The association between vasa previa, multiple gestations, and assisted reproductive technology

Area of Science:

• Maternal-Fetal Medicine
• Obstetrics
• Perinatology

Background:

• Vasa previa, a rare but serious obstetric complication, involves fetal blood vessels running near the internal cervical os.
• Risk factors include multiple gestations, low-lying placentas, velamentous cord insertions, and assisted reproductive technology.
• Prompt diagnosis and management are crucial to prevent fetal hemorrhage and mortality.

Purpose of the Study:

• To outline diagnostic considerations for vasa previa in high-risk pregnancies.
• To propose a management strategy for vasa previa in the context of multiple gestations.

Main Methods:

• Review of clinical risk factors for vasa previa.
• Emphasis on serial ultrasound surveillance for fetal well-being and placental assessment.
• Discussion of optimal timing for delivery and antenatal interventions.

Main Results:

• Patients with multiple gestations, low-lying placentas, velamentous cord insertions, and a history of assisted conception warrant careful evaluation for vasa previa.
• Serial surveillance for signs of preterm labor is recommended.
• Elective cesarean delivery between 34 and 35 weeks' gestation, following corticosteroid administration for fetal lung maturity, is a viable management approach.

Conclusions:

• Vasa previa in multiple gestations necessitates vigilant monitoring.
• A proactive management plan involving surveillance and timely, elective cesarean delivery can improve fetal outcomes.
