LOCAL MEDICAL-TREATMENT OF INTERSTITIAL PREGNANCY AFTER INVITRO FERTILIZATION AND EMBRYO TRANSFER (IVF-ET) - 2 CASE-REPORTS

Two cases of interstitial pregnancy (one singleton, one heterotopic tw ins) were confirmed 31 and 34 days after in-vitro fertilization. Serum human chorionic gonadotrophin concentrations were 35 000 and 86 000 m IU/ml, respectively. They were treated conservatively with transvagina l ultrasonically guided intra-ovular injection of either methotrexate in the singleton pregnancy, or potassium chloride into the ectopic sac of the heterotopic twins. No complications were observed. The intra-u terine pregnancy continued and the patient delivered a 3350 g healthy baby at 39 weeks.
