Selective feticide reverses intrahepatic cholestasis of pregnancy in twins discordant for growth: A case report

Abstract

Twin gestations are associated with an increased risk of intrahepatic cholestasis in pregnancy (ICP), probably attributed to the elevated pregnancy hormones. We report a case of a dichorionic diamniotic twin pregnancy, at the third trimester, complicated with ICP and severe, selective fetal growth restriction (sFGR). A 32-year-old primiparous woman with a dichorionic, diamniotic twin gestation conceived via in vitro fertilization (IVF) presented with pruritus at the maternity care unit at 26+4 weeks of pregnancy. Following a detailed assessment, she was diagnosed with severe sFGR and ICP. During her hospitalization, selective feticide of the FGR fetus was decided and a remarkable improvement in the symptoms and the laboratory findings of ICP was noticed. The incidence of ICP is reported to be higher in twin pregnancies, especially those conceived via IVF, compared with singletons. The optimal timing of delivery and management of twin pregnancies complicated with ICP remain unclear. In our case, selective reduction of the FGR fetus led to the resolution of ICP.
