Portosystemic shunt (PSS) is a relatively common phenomenon in dogs. PSS may be either intrahepatic (IHPSS) or extraheptic (EHPSS), congenital or acquired. The most commonly identified shunts are of congenital origin and consist of single, large intrahepatic or extrahepatic shunts. Since the discovery of the condition, PSS has been treated by medical or surgical methods, or a combination of both. Surgical techniques for partial attenuation of EHPSS and IHPSS include silk suture attenuation, ameroid constrictor placement, cellophane banding, and hydraulic occluders.
This article describes the diagnostic process and the treatment of a case of IHPSS in a 7-month-old male entire Bull Mastiff, and provides an in depth discussion regarding clinical and diagnostic features, surgical treatment, complications, follow-up and prognostic factors.
