Vasa Previa

Subject: Midwifery I (Theory)

Overview

Vasa Previa is an uncommon syndrome in which umbilical blood vessels cross the fetal membranes of the lower uterine segments without being supported by the umbilical cord or the placenta above the cervix. This blood vessel, which is important in the baby's circulation, grows along the membranes in the lower portions of the uterus at the cervical opening. When the problem is not diagnosed, blood vessels rupture during labor. The specific origin is unknown, however connected reasons include a low-lying placenta, multiple pregnancies, velamentous cord insertion, and a placenta with auxiliary lobes and a succenturiate lobe. Symptoms include painless vaginal bleeding in the third and second trimesters and fetal cardiac deceleration during labor. In such cases, a Cesarean section is recommended.

Vasa Previa is an uncommon disease in which umbilical blood arteries cross the lower uterine membranes without being maintained by the umbilical cord or the placenta above the cervix. This blood vessel, which is involved in the circulation of the infant, grows along the membranes in the lower portions of the uterus at the cervical opening. Blood vessels break during labor if the problem is not detected.

Causes

  1. Unknown but associated with:
    • The placenta is low-lying.
    • Pregnancies in multiples
    • Cord insertion via the velum
    • The placenta has supplementary lobes as well as a succenturiate lobe.

Symptoms

  • Painless vaginal bleeding in the third and second trimesters
  • Deceleration of the fetal heart during labor

Diagnosis

  • Taking a history Physical examination
  • Ultrasound Doppler

Management

  • A cesarean section is recommended.
Things to remember
  • Vasa Previa is an uncommon disease in which umbilical blood arteries cross the lower uterine membranes without being maintained by the umbilical cord or the placenta above the cervix.
  • This blood vessel, which is involved in the circulation of the infant, grows along the membranes in the lower portions of the uterus at the cervical opening.
  • Blood vessels are ruptured during labor if the problem is not detected.
  • The specific origin is unknown, however connected causes include a low-lying placenta, multiple pregnancies, voluminous cord insertion, and a placenta with auxiliary lobes and a succenturiate lobe.
  • Symptoms include painless vaginal bleeding in the third and second trimesters, as well as fetal cardiac deceleration during labor. A cesarean section is preferred in such cases.
Questions and Answers

Vasa previa is an uncommon disorder in which the umbilical cord or the placenta above the cervix do not support the umbilical blood vessels as they cross the fetal membranes of the lower uterine segments. These blood vessels, which play a role in the baby's circulation, develop along the uterine membranes at the cervical opening in the lowest region of the uterus. Blood vessels rupture during labor when the problem is not detected.

Causes

  • Unknown but connected to:
    • Placenta lying low
    • Several pregnancies
    • Velamentous cord insertion
    • Placenta with succenturiate lobe and accessory lobes

Symptoms

  • 3rd and 2nd trimesters' painless vaginal bleeding
  • Deceleration of the fetal heart during labor
