Cervical Insufficiency

Excerpt

Cervical insufficiency is the inability of the cervix to retain fetus, in the absence of uterine contractions or labor (painless cervical dilatation), owing to a functional or structural defect. It is cervical ripening that occurs far from the term. Cervical insufficiency is rarely a distinct and well defined clinical entity but only part of a large and more complex spontaneous preterm birth syndrome.
