RESUMEN

Background: Bilateral tubal ligation (BTL) is an effective permanent method of birth control that is surgically performed to block the woman's fallopian tube and prevent the egg from meeting the sperm. It is preferred by women or couples who have achieved their reproductive potential and do not desire pregnancy. BTL carries a low risk of method failure with a subsequent pregnancy which is likely to be ectopic. We present a case of two consecutive ruptured tubal ectopic pregnancies following an interval BTL. Case Presentation: A 40-year-old female, with 7 living children, who previously underwent an interval BTL, presented with acute abdominal pain for 2 days and amenorrhea for 6 weeks. She was stable but had generalized abdominal tenderness, guarding and rebound tenderness, and cervical motion tenderness. Her urine HCG was positive, and a trans-abdominal ultrasound scan revealed a tender echo-complex right adnexal mass, free fluid in the Cul-de-sac, and an empty uterine cavity, consistent with a ruptured right ectopic pregnancy. An emergency exploratory laparotomy was done with findings of a ruptured right distal tube containing products of conception, hemoperitoneum, and previous tubal ligation and left salpingectomy. A right total salpingectomy was done, and the excised right tube containing the mass was sent for histological examination, which revealed chorionic villi and hemorrhagic vascular decidual tissue in the fallopian tube, features suggestive of tubal ectopic pregnancy.
