Multiple pregnancy with late death of one fetus.
Twenty cases of fetal death complicating a multiple pregnancy after 20 weeks' gestation are reviewed. We evaluated gestational age at diagnosis and delivery (29.3 +/- 0.7 and 31.8 +/- 0.9 weeks, respectively), interval from diagnosis to delivery (2.6 +/- 0.6 weeks), and cause of fetal death as a group and by type of placentation (76.5% monochorionic). Eighty-five percent of the surviving fetuses were delivered preterm, and the four neonatal deaths were all due to extreme prematurity, with a mean (+/- SEM) birth weight of 794 +/- 237 g. Perinatal mortality was 585 per 1000, 450 for twin A and 750 for twin B. The causes of fetal death varied. Maternal disseminated intravascular coagulation was not diagnosed in any pregnancy in the present series. The high risk of complications related to preterm birth, compared with the low risk of problems related to continuation of a multiple pregnancy after diagnosis of a fetal death, argues in favor of conservative management in this setting.
