Sonographic Evaluation of Cervical Length Changes During Normal Pregnancy (Original Work) (Report)

INTRODUCTION Sonographic evaluation of the gravid cervix is important for the assessment of cervical incompetence, preterm labor and placenta previa (1-12). Premature delivery affects 7% to 11% of all newborn infants and remains a major cause of perinatal morbidity and mortality. Despite the increasingly varied choice of therapies and treatments available to present day obstetricians for the management of pregnancy, no significant changes have been reported so far in preterm birth (PTB) rates, which of course, vary widely among different populations studied because of racial, social, economic, and environmental factors. The proportion of women at risk of PTB is about 7% in France and 8% to 9% in Italy (13). In the United States, where the rate has been unchanged for the last 3 decades, the PTB rate is 10% to 11% (14).
