Velamentous cord insertion Velamentous cord insertion Velamentous cord insertion is an abnormal condition during pregnancy. Normally, the umbilical cord inserts into the middle of the placenta as it develops. In velamentous cord insertion, the umbilical cord inserts into the fetal membranes (choriamniotic membranes), then travels within the membranes to the placenta (between the amnion and the chorion). The exposed vessels are not protected by Wharton's jelly and hence are vulnerable to rupture. Rupture is especially likely if the vessels are near the cervix, in which case they may rupture in early labor, likely resulting in a stillbirth. This is a serious condition called
Lateral umbilical fold due to the placement of the opening of the deep inguinal ring in the space lateral to the lateral umbilical fold, which allows the passage of the ductus deferens, testicular artery, and other components of the spermatic cord in men, or the round ligament of the uterus in women. Lateral umbilical fold The lateral umbilical fold overlies the inferior epigastric artery (a branch of the external iliac artery) and its accompanying veins. Unlike the median and medial umbilical folds, the contents of the lateral umbilical fold remain functional after birth. It originates just medial to the deep inguinal ring to
