Polyhydramnios and oligohydramnios in twin gestations

Area of Science:

• Perinatology
• Maternal-Fetal Medicine
• Twin Gestation Studies

Background:

• Twin pregnancies present unique challenges in prenatal care.
• Concurrent polyhydramnios (excess amniotic fluid) and oligohydramnios (low amniotic fluid) is a rare but serious complication.
• The simultaneous presence of both conditions in twins has not been extensively studied.

Purpose of the Study:

• To investigate the perinatal outcomes of twin pregnancies complicated by concurrent polyhydramnios and oligohydramnios.
• To determine the impact of gestational age at diagnosis on fetal survival.
• To evaluate the effectiveness of various therapeutic interventions.

Main Methods:

• Retrospective case series analysis of seven twin pregnancies.
• Inclusion criteria: concurrent polyhydramnios and oligohydramnios.
• Data collection included gestational age at diagnosis, interventions, and perinatal outcomes.

Main Results:

• A perinatal mortality rate of 71% was observed in the studied cohort.
• All fetuses (100%) died when the complication occurred before 26 weeks' gestational age.
• Survival rates were not significantly improved despite diverse therapeutic approaches.

Conclusions:

• Concurrent polyhydramnios and oligohydramnios in twin pregnancies is associated with extremely high perinatal mortality.
• Early onset (before 26 weeks) portends a universally fatal outcome.
• Current therapeutic strategies appear ineffective in improving survival for this severe complication.
