Chorionicity and perinatal complications in twin pregnancy: a 10 years case ser...
Descrição
OVERVIEW AND AIMS: Multiple pregnancy accounts for about 3% of all pregnancies. The monochorionic pregnancy presents a relatively constant incidence (1:250 pregnancies) unlike the dichorionic, which is influenced by race, heredity, maternal age, parity and medically assisted procreation. The purpose of this work was to evaluate the impact of chorionicity on perinatal morbidity of twin pregnancy.Retrospective, longitudinal, descriptive and analytical study of women with twin pregnancy whose birth occurred in our maternity hospital since January/1999 until December/2008. Inclusion criteria: monochorionic and dichorionic twin pregnancies confirmed by ultrasound. Exclusion criteria: monochorionic monoamniotic gestation. Demographic data, delivery variables and perinatal morbidity and mortality were studied. Data were evaluated using the χ2 test (qualitative variables), t-Student (continuous quantitative variables) and Mann-Whitney test (quantitative discrete variables).We studied 504 pregnancies (356 dichorionic diamniotic and 148 monochorionic diamniotic). The monochorionic pregnancy had a higher incidence of threatened preterm labor (43,9% vs 31,5%, p OVERVIEW AND AIMS: Multiple pregnancy accounts for about 3% of all pregnancies.
