At least one half of first trimester pregnancy losses are caused by chromosomal abnormalities.12 Results from chorionic villus sampling suggest that this type of abnormality causes up to 85 percent of all miscarriages.8 Less common causes of first trimester loss include maternal illness, luteal phase defect and other hormonal problems (e.g., polycystic ovary syndrome), and intrauterine adhesions.8, The incidence of disorders associated with third trimester pregnancy losses varies greatly from study to study because of differences in the populations surveyed. Samadi R, 1987;30:352–61. I have two friends who also had a previous cone biopsy and neither of them had a straight-forward delivery. Homer HA, Female genital anomalies affecting reproduction.

Major uterine anomalies have traditionally been associated with second trimester pregnancy loss.13–15 One case-control study showed a significant association between some müllerian duct anomalies and second trimester loss, as well as low birth weight, breech presentation, and maternal hemorrhage.16 The role of surgical correction of these anomalies is controversial, with most studies showing no difference in fetal survival rates with surgical correction compared with uncorrected anomalies. Carquin JS, Gaillard DA, Many patients must also cope with their emotional responses during a subsequent pregnancy. Both remove most or all of the cervix -- a lot more than with a cone biopsy. Cochrane Database Syst Rev. The diagnosis suggested by history and physical examination can be confirmed with hysterography or transvaginal ultrasonography.8,20 The most recent reviews of randomized trials, as well as a report from the American College of Obstetricians and Gynecologists, conclude that there is insufficient evidence to recommend cerclage for a shortened cervix detected by ultrasonography.21–23 There is better support for cervical cerclage in women with three or more second trimester losses or preterm deliveries and cervical change before fetal viability. 21.
