Abstract

Twin reversed arterial perfusion (TRAP) sequence is a rare specific anomaly of twin gestation with fused placenta and umbilical anastomosis. This syndrome occurs once in about 34,600 births and reported first by Beneditti in 1533. We report on prenatal diagnosis of a case of TRAP sequence with color Doppler sonography, this case is presented with a brief review of the literature.
