Outcome of pregnancy after threatened abortion.

ABSTRACT

In a prospective study of 203 pregnancies complicated by threatened abortion, obstetrical and neonatal data were analysed for pregnancy outcome. Comparison was made with a selected group of 496 non-risk pregnancies. There was a high incidence of pre-term birth, low birth weight infants and antepartum haemorrhage. The incidences of perinatal mortality and congenital malformations did not differ significantly from those of the control group. These findings suggest that early gestational virginal bleeding is one predictor of suboptimal pregnancy outcome.
