Acute Feto-Fetal Transfusion Simulation in Monochorionic Diamniotic Twins

Introduction: Acute feto-fetal transfusion (F-F TRF) is a serious complication affecting exclusively monochorionic multiple pregnancies. The pathophysiological background is feto-fetal exsanguination in the presence of interfetal placental vascular anastomoses. The risk of the death or neurological disability of the surviving twin in case of the co-twin demise is 15% and 30% respectively, regardless of clinical subtype.
