Lower segment uterine rupture related to early pregnancy by in vitro fertilization and embryo transfer after a previous cesarean delivery.

A 31-year old woman with secondary infertility after a previous Cesarean delivery underwent in vitro fertilization and embryo transfer (IVF-ET). She was pregnant by IVF-ET. In the first trimester, however, she began to have genital bleeding and lower abdominal pain. This led to intrauterine fetal death, which was terminated by curettage of the uterine cavity. Later, magnetic resonance imaging (MRI) showed the uterine pregnancy on the lower segment scar and the rupture, which was abdominally repaired. It is very likely that the uterine rupture was associated with the implantation in the Cesarean section's scar in this case.
