Contribution to the study of the intra and extra-hepatic biliary ductus. Systematization of the ramus principalis dexter

Abstract

The  A. has studied, the constitution of the ductus choledocus and the systematization of the ramus principalis dexter of the liver, in 30 goats (Capra hircus), 17 males and 13 females. In 26 organs the ductus choledocus is formed by the confluences of the ramus principalis dexter and ramus principalis sinister and, in other 4 livers it resulted from a triple convergence (ramus principalis dexter, ramus principalis sinister and ductus cysticus). The system of the ramus principalis dexter holds the ramus dorsalis lobi dextri, ramus medialis lobi dexter, ramus lateralis lobi dexter and ramus processi caudati; the ductus cysticus is also part of this system: the A. identifies by roots the affluents called rami intermedii lobi dextri and contribution from the lobus quadratus and lobus caudatus (pars sinistra, pons and processus caudatus).
