Perinatal problems in multiple births.

BACKGROUND

Multiple pregnancies have become more common in the industrialized world because of rising maternal ages and advances in reproductive medicine.

METHODS

Selective literature review.

RESULTS

Multiple pregnancy carries a higher risk of prematurity, intrauterine growth restriction, and prenatal death, as well as elevated risks to the mother including preeclampsia, diabetes, and hemorrhage during delivery. Genetic tests and ultrasonography are the most important tests for monitoring during pregnancy. Ultrasound aids in the detection of the feto-fetal transfusion syndrome and in the determination of zygosity.

CONCLUSIONS

The care of women with multiple pregnancies requires the collaboration of specialists in prenatal medicine, obstetrics, and neonatology as well as a properly functioning integration of outpatient and inpatient care.
