Cord insertion abnormalities refer to irregularities in how the umbilical cord attaches to the placenta. Normally, the cord inserts centrally, but in some cases, it may insert at the edge (marginal insertion) or even outside the placenta (battledore or marginal insertion). These variations can affect blood flow and nutrient transfer between the mother and fetus. Such abnormalities can lead to complications during pregnancy and delivery, including fetal growth restriction or preterm birth. Monitoring through ultrasound is essential to assess the health of the fetus and the effectiveness of the cord's function, ensuring appropriate medical care is provided.
