Long-term outcome and quality of life of dogs that developed neurologic signs after surgical treatment of a congenital portosystemic shunt: 50 cases (2005-2020).

Objective: To determine survival time and quality of life of dogs that developed postattenuation neurologic signs (PANS) after surgical treatment of a single congenital portosystemic shunt and survived at least 30 days and identify whether neurologic signs present at the time of discharge would resolve or reoccur.

Animals: 50 client-owned dogs.

Procedures: Medical records were retrospectively reviewed, and follow-up data relating to neurologic signs and seizure activity were obtained.
