Summary
Congenital portosystemic encephalopathy in dogs is often seen in Australian cattledogs. Treatment success varied, with medical management alleviating signs in most dogs.
Area of Science:
- Veterinary Medicine
- Canine Internal Medicine
- Surgical Pathology
Background:
- Congenital portosystemic encephalopathy (CPS) is a serious condition in dogs.
- This review examines 21 canine cases to understand breed predispositions and clinical findings.
Purpose of the Study:
- To review cases of congenital portosystemic encephalopathy in dogs.
- To identify common breeds, clinical pathology findings, and radiological signs.
- To evaluate the outcomes of surgical and medical management.
Main Methods:
- Retrospective case review of 21 dogs diagnosed with congenital portosystemic encephalopathy.
- Analysis of clinical signs, clinical pathology results, and radiological findings.
- Evaluation of surgical ligation and medical management outcomes.
Main Results:
- Australian cattledogs were most commonly affected (8 cases).
- Extra-hepatic shunts were prevalent in small breeds, intra-hepatic in larger breeds.
- Common findings included abnormal ammonia tolerance, elevated liver enzymes, low serum protein, and small livers.
Conclusions:
- Congenital portosystemic encephalopathy has breed predispositions and characteristic clinical findings.
- Surgical intervention for extra-hepatic shunts had limited success in this cohort.
- Medical management provided clinical sign alleviation in a majority of affected dogs.
