Resumo
Aims: To make a review article on ectopic pregnancy (EP) in high complexity fertilization, to define the epidemiological and reproductive profile of women carriers of EP, to evaluate the prevalence of EP after in vitro fertilization (IVF) and to verify if the transfer of frozen embryos reduces the rates of EP. METHODS: All fresh and frozen embryos transfers obtained through IVF via ICSI conducted between January 2007 and December 2014 were reviewed. Clinical pregnancies characterized by the visualization of an intrauterine gestational sac or ectopic pregnancy were included in the evaluation. Ectopic pregnancies were diagnosed by ultrasonography and / or laparoscopy. The prevalence of EP and the comparison of the rates between fresh and frozen embryos transfers were analyzed by logistic regression using the SPPS software version 15.0. Results: Of the 933 embryos obtained through IVF that resulted in clinical pregnancies, 19 cases of EP were found. The fertilization with fresh embryos resulted in 772 clinical pregnancies (group I), and 161 with frozen embryos (group II). The global prevalence of EP was 2.02%. When considered by group, group one had 16 EP that represented a rate of 2.1% and group two had a rate of 1.9%. There was a lower rate of ectopic pregnancy with frozen embryos in comparison to fresh embryos, although this did not demonstrate statistical significance (p=0.86)(OR=0.89, IC=0.258-3.11). CONCLUSIONS: The reproductive profile of patients that exhibit EP was of young female with young partner, good ovarian response and that had more than 3 embryos transferred. The prevalence of EP in this study was 2.02. It was observed that there was no significant difference in the occurrence of EP when both groups, frozen and fresh embryos, were compared.
