ReviewUniversal cervical length screening for prediction and prevention of preterm birth.
Universal transvaginal ultrasound (TVU) cervical length (CL) screening represent a step forward in the campaign against preterm birth (PTB). Transvaginal ultrasound CL is a safe, acceptable, reproducible, and accurate screening test, with potentially widespread availability given its feasibility. For this screening to be effective, the ultrasounds should be done with proper TVU technique and with continuing quality assurance. ⋯ Transabdominal CL screening has not been sufficiently studied and cannot be recommended. Results from just 1 trial offer promise for pessary as another effective intervention, which cannot be recommended yet until results are confirmed with another trial. Transvaginal ultrasound CL in multiples cannot be recommended yet, given lack of effective interventions in this population.
