Imaging of Congenital Portosystemic Shunts
T he normal portal vascular system transports venous blood from the stomach, intestines, spleen, and pancreas to the hepatic sinusoids and ultimately the hepatic veins and caudal vena cava. Portosystemic shunting (PSS) occurs when abnormal vascular connections occur between the portal and systemic venous systems, bypassing the liver. This can be acquired secondary to portal hypertension arising...

متن کاملPortosystemic shunts in dogs and cats: imaging portosystemic shunts in small animals – ultrasonography, nuclear scintigraphy, computed tomography, magnetic resonance imaging
Because of the non-specificity of the clinical signs and laboratory findings, imaging techniques such as portography, ultrasonography (US), nuclear scintigraphy, computed tomography (CT), or magnetic resonance imaging (MRI) are required to provide a definitive diagnosis of portosystemic shunts (PSSs). Nuclear scintigraphy is the gold standard for detecting PSSs, but it is not useful in distingu...
متن کاملPortosystemic shunts in dogs and cats: laboratory diagnosis of congenital portosystemic shunts
The most frequent laboratory abnormalities in patients with congenital portosystemic shunts (CPSS) are microcytosis, hypoglycemia, hypoalbuminemia, hypoproteinemia, increased liver enzyme activities, decreased blood urea nitrogen (BUN) and urate crystalluria. The microcytosis is probably due to impaired iron transport. Hypoglycemia, hypoalbuminemia, hypoproteinemia and decreased BUN are partly ...
متن کاملPortosystemic shunts in dogs and cats: definition, epidemiology and clinical signs of congenital portosystemic shunts
Congenital portosystemic shunts (CPSS) are hepatic vascular anomalies which can affect any breed of dog or cat. Extrahepatic CPSS are most commonly observed in cats and small dogs, whereas intrahepatic CPSS are more likely to affect large breed dogs. A hereditary basis has been observed in some dog breeds. Affected animals are usually presented at young age with a variety of neurological, gastr...
