Veiled insertion is a problem in the connection of the umbilical cord to the placenta, reducing the baby's nutrition during pregnancy, which can cause sequelae such as growth restriction in the baby, requiring more vigilance through ultrasounds to monitor its development.
In this case, the umbilical cord is implanted in the membranes and the umbilical vessels travel a path of variable length before being inserted into the placental disk, as is normally the case. The consequence of this will be a decrease in circulation to the fetus.
Veiled insertion has clinical significance: it is more related to maternal diabetes, smoking, advanced maternal age, congenital malformations, fetal growth restriction and stillbirth.
Veiled insertion can be considered an obstetric emergency if the blood vessels are twisted or the membranes rupture, causing major bleeding, especially at the end of pregnancy. In these more severe cases, a cesarean should be performed as soon as possible, as the baby is at risk of life.
Diagnosis of veiled insertion
The diagnosis of velorous insertion is made by ultrasound in the prenatal period, usually from the second trimester.
Treatment for velvet insertion
Treatment for veiled insertion depends on the baby's growth and the presence or absence of bleeding.
If there are no major bleeds, it is a sign that the pregnancy has a good chance of successfully ending with a cesarean section. In such cases, only more careful medical monitoring through periodic ultrasounds in the third trimester is enough to verify that the baby is growing and eating properly and satisfactorily.
However, in cases of twin pregnancies and placenta previa, there is a greater possibility of complications. Intense bleeding may occur mainly at the end of pregnancy due to rupture of the membranes, and the immediate removal of the baby through an emergency cesarean section is indicated.
