Among them, 95.9% were diagnosed with trisomy 18 prenatally. Prenatal ultrasound findings showed fetal growth restriction in 77.2%, polyhydramnios in 63.4% and congenital heart defects in 95.1%. For 18 cases, cesarean section (<jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>\u2010section) was chosen, and for 75 cases, transvaginal delivery was chosen. Premature delivery occurred in 35.5%. Stillbirths occurred in 50 cases (40.7%). Fetal demise before onset of labor occurred in 30 cases and fetal demise during labor occurred in 20 cases which was 26.7% of vaginal deliveries. Among the 73 live\u2010born infants, the survival rate for 24 h, 1 week, 1 month and 1 year were 63%, 43%, 33% and 3%. The median survival time was 3.5 days. There was no significant difference between the survival time of <jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>\u2010section and that of vaginal delivery. However, for the births involving breech presentation, the survival time of <jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>\u2010section was significantly longer than that of vaginal delivery. When the fetus is diagnosed with trisomy 18, the parents have to make many choices. These findings constitute critical information in prenatal counseling to the couples whose fetuses have been found to have trisomy 18, especially when they choose palliative approaches in the perinatal management.<\/jats:p>","DOI":"10.1111\/cga.12118","type":"journal-article","created":{"date-parts":[[2015,6,24]],"date-time":"2015-06-24T10:05:15Z","timestamp":1435140315000},"page":"35-40","source":"Crossref","is-referenced-by-count":17,"title":["Fetal
