Twin pregnancies discordant for digynic triploidy – A case series

Abstract

Objective: To analyse natural course and perinatal management in twin pregnancies discordant for digynic triploidy. Case report: We present five cases of twins discordant for digynic triploidy. Pregnancy outcome was known for three of them. In one case, premature rupture of membranes occurred at 20 gestational weeks and both fetuses were miscarried. In two other pregnancies healthy co-twins were born at term after the triploid fetuses demise at 28 and 37 weeks. No maternal complications were observed. Conclusion: Twin pregnancies discordant for triploidy poses a challenge for perinatal management. Expectant management should be considered in digynic triploid cases.
