Abstract:
A 5-month-old Pembroke Welsh corgi dog was presented with a 3-month history of lethargy, inappetence, polyuria/polydipsia, and neurological signs. A diagnosis of a complex multiple intrahepatic portosystemic shunt (IHPSS) configuration was obtained by computed tomography angiogram, abdominal ultrasonography, and perioperative fluoroscopic angiography. The IHPSS was successfully attenuated by shunt embolization with a vascular plug, using a direct percutaneous hepatic approach under ultrasonographic and fluoroscopic guidance. Long-term (4 y) follow-up revealed resolution of all clinical signs. The owner elected to continue dietary modification and lactulose treatment indefinitely and the outcome was considered good. Key clinical message: Direct percutaneous hepatic approach could be considered for IHPSS attenuation in select cases where traditional transvenous approach access is considered challenging.
