Pregnancy in a patient with a displaced levonorgestrel-releasing intrauterine system: a case report.
We report the case of a 39-year-old woman who became pregnant despite a levonorgestrel-releasing intrauterine system (LNG-IUS), which was inserted 40 months before the pregnancy was detected. When a Caesarean section was performed, the LNG-IUS was found within the omentum majus. It has been reported, that displaced LNG-IUS can cause amenorrhea and high plasma levels of LNG in affected women, probably due to the higher resorptive capacity of the peritoneum, recommending a removal of the displaced LNG-IUS. Our case report demonstrates that a dislocated LNG-IUS does not necessary has the ability to suppress ovulation and therefore pregnancy. Therefore, every gynaecologist should be aware of a pregnancy despite a dislocated LNG-IUS.
