# Prenatal Ultrasound Diagnosis of Vasa Previa With Careful Intraoperative Management: A Case Report

## TL;DR

A case report shows how prenatal ultrasound diagnosed vasa previa, leading to a successful cesarean delivery with careful management.

## Contribution

This case emphasizes the importance of prenatal ultrasound in identifying vasa previa and guiding safe cesarean delivery.

## Key findings

- Prenatal ultrasound successfully diagnosed vasa previa at 33 weeks gestation.
- Elective cesarean section with careful membrane separation ensured fetal safety.
- The baby was discharged after six days in the neonatal intensive care unit.

## Abstract

Vasa previa is a rare but potentially life-threatening condition to the fetus. Timely antenatal diagnosis and delivery by cesarean section (CS) can lead to a favorable outcome. Here, we report a case of recurrent pregnancy loss (G3A2) with vasa previa, which was diagnosed prenatally by ultrasound. She was admitted at her 31st week with bleeding per vaginum (PV) provisionally diagnosed as antepartum hemorrhage (APH) and managed conservatively as placenta previa. Follow-up ultrasonography (USG) revealed vasa previa at 33 weeks. The fetus was delivered by lower segment cesarean section (LSCS) after careful separation of the membranes and avoiding damage to the vessels as there was velamentous insertion of cord with the lower margin of the placenta in the lower segment. The baby was cared for in the neonatal intensive care unit due to prematurity and discharged after six days. This case report highlights the importance of prenatal ultrasound in diagnosing vasa previa and planning an elective cesarean section with caution intraoperatively for the safe delivery of the baby.
