Clinical characteristics of, prognostic factors for, and long-term outcome of dogs with multiple acquired portosystemic shunts: 72 cases (2000-2018).

Objective: To identify clinical characteristics of, prognostic factors for, and long-term outcome of dogs with multiple acquired portosystemic shunts (MAPSSs) and determine whether survival time was associated with previous portosystemic shunt attenuation.

Animals: 72 client-owned dogs with MAPSSs.

Procedures: Medical records of dogs in which MAPSSs had been diagnosed between January 2000 and August 2018 were reviewed for signalment, historic and diagnostic findings, management methods, and outcome.
