Clinical significance of early (<20 weeks) vs. late (20-24 weeks) detection of sonographic short cervix in asymptomatic women in the mid-trimester.

The article presents a cohort study that determine whether the risk of early spontaneous preterm delivery (PTD) in asymptomatic women with a sonographic cervical length of less than equal to 15 mm in the mid-trimester alters as a function of gestational age at diagnosis. It states that the study population comprise of 109 asymptomatic patients. The study finds that asymptomatic women have a dramatic and significantly higher risk of early preterm delivery than women diagnosed at 20-24 weeks.
