The purpose of this exhibit is: 1: To illustrate cervical measurement by transabdominal and transvaginal ultrasound, show pitfalls that may compromise measurement and provide an algorithm for referal. 2: To demonstrate findings in the "dynamic" cervix. 3: To illustrate cervical cerclage and show how to report cervical length post cerclage.   

Anatomy: Cervical tissue, plicae palmitae, internal os, external os, vaginal fornix, bladder neck, cerclage appearance Imaging modalities: Transabdominal, transperineal, transvaginal ultrasound. Elastography.  Measurement technique:  Pitfalls: Poor technique (resolution, transducer pressure, incorrect measurement, failure to demonstrate dynamic change) Nabothian cyst Gartner duct remnants Mullerian duct anomalies Fibroids Post operative cervix (LEEP, septal resection, trachelectomy) Importance: The preterm birth rate in the US is >12% with resulting neonatal morbidity and mortality. A shortened mid-trimester cervical length is one of the most consistent and significant risk factors. Interventions including vaginal progesterone and cervical cerclage have been shown to reduce the risk of spontaneous PTB. Thus, it is imperative that cervical insufficiency be recognized and appropriately addressed
