Summary
Vasa previa, a rare pregnancy complication, can cause fetal death if membranes rupture before diagnosis. Early detection and intervention are crucial for preventing fetal distress and mortality.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
Background:
- Vasa previa is an uncommon but high-risk obstetrical complication.
- Failure to diagnose vasa previa before membrane rupture can lead to fetal demise.
Observation:
- A case of perinatal hemorrhage due to vasa previa with a bilobed placenta, missed by antepartum ultrasound, is presented.
- Literature review on vasa previa, bilobed placenta, and succenturiate placenta from 1965-2002 was conducted.
Findings:
- Risk factors for vasa previa are identified, and ultrasound technology has improved diagnostic capabilities.
- Transvaginal color Doppler ultrasound is recommended for high-risk pregnancies, though its accuracy and the condition's incidence remain unknown.
- Antepartum diagnosis improves outcomes but does not eliminate all risks.
Implications:
- A high index of suspicion for vasa previa is necessary during labor, particularly at amniotomy.
- Improved diagnostic strategies are needed to reduce fetal morbidity and mortality associated with vasa previa.
