At 13 weeks' gestation both fetuses presented with increased nuchal translucency (NT) and cardiomegaly. In both cases pulsed Doppler ultrasound examination of the fetal middle cerebral artery (MCA) revealed increased peak systolic velocity (PSV), which led to a suspicion of fetal anemia. Maternal PV infection was confirmed by a positive polymerase chain reaction result. Each fetus received a 3\u2010mL intravenous transfusion of packed red blood cells into the umbilical vein, using a 25\u2010G spinal needle. Follow\u2010up ultrasound and Doppler examination demonstrated fetal well\u2010being, decline of the MCA\u2010PSV and resolution of the NT. Case 1 was readmitted at 25 weeks' gestation with severe hydrops fetalis, and both mother and fetus still tested positive for PV\u2010B19 DNA. Three more intrauterine blood transfusions were performed and the fetal hydrops resolved. In Case 2 no additional transfusions were needed. Both babies had a good neonatal outcome and uneventful follow\u2010up. Our findings demonstrate that the MCA\u2010PSV is helpful in establishing the diagnosis of first\u2010trimester fetal anemia. Intravasal transfusion can be attempted as early as the first trimester. Copyright \u00a9 2007 ISUOG.
