# Maternal and Neonatal Outcome of Surviving Twin after Single Fetal Demise at 17 Weeks: A Case Report

## TL;DR

A mother and surviving twin had favorable outcomes after a 10-week pregnancy extension following fetal loss at 17 weeks in a twin pregnancy.

## Contribution

This case report highlights a rare instance of prolonged monochorionic twin pregnancy after fetal demise with positive maternal and neonatal outcomes.

## Key findings

- Pregnancy was prolonged by 10 weeks after fetal demise at 17 weeks.
- The surviving twin required NICU care but improved and was discharged after two months.
- Mother experienced no major complications despite the extended pregnancy.

## Abstract

Single fetal demise in a monochorionic diamniotic twin pregnancy poses significant risks to both mother and the surviving twin. We report a monochorionic diamniotic twin pregnancy where one fetus demised at 17 weeks, and pregnancy was prolonged by 10 weeks with expectant management. At 28+3 weeks, an emergency cesarean section was performed for preterm premature rupture of membranes. The mother had no major complications. The surviving twin weighed 1350 grams at birth and required neonatal intensive care unit care for respiratory distress and sepsis but showed significant improvement and was discharged after two months. This case is unique due to 10-week prolongation after single intrauterine fetal death, especially with favorable maternal and neonatal outcome.
