In the fetus, oxygenated blood flows from the placenta through the umbilical vein and into fetal circulation. Patency and utility for vascular access remains until about one week after birth. This vein is frequently utilized for vascular access in the neonate when necessary for emergency resuscitation, transfusion or central venous access.
In the adult, the umbilical vein undergoes degeneration and forms the ligamentum teres hepatis which extends from the free edge of the falciform ligament of the liver to the umbilicus. In portal hypertension, collateral pathways begin to form. One of which is by recannulization of the umbilical vein as seen in our patient.
