Morphological studies of the canine hepatic portal system
Get PDFThe aim of the study was to track hepatic veins and their inflow into the caudal hollow vein using corrosion cast, contrast helical computed tomography imaging (CT), conventional ultrasonography (US) and contrast-enhanced ultrasonography (CE-US). The corrosion cast was made on a deceased dog’s liver by injecting solidifying coloured plastic materials through the portal vein and caudal vena cava, enabling macroscopic visualisation of the portal and hepatic venous blood vessel branches up to the perilobular veins. Prior to the CT and US scans, the studied dogs were anaesthetised. The assess-ments were performed following administration of contrast media into the cephalic vein. The CT-scan images, together with the CT and CE-US images of the liver in the transversal and transversal-sagittal planes on the level from the eighth thoracic to the second lumbar vertebras, were compared. The ca-nine hepatic portal system studied using corrosion cast, contrast imaging CT and US methods showed constant pattern of blood supply anatomical disposition. These approaches were used as a model for diagnosing portosystemic shunts in subsequent studies
