Acquired and inherited thrombophilia in women with unexplained fetal losses

Women who have had a miscarriage may have a genetic tendency to create excessive blood clots, according to a study of 150 women. Thirty-five percent of the women who had one or more miscarriages had this condition, compared to 16% of the women who had a full-term pregnancy. This condition could cause blood clots to form in the placenta.
