Umbilical Vein Varix Size, Symptoms, Causes, Management, Treatment

Umbilical cord varix is a condition in which an umbilical vein of the umbilical cord become dilated. The word varix defines the abnormal enlargement of the umbilical vein. Placenta joins the fetus with the uterine wall. Placenta is an organ which is reddish brown in color and connects fetus with uterine wall via umbilical cord. Umbilical cord contains two main arteries and one vein which is responsible for blood supply. The function of placenta is to supply nutrients to the fetus from mother. Umbilical vein varix is a rare condition with unknown cause. The risk factors are also unidentified.

Umbilical Vein Varix Causes


Talking about the causes of abnormal dilation of umbilical vein, the exact reason is still unknown. This condition is still under investigation to check the exact cause or relevant cause. It is estimated that the do's and don'ts of mother does not contribute to the occurrence of umbilical vein varix. Other than unknown causes, the risk factors of umbilical vein varix are also unknown. There are no predisposing factors which contribute to the occurrence of umbilical vein varix. Researchers are still trying to find the relevant causes and risk factors of umbilical vein varix.

Umbilical Vein Varix Size, Symptoms, Causes, Management, Treatment

Umbilical Vein Varix Size


The dilation of the umbilical vein is abnormal and it may dilate up to a dangerous level. Usually the size of umbilical vein increases due to an increase in the diameter. The diameter of the umbilical vein increases up to 3mm in the gestation periods (at 15 weeks) and this may further increase to 8mm at term. The size of umbilical vein can be diagnosed with the help of ultrasound technique during Doppler examination. Doppler examination clearly shows the enlarged size of umbilical vein. The symptoms are common like problem in the blood pressure so proper examination is required.

Umbilical Vein Varix Management


The treatment and management of the umbilical vein varix is necessary for the maintenance of health of fetus. The clinical guidelines for the management of umbilical vein varix are not clear. The variables which should be managed are the diameter of varix, problems in the turbulent flow of blood ( the turbulent flow increase or decrease) and the anomalies of fetus. All these variables require management for the good health of fetus and delivery. This is because, most deliveries with umbilical vein varix are associated with thrombotic varix, turbulent flow and multiple malformations.

Umbilical Vein Varix Treatment


There is not any specific treatment for umbilical vein varix. If there are any complications associated with it, then supportive and symptomatic treatment is required to treat the symptoms. In case of fetal distress, an elective delivery is required. A regular, periodic and careful  monitoring is required during pregnancy. If the umbilical vein varix is diagnosed during pregnancy then it may prove fatal for mother and fetus because the pressure of umbilical vein increases. As this condition does not depend on the do's and don'ts of mother during or before pregnancy so it should not be considered.
