Ectopic pregnancy after sequential embryo transfer: review of 22 cases

To assess the prevalence of ectopic pregnancy among women who conceived with assisted reproductive technology and to see if there is increased risk after sequential embryo transfer. The ectopic pregnancy rate for ART pregnancies was calculated among women who conceived and had ectopic pregnancy after ICSI followed by Sequential embryo transfer from an ART centre. Variation in ectopic risk by patient and ART treatment factors was assessed including Sequential transfer, risk factor for ectopic pregnancy, tubal infertility and previous ectopic pregnancy. Of 1960 women, who underwent ICSI, 1047(53.41%) had positive pregnancy, 22(2.1%) women had an ectopic pregnancy out of which 2(9%) had heterotrophic pregnancy. The mean age was 30.4±4.33. Tubal factor contributed to 31.81% cases and 27.27% had previous history of ectopic pregnancy. Sequential transfer was done in all the patients with more than one embryo transferred. There was no significant increase in the ectopic pregnancy when Sequential embryo transfer was done. Tubal factor infertility and history of previous ectopic pregnancy contributed to risk factor for ectopic pregnancy in our study. Sequential transfer did not increase the risk of ectopic pregnancy.
