Intrauterine pregnancy after salpingectomy for tubal pregnancy due to emergency contraception: a case report.

Ectopic pregnancy (EP) is the fourth most frequent cause of maternal death in the United Kingdom, and it is the main cause of maternal death during the first trimester in the United States. The Fallopian tubes are the most frequently affected site by EP. The main causes of tubal pregnancy are salpingitis, previous tubal surgeries, and alteration in tubal motility mainly due to the use of certain contraceptive methods. Most recently, the use of 750 μg of levonorgestrel as an emergency contraceptive method has been identified as another risk factor for EP. The diagnosis of an EP before rupture permits conservative treatment in order to preserve subsequent patient fertility. However, the conservative approach might be questioned because it is associated with a higher recurrence rate when compared with salpingectomy. Additionally, salpingectomy does not change subsequent patient fertility when (i) the contralateral tube seems to be healthy, (ii) the patients are younger than 30 years, and (iii) there is no previous history of infertility. In these patients, subsequent intrauterine pregnancy rate reaches approximately 70% at 2 years. We report here a case of intrauterine pregnancy (IUP) that occurred after salpingectomy in a patient previously undergoing tubal pregnancy without any apparent risk factors for EP other than the use of emergency contraceptive pills containing 0.75 mg levonorgestrel (Postinor 2).
