Velamentous cord insertion is a complication of pregnancy where the umbilical cord is inserted in the fetal membranes. It is a major cause of antepartum hemorrhage that leads to loss of fetal blood and associated with high perinatal mortality.
Umbilical cord compression can result from, for example, entanglement of the cord, [16] a knot in the cord, [16] or a nuchal cord, [16] (which is the wrapping of the umbilical cord around the fetal neck) [17] but these conditions do not always cause obstruction of fetal circulation.

Vasa previa is seen more commonly with velamentous insertion of the umbilical cord, accessory placental lobes (succenturiate or bilobate placenta ), multiple gestation, and in vitro fertilisation pregnancy. In IVF pregnancies, incidence as high as one in 300 has been reported [citation needed].
The findings suggest deferred clamping of the umbilical cord likely reduced the risk of death in premature babies by a third, compared to immediate clamping.
The amnion is the innermost layer and, therefore, contacts the amniotic fluid, the fetus and the umbilical cord. [5] The internal pressure of the amniotic fluid causes the amnion to be passively attached to the chorion. [4] The chorion functions to separate the amnion from the maternal decidua and uterus. [4]
The newborn, with normal APGAR scores and umbilical cord arterial pH levels, was admitted to the neonatal intensive care unit. Upon examining the placenta after delivery, it was noted that the placenta demonstrated the appearance of a circumvallate placenta, and also showed evidence of abnormal umbilical cord insertion into the placenta.
Prior to the onset of the amniocentesis, the pregnant patient will undergo ultrasound evaluation to assess fetal viability and position, gestational age, amniotic fluid volume, maximum vertical pocket, umbilical cord insertion site, and any obvious fetal deformities.
While umbilical cord keepsakes are going viral on social platforms like TikTok, the preservation practice is not new. Carmen Calvo, 43, of San Antonio, Texas, has been creating keepsakes from ...
