepatic lesions. Shunt ligation resulted in dramatic clinical improvement in both dogs; however, biochemical evaluation of hepatic function did not improve.
