PERSISTENCE OF PARTIAL MOLAR PLACENTA AND SEVERE PREECLAMPSIA AFTER SELECTIVE TERMINATION IN A TWIN PREGNANCY

Background: Triploid molar pregnancies are usually managed by evacuati on of the uterine contents. Case: A 25-year-old woman had a clomiphene citrate-induced twin pregnancy. Ultrasound scan at 13 weeks revealed one anomalous twin. Cytogenetic analysis revealed a karyotype of 69,XX Y and a normal other twin. In an attempt to salvage the normal fetus, selective termination was successfully performed at 15 weeks by intrac ardiac potassium chloride injection. However, the placenta continued t o grow and severe preeclampsia developed at 19 weeks, requiring pregna ncy termination. Conclusion: Selective termination of a triploid twin does not guarantee resolution of molar growth and sequelae of the mole ; severe preeclampsia can still develop.
