Simultaneous intrauterine and ectopic pregnancies following in-vitro fertilization and gamete intra-fallopian transfer. A review of nine cases

Abstract

This paper reports nine cases of simultaneous intrauterine and ectopic pregnancies which followed in-vitro fertilization (three cases) and gamete intra-Fallopian transfer (six cases). The ectopic pregnancies were treated by aspiration and injection of potassium chloride and methotrexate (five cases), salpingectomy (three cases) or laparoscopic evacuation (one case). In five of the nine patients the intrauterine pregnancies continued until after the 35th week and the patients delivered live infants. The role of vaginal ultrasound scanning in making the diagnosis was emphasized. The literature on heterotropic pregnancy is reviewed.
