Abstract:
Peculiarities of structure and development of arterial vessels of common bile duct (CBD) has been researched
on 68 series of hystologic sections of embryos and 62 corpses of human fetuses and newborns. It has been established
that since 7th week of prenatal period the origins of arterial supply of CBD are anastomotic branches of posterior pancreato-duodenal
arcade and anterior superior pancreato-duodenal a. partially. Primordium of definitive structure of arterial
vessels of intramural part of CBD is identified as intermuscular and subepithelial vascular plexuses, which situated around
the basis of major duodenal papilla in fetuses 82,0-170,0 mm in parietal-coccygeal length.
