NovaSure® endometrial ablation is a successful therapy for patients with heavy menstrual bleeding who do not want to preserve fertility. However, endometrial ablation is not a contraceptive treatment. We report two cases of pregnancy after NovaSure® endometrial ablation. Case 1 is a pregnancy in a 44-year old woman. An elective abortion was performed at 9 5/7 weeks of gestational age. Case 2 is a pregnancy in a 41-year old woman which was complicated by a placenta increta. She underwent a caesarean section followed by a hysterectomy at 35 1/7 weeks of gestational age. Data on pregnancies after NovaSure® are limited. So far, 26 case reports of pregnancy after NovaSure® could be identified. Data were available for merely 11 cases. Due to the high incidence of potentially life-threatening complications, contraception is essential for all women who undergo NovaSure® endometrial ablation.
