Two ectopic pregnancies were discovered in a group of 59 patients who conceived although each was wearing an intrauterine contraceptive device. All had been admitted over a 9-month period for therapeutic abortion. During this same period, the therapeutic abortion service admitted 3182 other women all of whom never wore an intrauterine contraceptive device. Only 2 ectopic pregnancies were detected among this large group. The significant difference between the rate of ectopic to intrauterine gestations among patients who used an intrauterine device, compared with those who did not, was analyzed. A plan of management, which includes a high index of suspicion, is proposed for the pregnant patient whose history includes the use of an intrauterine device at the time of conception.
