Spontaneous uterine rupture with amniotic sac protrusion at 28 weeks subsequent to previous hysteroscopic metroplasty.

Background: Hysteroscopic metroplasty improves pregnancy outcome in case of uterine septum. Uterine rupture during a pregnancy following this procedure may occur.

Methods: A patient with a history of hysteroscopic resection of a uterine septum complicated by fundal perforation, presented at 28 weeks a spontaneous uterine rupture with amniotic sac protrusion through the uterine wall disruption.

Conclusions: Uterine rupture during pregnancy following a hysteroscopic metroplasty may occur even though it appears to be a very uncommon event. Patients who have had this procedure should be aware of this potential risk in case of future pregnancies. How to avoid such complication is still unclear.
