B19 parvovirus-induced fetal hydrops:good outcome after intrauterine blood transfusion at 18 weeks of gestation.

We report a successful treatment of a B19 parvovirus-induced fetal hydrops diagnosed at 16 weeks of gestation. This disease could be corrected by means of a unique intraperitoneal blood transfusion performed at 18 weeks, once diagnosis was established. The delivery occurred at 36 weeks, leading to the birth of a healthy baby. This case suggests that transfusion should be attempted, as the spontaneous fetal recovery remains uncertain and shows that intraperitoneal blood transfusion is an effective therapeutic option of the B19 parvovirus-induced anemia, in the absence of a viral myocarditis.
