Abstract
The fetal umbilical vein in the ligamentum teres can be reopened to provide a 10 cm long vein, as wide as the left portal vein or the central splenic vein, that gives access to the left portal vein in the umbilical fissure of the liver. By cutting the ligamentum teres, this potential autologous venous graft is lost and, therefore, the ligamentum teres should never be sacrificed without reason. The umbilical side of the reopened umbilical vein can be anastomosed with the splenic vein to form a portal vein bypassing conduit that enters the liver in the umbilical fissure and take over function of the portal vein. Radical block resection of the area consisting of the hepatic duct confluence, classic right hepatic lobe and complete hepatoduodenal ligament, preceded by construction of a complete separate afferent blood supply of the classic left hepatic lobe, is possible both anatomically and technically. There is no indication denying the supposition that the result of such a procedure is functionally analogous to standard extended right lobectomy with bilioenteric reconstruction.
