[Venous vascularization of the liver in the human fetus].

The authors have studied the veinous pattern of 30 livers of human foetuses from 190 to 390 mm V.C. The injection-corrosion method was used. The portal and sus-hepatic distribution is more frequently modal than for the adult. The portal anomalies touch more frequently the left branches: drainage of the right para-medial area by the left para-medial vein, agenesis or atrophy of the left segmentary branches. The right branch breaks up into several branches in 51% of the cases. The sus-hepatic anomalies are distinguished by the plurality of the veins. The right middle and inferior veins are present in 70% of the cases. Exceptionally large peripheral anastomoses between portal and sus-hepatic systems are observed.
