Fetal Survival Following Threatened Abortion

The Outcome of Pregnancies Complicated by Threatened Abortion

“…Our study confirmed previous reports [1][2][3][4][5][6][7] that the greatest risk to pregnancy complicated by vaginal bleeding before 20 weeks is preterm delivery. Weight and gestational age at birth are the most important determinants of an infant's survival, as well as healthy growth and development [11].…”

“…1990; 10(6): 593-597 Threatened abortion complicating early pregnancy is known to be associated with suboptimal pregnancy outcome. Many studies have shown an increase in the risk of preterm delivery [1][2][3][4][5][6][7], low birth weight [2][3][4][5]8], and small-for-gestational-age infants [2][3][4][5], as well as increased perinatal mortality [2][3][4]6,7,9], though a more recent study failed to show this increase [5]. Other complications were also shown to be increased, including congenital anomalies [9,10], abruptio placentae [4], malpresentations [2], and retention of placenta [5],…”

Alpha‐fetoprotein, vaginal bleeding and pregnancy risk

“…With or without bleeding, however, higher MSAFP levels are associated with increased risk, in some cases even while MSAFP is still within the normal range. The frequency of vaginal bleeding (8.6%) in our population is similar to that found in another recent report (Batzofin et al 1984), and the relative risk for fetal morbidity and mortality in the presence of vaginal bleeding is also consistent with published reports (Turnbull & Walker 1956;Thompson & Lein 1961;Peckham 1970;Niswander & Gordon 1972;Fedrick & Anderson 1976;Fedrick & Adelstein 1978;Funderbunk et al 1980;Batzofin et al 1984). Nearly all of the fetal deaths in women with MSAFP elevations occur within 6 weeks, regardless of bleeding.…”

“…1977~;Lidbjork et al 1977). Vaginal bleeding, by itself, is a risk factor for a variety of pregnancy complications (Turnbull & Walker 1956;Thompson & Lein 1961;Peckham 1970;Niswander & Gordon 1972;Fedrick & Anderson 1976;Fedrick & Adelstein 1978;Funderbunk et al 1980;Batzofin et al 1984). The present study was designed to assess the value of combining knowledge about vaginal bleeding with MSAFP measurement to determine risk of fetal morbidity and mortality.…”
