Morphological Investigation of the Veins and Bile Vessels of Rabbit Liver

Abstract

The focus was to investigate the anatomical specifics of v. portae, vv. hepaticae and ductus choledochus by corrosion. We investigated 10 sexually mature, clinically healthy New Zealand White rabbits, 8 months old, weighing 2.8 kg to 3.2 kg. To determine the veins and bile vessels, a cold-curing acrylic-based plastic (Duracryl +) was used. The main portal vessel was an intraorganic continuation of v. portae, after its branching into caudate lobe. The main portal vein was divided into v. portae dextra and v. portae sinistra, when entering lobus hepatis dexter and lobus hepatis sinister. V. portae sinistra caudalis was a branch of v. portae sinistra. The venous drainage of the rabbit liver in was carried out by v. hepatica sinistra caudalis, v. hepatica sinistra, v. hepatica dextra, v. hepatica media and venous vessel in lobus caudatus. V. hepatica sinistra and v. hepatica media had a common origin and took blood from lobus hepatis sinister medialis. V. hepatica dextra drained lobus hepatis dexter. V. hepatica sinistra caudalis was a direct tributary of the caudal vena cava. Ductus hepaticus communis was well developed and collected the bile from the main bile duct. Ductus hepaticus dexter drained lobus hepatis dexter and evacuated the bile into the main bile duct. Ductus hepaticus sinister caudalis flowed directly into ductus hepaticus communis. Ductus hepaticus sinister passed into the main bile duct.
