title: Origin of the v. portae and variability of its tributaries in laboratory animals. IV. The domestic rabbit (Oryctolagus cuniculus f. domestica, breed large chinchilla).
abstract: The authors studied the origin and variability of the tributaries of the v. portae in 30 domestic rabbits (Oryctolagus cuniculus f. domestica, breed Large Chinchilla) following the injection of blue-dyed latex into their portal bed. In 16 cases (53.3%), the v. portae was formed from four tributaries and in nine cases (30.0%) from three. The only constant contributory veins were the v. mesenterica cranialis and v. lienalis; the other tributaries (the v. gastroduodenalis. v. pancreaticoduodenalis cranialis and v. gastroepiploica dextra, etc) were variable. In 26 cases (86.7%), the v. gastrica sinistra joined the v. lienalis. In six cases (20.0%) it was an independent tributary of the v. portae and in six cases (20.0%) it was doubled. A v. cardiaca was found in all 30 rabbits (100%). In 23 (76.7%) it was a tributary of the v. gastrica sinistra and in seven (23.3%) it was an independent tributary of the v. portae. A v. pylorica was also present in all 30 cases (100%). In 16 (53.3%) it united with the v. gastroepiploica dextra, in eight (26.7%) it joined the v. gastroduodenalis and in four (13.3%) it was a tributary of the v. pancreaticoduodenalis cranialis. A v. pancreaticoduodenalis cranialis was found in 29 cases (96.7%). In 17 cases (56.7%) it was one of the initial tributaries of the v. gastroduodenalis and in eight (26.7%) it participated in formation of the v. portae as an independent trunk. In two cases (6.7%) it was doubled, the more cranial vein being a tributary of the v. portae.(ABSTRACT TRUNCATED AT 250 WORDS)
