Cervical length at 23 weeks of gestation: the value of Shirodkar suture for the short cervix

Abstract

In women with a cervical length of < or = 15 mm at 23 weeks there is a more than 50% chance of spontaneous delivery at less than 32 weeks. Insertion of a Shirodkar suture in women with a very short cervix may be associated with a ten-fold reduction in risk for such early delivery.
