Ectopic Pregnancy Observed With Kyleena Intrauterine Device Use: A Case Report

Kyleena (levonorgestrel 19.5 mg), a type of intrauterine device (IUD), has an efficacy rate of 99% in preventing pregnancy. Because the overall failure rate of IUDs is low, ectopic pregnancy (EP) with IUD use is uncommon. This case reports an EP observed in a female with the Kyleena IUD in place. She had no known risk factors for an EP, which makes this case noteworthy. Ultrasound and surgery confirmed a 4 cm EP in the ampulla of the left fallopian tube. Insufficient evidence exists to conclude whether the Kyleena IUD has a higher risk of EP compared to other hormonal IUDs. As the Kyleena IUD becomes a more popular option for women in search of an effective contraceptive, patients and clinicians should be aware of this potential risk. Our case emphasizes that continued research on the prevalence of EP with Kyleena use is necessary.
