Kim JA, Cho JY, Lee YH, Song MJ, Min JY, Lee HJ, Han BH, Lee KS, Cho BJ, Chun YK - Korean J Radiol (2003 Jan-Mar)

Bottom Line: Multifetal gestations are high-risk pregnancies involving higher perinatal morbidity and mortality, and are subject to unique complications including twin oligohydramnios-polyhydramnios sequence, twin-to-twin transfusion syndrome, acardiac twins, conjoined twins, co-twin demise, and heterotopic pregnancies.The purpose of this study is to describe the prenatal ultrasonographic and pathologic findings of these complications.

Doppler sonographic findings of twin-to-twin transfusion syndrome in a monochorionic diamniotic twin pregnancy.A. Ultrasonogram obtained at gestational age 21 weeks shows significant discrepancy in fetal sizes. Fetus A is larger than fetus B by more than 2 SD.B. Color Doppler sonogram demonstrates approximate insertions (arrows) of two umbilical cords in a single placenta.C, D. Umbilical arterial Doppler sonogram of the smaller fetus (C) depicts increased vascular resistance and absent diastolic flow, while that of the larger fetus (D) shows normal diastolic flow.

Ultrasonogram obtained at gestational age 21 weeks shows significant discrepancy in fetal sizes. Fetus A is larger than fetus B by more than 2 SD.B.

Umbilical arterial Doppler sonogram of the smaller fetus (C) depicts increased vascular resistance and absent diastolic flow, while that of the larger fetus (D) shows normal diastolic flow.

Mentions: Doppler sonography is useful for evaluating placental flow and the interfetal perfusion difference (6) (Fig. 2).
