Multifetal pregnancy reduction (MFPR) after infertility treatment

From January 2001 to September 2001, MFPR were performed for 26 multifetal pregnancies after infertility treatment. Transvaginal selective embryo aspiration was performed at the ninth week of gestation, without KCl injected in the vicinity of the fetal heart. The mean number of viable embryos before and after reduction was 3.4 and 2.1. There were no complications recorded after the procedure such as vaginal bleeding, amniotic leakage and infection. The rate of miscarriage before 24 weeks was 7.1%. The mean gestation length and the mean birth weight were 36.22.8 weeks and 2360.0349.4g for the twins, respectively, and 30.67.6 weeks and 2066.7177.9 g for the triplets. Results from this study were comparable to the other studies worldwide. Preliminary data from this study showed that early transvaginal embryo aspiration without using KCl is a safe, effective method to improve obstetric outcome of multifetal pregnancies after infertility treatment.
