Silent rupture of an unscarred uterus at third-trimester abortion correlated with an unrecognized perforation

摘要

Silent uterine rupture in an unscarred uterus during pregnancy is rare. We present a case of silent uterine rupture in an unscarred uterus at third-trimester abortion by use of mifepristone and misoprostol in a patient who had a history of intrauterine procedures. The absence of clinical symptoms suggests that this uterine rupture resulted from an unrecognized perforation in a previous intrauterine manipulation. Routine sonographic follow-up examinations and careful clinical observations are especially recommended for women with previous intrauterine manipulations.
