1. Introduction A 38-year-old woman was admitted to the Department of Gynecology, Shenzhen Hospital of Integrated Traditional Chinese and Western Medicine, with the complaint of “menstrual volume reduction for 2 years after abortion.” The patient had regular menstruation for 5/28–32 days. The menstrual volume decreased by one-half after abortion 6 years ago, and 2–3 daily sanitary pads (one-third soaked) were used daily for 4 days. The menstrual period can extend to 6–7 days without dysmenorrhea.

1. Introduction An ectopic pregnancy (EP) is a condition in which a fertilized egg is implanted outside the uterine cavity. The prevalence of EPs has increased from 0.5% to 2% since 1970 and remains the most common cause of pregnancy-related death in the first trimester (1, 2). Implantation usually takes place in the ampullary part of the fallopian tube, and less often intra-abdominally or in the cervix. In 2.4% of cases, the interstitial part of the fallopian tube is implanted (3).
