Repeat ectopic pregnancy. A twenty-year hospital survey.

Seventy-two patients with repeat ectopic pregnancy including 3 women with three ectopic pregnancies each during the period 1965 to 1984 were studied. In the same period there was a total of 842 ectopic pregnancies, giving a repeat ectopic pregnancy incidence of 9.4%. In the last decade the incidence of repeat ectopic pregnancy was 10.4%, and in the first decade it was 7.0% (p less than 0.025). None of the women used an intra-uterine contraceptive device, among those with repeat ectopic pregnancy in the first decade, vis-à-vis 17 (30.4%) in the last decade. A history of infertility was common among the patients with repeat ectopic pregnancy. Between the two events there was a total of 17 deliveries in 13 patients. Four out of 24 potentially fertile women completed full-term pregnancies following their second ectopic pregnancy.
