🔍 Key Findings
Study population: 21 dogs with portocaval extrahepatic portosystemic shunts (EHPSS)
Surgical approach: 67% (14/21) underwent ameroid constrictor placement
Perioperative complications: 4 dogs (19%), including seizures (n = 2), vomiting, and abdominal effusion
Perioperative mortality: 1 dog (5%)
Postoperative clinical outcome:
- Good to excellent outcome: 81% (17/21)
- Median follow-up: 6 months (range 3–43)
Persistence of shunting (CT or US): 56% (9/16 evaluated)
Dogs with persistent shunting: 67% still had good to excellent clinical outcome
Congenital portocaval shunts may have more favorable outcomes than previously reported
