Velamentous cord insertion
Velamentous Cord Insertion[edit | edit source]
Velamentous Cord Insertion is a condition in obstetrics where the umbilical cord inserts into the fetal membranes (chorion and amnion), rather than the central mass of the placenta. This insertion typically occurs on the extraplacental membranes, which can lead to a variety of complications during pregnancy and childbirth.
Definition and Characteristics[edit | edit source]
In Velamentous Cord Insertion, the umbilical cord's blood vessels travel a certain distance within the membranes before reaching the placenta. This contrasts with the normal situation where the cord inserts directly into the placental mass.
Clinical Significance[edit | edit source]
This condition is clinically significant for several reasons:
- The vessels are unprotected by Wharton's jelly and hence are more vulnerable to compression and rupture.
- There is an increased risk of vasa previa, where the blood vessels cross the internal opening of the cervix.
- It can be associated with intrauterine growth restriction (IUGR) and preterm birth.
Diagnosis[edit | edit source]
Velamentous Cord Insertion is typically diagnosed through ultrasound imaging during routine prenatal care. The diagnosis is crucial for planning safe delivery strategies to mitigate risks.
Management and Care[edit | edit source]
Management of pregnancies with Velamentous Cord Insertion involves careful monitoring and planning. This may include:
- Regular ultrasound scans to monitor the position of the vessels and the growth of the fetus.
- Considering Cesarean section (C-section) for delivery if vasa previa or other complications are present.
Risk Factors and Prevalence[edit | edit source]
Velamentous Cord Insertion is more common in pregnancies with multiple gestations, in women of advanced maternal age, and in those who have undergone in vitro fertilization (IVF).
