Thrombosis in the umbilical cord is a rare occurrence and the fact that it happened once does not mean that it occurs in subsequent pregnancies.
This is the formation of a blood clot in some part of the umbilical cord that can occur during pregnancy or childbirth, causing oxygen and nutrients not to reach the fetus in sufficient quantities, which can lead to abortion, fetal death and prematurity.
Causes of thrombosis in the umbilical cord
Umbilical thrombosis has no specific cause but may occur after cordocentesis, which is an examination in some cases guided by the obstetrician to detect diseases.
In addition, if a woman has blood clotting problems, such as thrombophilia, she is at increased risk of developing blood clots due to changes in the blood, such as antithrombin deficiency, protein C deficiency, protein S deficiency, and Leiden factor V change.
When can umbilical cord thrombosis occur?
Umbilical cord thrombosis may occur during pregnancy, early in the gestation, near the end, or even during delivery.
During delivery, umbilical cord thrombosis can be detected, and in the hospital, it may be easier to save the baby’s life and prevent other complications, such as cerebral palsy.
In umbilical cord thrombosis, a clot is occluded by the vein or artery responsible for ensuring proper development of the fetus, keeping the pregnancy healthy. Umbilical vein thrombosis is more frequent than the thrombosis of one or both arteries present in the umbilical cord, although the latter is more severe and is more associated with fetal death within the uterus.
Symptoms of umbilical cord thrombosis
Generally, thrombosis does not cause pain and is only detected when the pregnant woman does not feel fetal movements.
Treatment for umbilical cord thrombosis
If thrombosis occurs during pregnancy and the fetus dies, it may be necessary to induce labor and remove the placenta and then perform a curettage, which is a scraping of the uterus.
In addition, if cord thrombosis occurs or is detected during delivery, the chance of fetal death is high and therefore one should act quickly to remove the baby from the uterus.
