Case summary: A 10-month-old male domestic shorthair cat presented for surgical treatment of a congenital portosystemic shunt. The cat had a history of lethargy and ptyalism. Pre- and postprandial bile acids were markedly elevated. CT was performed, which revealed a single, congenital, left gastrophrenic, extrahepatic portosystemic shunt. A minimally invasive surgical approach was considered by transjugular percutaneous coil embolization of the venous shunt, which was performed without complications. Follow-up protein C and serum biochemical analyses were performed at 1, 2 and 5 months postoperatively, and were improved. The cat is alive and clinically normal 11 months postoperatively.
Relevance and novel information: This is the first report of percutaneous transvenous coil embolization for the treatment of an extrahepatic portosystemic shunt in a cat. The outcome was excellent in this patient, with no complications and complete resolution of clinical signs.
