Resultados obstétricos en cribado combinado de las aneuploidías en el primer trimestre superior al corte con resultado de amniocentesis con cariotipo fetal normal

Introduction

To evaluate whether there are adverse pregnancy outcomes in pregnant women with a risk index above the cut-off point in first-trimester screening for fetal chromosomal abnormalities and an amniocentesis result of normal fetal karyotype in a sample of pregnant women attending our clinic at the beginning of pregnancy.

Subjects and methods

We performed a case-control study. A series of patients who underwent first-trimester combined screening as part of antenatal care between January 2009 and January 2010 were selected.

Results

Of the maternal complications registered during the pregnancy, gestational diabetes was more frequent among cases.

Conclusions

The incidence of the remaining complications analyzed (intrauterine restricted growth, preeclampsia, oligoamnios) was similar in the two groups. In most of the pregnant women, delivery occurred after 37 weeks through the vaginal route.
