[Chronic twin to twin transfusion syndrome with non-immunologic hydrops fetalis "donor"]

We describe a case of twin to twin transfusion syndrome, with few distinct features that are not commonly reported. Not immunological hydrops fetalis (NIHF) was met in donor and there was no hydramnion around the recipient. In prenatal diagnosis we additionally used the ultrasound testing of the dividing membranes and the Doppler velocimetry in umbilical arteries.
