Fetal Diagnosis and Therapy | 2007

Objective: We examined the relation between first-trimester crown-rump length (CRL) discordance and birth weight discordance in dichorionic twin pregnancies conceived by assisted reproductive technology (ART). Methods: We examined 101 nulliparous dichorionic twin pregnancies producing male-male or female-female infants conceived spontaneously (n = 38) or following in vitro fertilization and embryo transfer (n = 63). Results: There were no significant differences in CRL disparity or birth weight discordance between spontaneous and ART-conceived dichorionic twin pregnancies. There was a positive correlation between CRL disparity and birth weight discordance in ART-conceived twin pregnancies (r2 = 0.22, p = 0.02), while there was no such correlation in spontaneous pregnancies (r2 = 0.02, p = 0.40). Conclusion: In ART-conceived dichorionic twin pregnancies, CRL disparity may be associated with birth weight discordance.

Background. We present here 2 cases of acute twin-twin transfusion occurred during vaginal labor in monochorionic-diamniotic twin pregnancies. Case. Fetal heart rate tracings showed tachycardia in the donor twin in the first case, while they showed reassuring patterns in both twins in the second case. Conclusion. These differences in changes of fetal heart rate in the donor twins following acute twin-twin transfusion may be resulted from the differences in amount of transfusion and elapsed time.

CONCLUSION In ART-conceived dichorionic twin pregnancies, CRL disparity may be associated with birth weight discordance.
