Figure 1From: Distribution of extrahepatic congenital portosystemic shunt morphology in predisposed dog breedsLocalization and gender distribution of extrahepatic portosystemic shunts in 135 purebred dogs. The dogs were seen in the period from 2001–2010. The shunt diagnosis was based on a high fasting venous ammonia level or abnormal ammonia tolerance test and the visualisation by ultrasonography or computed tomography. In most cases the diagnosis was independently visually confirmed during surgery.Back to article page
