Clinical implications of sonographic detection of uterine anomalies for reproductive outcome.
The purpose of this review article was to analyze the literature on the prevalence, diagnosis and treatment of the congenital uterine anomalies and to discuss current dilemmas on their influence on reproductive outcome. Congenital uterine anomalies are commonly associated with repeated pregnancy failure, in particular an increased risk of first- and second-trimester miscarriages and preterm delivery. Recent reports on two-dimensional and three-dimensional transvaginal ultrasound and saline contrast sonohysterography appear promising for diagnosis and classification of congenital uterine anomalies. The ability to visualize both the uterine cavity and the fundal uterine contour on a three-dimensional scan facilitates the diagnosis of uterine anomalies and enables differentiation between septate and bicornuate uteri. Color Doppler ultrasound allows visualization of intraseptal vascularity and may help in distinguishing the avascular from the vascular septum. Less connective tissue in the septum may result in poor decidualization and placentation, while an increased amount of muscle tissue in the septum can cause miscarriage by the production of local uncoordinated myometrial contractility. Hysteroscopic septum excision is an effective procedure which improves live-birth rates. Because of its simplicity, minimal invasiveness, low morbidity and low cost, a more liberal approach to the treatment of uterine anomalies is being advocated.
