Clinical presentation and outcome of 20 fetuses with parvovirus B19 infection complicated by severe anemia and/or fetal hydrops

Abstract

Despite active management by transfusion in fetuses with parvovirus B19 infection, mortality remained substantial during the acute phase of anemia and fetal hydrops. Regression of effusion appears to be an important variable for prognosis. Non-anemic forms exist with isolated refractory ascites or pleural effusion. Maternal mirror syndrome appears to reflect the intensity and persistence of the fetal anemia.
