Connection types between portal vein and portal sinus during foetal life.
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.
