Uterine torsion in second trimester of pregnancy followed by a successful-term pregnancy.

Uterine torsion is defined as rotation of the uterus of more than 45° on its long axis. It is an unusual complication of pregnancy and for most obstetricians it probably represents a 'once-in-a-lifetime' diagnosis. Fetal mortality up to 12% and occasional maternal mortality are reported. A 22-year-old second gravida presented at 22+ weeks gestation with severe abdominal pain and shock. Laparotomy was done for suspected abruptio placenta, when torsion of the uterus to 180° was diagnosed. Posterior hysterotomy was performed. She conceived the next year and was delivered at term by caesarean section. Uterine torsion is a rare complication of pregnancy and obstetricians should have this complication in mind when performing a caesarean section for undiagnosed severe abdominal pain in pregnancy. Anatomical landmarks should be defined if possible, prior to uterine incision during a caesarean section, to avoid posterior hysterotomy.
