Complete Velamentous Insertion

Complete Velamentous Insertion (CVI) is a condition that occurs during pregnancy where the umbilical cord is not attached to the placenta in the normal way. Instead, it inserts into the fetal membranes, away from the placental edge. This can pose risks to both the mother and the baby and requires careful monitoring and sometimes medical intervention.

Types of Complete Velamentous Insertion:

1. Bilobed Placenta with Velamentous Cord Insertion: In this type, the placenta is divided into two lobes, and the umbilical cord inserts into the fetal membranes rather than the placental tissue.
2. Unilobed Placenta with Velamentous Cord Insertion: Here, the placenta is a single lobe, but the umbilical cord inserts into the membranes instead of the placenta.

Causes of Complete Velamentous Insertion:

1. Genetic Factors: Certain genetic factors may predispose a woman to have a complete velamentous insertion.
2. Abnormal Placental Development: Issues during placental development can lead to this condition.
3. Previous Pregnancy with CVI: Women who have had CVI in previous pregnancies may be at higher risk for it in subsequent pregnancies.
4. Maternal Age: Advanced maternal age may increase the likelihood of CVI.
5. Assisted Reproductive Techniques: Some fertility treatments may increase the risk of CVI.
6. Smoking: Smoking during pregnancy can contribute to various pregnancy complications, including CVI.
7. Multiparity: Women who have had multiple pregnancies may have a higher risk of CVI.
8. Uterine Abnormalities: Certain abnormalities in the shape or structure of the uterus can increase the risk.
9. Infections: Infections during pregnancy can affect placental development and increase the risk of CVI.
10. Maternal Health Conditions: Conditions such as hypertension? or insulin? is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।" data-rx-term="diabetes" data-rx-definition="Diabetes is a condition where blood sugar stays too high because insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।">diabetes? can increase the risk.
