[Doppler ultrasound study of a twin pregnancy with feto-fetal transfusion syndrome].

A report is made on a typical case of twin-twin transfusion syndrome of monozygotic twins with severe polyhydramnios. By treatment with decompression amniocentesis, we achieved prolongation of the pregnancy by 10 weeks. Daily performed Doppler velocimetry showed, that the resistance values did not differ before and after amniocentesis. We found the greatest differences between the pulsatility indices of the umbilical cords and the aortae. The arteriovenous anastomosis was visualized by colour flow mapping.
