[The venous vascularization of the pancreas]

The venous vascularisation of the pancreas has been studied in the West African on 157 pieces, by the method of injection-corrosion. The polymeric plastic used for this operation was Rhodopas A X 85.15. The results are quite comparable to those reported in Couppie's thesis (Lyon, 1957) on the European. The venous drainage of the head of the pancreas is secured by four arches: anterior, posterior, inferior and intra-glandular, formed by three pancreatico-duodenal veins (inferior-anterior, superior-posterior, inferior-posterior). Three other venous trunks, independant from that system, and which are not reported in the former descriptions, participate in the formation of secondary, inconstant new arches. For the body and the tail of the pancreas, the disposition in two types described by Calas was found, but with an inverted respective percentage. The lower pancreatic vein was often demonstrated with particular clearness. For the neck of the pancreas, the venous vascularisation is secured by the isthmic veins, sometimes linked in a pre-glandular arch.
