Abstract:
This paper describes transvenous coil embolization of portosystemic shunt in 10 dogs. Clinical signs resolved in 4 dogs with extrahepatic shunt, and in 3 dogs with intrahepatic shunt. Two dogs of less than 3 kg died because of migration of coils to the level of the main pulmonary artery. One dog was euthanized when acute portal hypertension developed following transvenous coil embolization. Transvenous coil embolization seems to be a less invasive alternative to surgical ligation in dogs with a single intrahepatic portosystemic shunt.
