Antepartum detection of cord presentation by transvaginal ultrasonography for term breech presentation: potential prediction and prevention of cord prolapse.

Aim: We evaluated the efficacy of antepartum screening for cord presentation by trans-vaginal ultrasonography (TVS) on predicting and preventing umbilical cord prolapse (UCP) in term breech delivery.

Methods: We investigated every woman with a breech-presenting fetus for cord presentation by weekly TVS after 36 weeks of gestation since 1995. If the cord was found in advance of fetal presenting parts, we recommended her to undergo elective cesarean section to avoid UCP.

[Organ transplantation and pregnancy].

Organ transplantation in reproductive-age women increases in frequency each year. In the presence of stable graft function and stable maintenance immunosuppressive regimens, patients are more likely to have successful outcomes. It is reasonable to advise recipients to wait at least 2 years after transplant to become pregnant.

Cyclic changes in the umbilical arterial flow in mono-chorionic, di-amniotic twin pregnancy.

Objective: To determine the effect of arterio-arterial anastomosis on the umbilical arterial flow in mono-chorionic, di-amniotic twin pregnancy.

Subjects: Thirty-three women with mono-chorionic, di-amniotic twin pregnancy.

Methods: Pulsed Doppler ultrasonographic examination was performed every 4 weeks to obtain umbilical arterial flow velocity waveforms in both two fetuses.
