Uterine rupture during second trimester abortion with misoprostol.
BACKGROUND
Data are limited regarding the use of misoprostol in the midtrimester, therefore few cases with uterine rupture during the second trimester with a previous uterine scar have been reported in the literature.


METHODS
A 23-year-old woman with a prior low transverse cesarean section presented at 26 weeks' gestation for pregnancy termination for a fetal abnormality. She was given 200 microg misoprostol intravaginally every 3 h until regular contractions began. After the fourth dose, she had vaginal bleeding and severe contractions. She aborted completely 2 h later after the last dose. Uterine rupture was diagnosed at the previous cesarean section scar by manual vaginal examination. She underwent emergency laparotomy and the uterus was repaired.


CONCLUSIONS
Misoprostol use in the second trimester in a woman with a uterine scar can trigger severe contractions that can lead to uterine rupture.
