Luteal phase pregnancy after mirena coil insertion for intrauterine septum resection

Abstract

This report is of an unusual case of an intrauterine singleton pregnancy with a Mirena Coil (IUS) in situ following an elective hysteroscopic intrauterine septum resection for treatment of primary subfertility in a 27-year-old female. The patient elected to continue with the pregnancy and underwent additional monitoring via ultrasound. A caesarean section was undertaken at 39-weeks gestation and a healthy male infant was born. The Mirena coil was recovered intraoperative and was visualised in the placental membranes. Pregnancy occurring with Mirena coil insertion as an adjunct to hysteroscopic septum resection in our case is an unusual clinical scenario with no management recommendations and limited recorded outcomes. Therefore, this case demonstrates potential management of such a case and learning points for intrauterine septum excision in the context of primary subfertility.
