Abstract:
We examined 27 resin casts of foetal liver veins and found three types of connection between portal vein and portal sinus. The most frequent connection was endo-lateral (66.7%), when the end of the portal vein joins with the lateral wall of the portal sinus. The next type was latero-lateral (14.8%). In this type, the lateral walls of the portal sinus and the portal vein join together. The last type was latero-lateral through short vessel (18.5%), which resembles the previous one, but there is short vessel between the lateral walls of the portal vein and sinus.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Hepatic Portal System
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...
