OBJECTIVE To determine the annual and overall proportion of diagnoses of congenital portosystemic shunts (CPSS) in dogs and identify breeds at increased risk for CPSS. DESIGN Retrospective study. ANIMALS 2,400 dogs with CPSS from veterinary teaching hospitals that reported to the Veterinary Medical Database (VMDB) from January 1, 1980 to February 28, 2002. PROCEDURE The proportion of diagnoses of CPSS was calculated for all dogs and each breed recorded in the VMDB annually and for the 22… Expand

TLDR
Breed has a significant influence on shunt anatomy in dogs and cats and dogs that were not predisposed to portosystemic shunts were significantly more likely to have unusual or inoperable shunts than dogs frompredisposed breeds. Expand
Diagnosis of congenital portosystemic shunt in miniature schnauzers 7 years of age or older (1997-2006).
TLDR
Congenital PSS should be considered in mature dogs, particularly miniature schnauzers, that are presented with signs potentially consistent with hepatic encephalopathy when compared to all other breeds of dogs. Expand
Epidemiologic factors associated with the anatomic location of intrahepatic portosystemic shunts in dogs.
TLDR
Although country of origin, breed, and sex had significant associations with anatomic location of IHPSS, signalment does not appear to be a strong predictor of shunt location when used alone. Expand
investigating congenital portosystemic shunts in Deerhounds
A retrospective study to determine the prevalence of congenital portosystemic shunts (cPSS) in Deerhounds, focussing on the UK and the USA. Worldwide, the prevalence of shunts was found to be 0.8%Expand
Distribution of extrahepatic congenital portosystemic shunt morphology in predisposed dog breeds
TLDR
The remarkable similarity of phenotypic variation in many dog breeds may indicate common underlying genes responsible for EHPSS across breeds. Expand
More answers needed on congenital portosystemic shunts in dogs and cats
TLDR
An appreciation of the anatomical and pathological features of CPSS at gross and microscopic levels is important for diagnostic investigation and in guiding approaches to treatment. Expand
Risk factors for urolithiasis in dogs with congenital extrahepatic portosystemic shunts: 95 cases (1999-2013).
TLDR
In dogs with EHPSS, shunt morphology was not associated with increased odds of urolithiasis at the initial evaluation, but the odds were significantly increased for male dogs, older dogs, and dogs that received previous medical treatment. Expand
Analysis of the relationship of extrahepatic portosystemic shunt morphology with clinical variables in dogs: 53 cases (2009-2012).
OBJECTIVE To investigate differences in clinical variables among dogs with extrahepatic portosystemic shunts (EHPSSs) of various morphologies. DESIGN Retrospective case series. ANIMALS 53 dogsExpand
Long-Term Outcome After Surgical Ligation for Treatment of Congenital Portosystemic Shunts in Dogs
TLDR
Shunt attenuation by ligation is an effective technique to improve the quality of life of dogs with CPSS and the concept of the PSS scoring system developed shows a promising additional method for diagnosing clinical PSS. Expand
Portosystemic shunts in dogs and cats: definition, epidemiology and clinical signs of congenital portosystemic shunts
TLDR
Congenital portosystemic shunts (CPSS) are hepatic vascular anomalies which can affect any breed of dog or cat and are usually presented at young age with a variety of neurological, gastrointestinal, urinary or other signs. Expand

Medical management of congenital portosystemic shunts in 27 dogs--a retrospective study.
TLDR
It was demonstrated that a significant proportion of dogs with portosystemic shunts managed medically have a good prognosis, with two prognostic indicators identified, age at initial signs and blood urea concentration on presentation, both correlating with survival time. Expand
Canine congenital portosystemic encephalopathy.
TLDR
The case records of 21 dogs with congenital portosystemic encephalopathy are reviewed and it is revealed that all the dogs had a small liver and the kidneys were enlarged in 5 of 10 dogs in which kidney size could be estimated. Expand
Prediction of inherited portosystemic shunts in Irish Wolfhounds on the basis of pedigree analysis.
OBJECTIVE To test validity of prediction for inherited portosystemic shunts (PSS) in Irish Wolfhounds, using nonselective clinical findings and a computerized database containing 5-generationExpand
Increasing incidence of hereditary intrahepatic portosystemic shunts in Irish wolfhounds in The Netherlands (1984 to 1992)
TLDR
The overrepresentation of portosystemic shunts in Irish wolfhounds, the increasing rate of incidence of the shunts, and the familial distribution of the animals with the condition are evidence for a hereditary basis for the disorder in this population. Expand
Gauged attenuation of congenital portosystemic shunts: Results in 160 dogs and 15 cats
TLDR
Portosystemic shunts were ligated over a gauged stainless steel rod in 160 dogs and 15 cats, using a midline celiotomy, with a significant higher probability of recurrence of HE in cats than in dogs. Expand
Intrahepatic and extrahepatic portal venous anomalies in dogs: 52 cases (1982-1992).
TLDR
Medical records of 52 dogs born with portal venous anomalies were reviewed and separated into 2 groups, based on anatomic location of the shunt (intrahepatic vs extrahePatic), to compare the groups with respect to presurgical clinicopathologic data and to identify predictors of early postoperative mortality. Expand
Intrahepatic and extrahepatic portal venous anomalies in dogs: 52 cases (1982-1992).
TLDR
Medical records of 52 dogs born with portal venous anomalies were reviewed and separated into 2 groups, based on anatomic location of the shunt (intrahepatic vs extrahePatic) to compare the groups with respect to presurgical clinicopathologic data, as well as to compare postoperative mortality. Expand
Congenital portosystemic shunts in Maltese and Australian cattle dogs.
TLDR
Fasting blood ammonia concentration was elevated in 20 of 22 dogs tested, providing a minimally invasive and effective means of diagnosis, and clinical syndromes resulting from anomalous portosystemic communications were indistinguishable in the 2 breeds. Expand
Surgical treatment of intrahepatic portosystemic shunts in 45 dogs
TLDR
In the dogs with a PDV, the shunt vessel could be most easily manipulated at a posthepatic site, whereas in those with central and right divisional shunts the manipulation could be more easily made intrahepatically but sometimes involved demanding intravascular surgical techniques. Expand
Surgical treatment of intrahepatic portosystemic shunts in six cats
TLDR
All the cats recovered from the surgical procedure, but one developed neurological signs shortly after the operation and died from respiratory failure, and one cat required long-term medication to control its continued clinical signs. Expand
