Heterotopic pregnancy following administration of human menopausal gonadotropin and following in vitro fertilization and embryo transfer: two case reports and review of the literature.
We report two cases of heterotopic (combined intra- and extra-uterine) pregnancy in women treated for infertility. In the first case the patient conceived following administration of human menopausal gonadotropin. In the seventh week of gestation she had a spontaneous abortion and in the eighth week required urgent laparotomy for acute abdomen due to the rupture of pregnant right tube. In the second case the patient conceived from IVF-ET; in the eighth week a salpingectomy was made. The intrauterine pregnancy continued regularly until term and the patient was delivered of a healthy baby by caesarean section. We reviewed the literature and we found that heterotopic pregnancy is an insidious disease with a constant increase of incidence, especially in infertile women submitted to therapy for ovulation induction or assisted reproductive techniques. All the patients who have risk factors should be submitted to careful controls in early pregnancy, including an ultrasound transvaginal scan.
