Resolution of superimposed pre‐eclampsia, and improvement in umbilical artery flow in a surviving twin after intrauterine demise of its co‐twin

Pre‐eclampsia has a progressive clinical course, and is only cured by delivery of the placenta. We report a 30‐year‐old G1P0 with dichorionic twins, discordant growth and chronic hypertension who developed superimposed pre‐eclampsia in her 21st week of gestation. After intrauterine demise of the severely growth‐restricted twin, the superimposed pre‐eclampsia resolved. The surviving twin initially had absent end diastolic flow, which resolved after the demise. A healthy 1935‐g neonate with Apgar 9/9 was delivered at 34 weeks. Antenatal resolution of pre‐eclampsia is extremely rare and resolution of superimposed pre‐eclampsia has not, to our knowledge, been reported.
