Prenatal diagnosis of twin-twin transfusion syndrome complicated with hydrops fetalis at 14 weeks of gestation

Twin-twin transfusion syndrome (TTTS) may complicate multiple pregnancy. Mo nochorionic discordant twins with oligohydramnios and polyhydramnios may be diagnostic. Hydrops fetalis is particularly ominous. All the signs can app ear independently at any stage of gestation. However, TTTS with hydrops fet alis in early pregnancy is rare. We report here a case of TTTS complicated with hydrops fetalis diagnosed at 14 weeks of gestation. Our case may be on e of the earliest cases of the prenatal diagnosis of TTTS complicated with hydrops fetalis in the literature. (C) 2001 International Federation of Gyn ecology and Obstetrics.
