It requires a sagittal view of the cervix, with the cervix occupying 50-75% of the screen and the cervical canal, internal os and external os visible. Role of cervical pessary in women with previous spontaneousPTBand short cervix According to a 2020 systematic review and meta-analysis, current evidence does not support use of cervical pessary to prevent PTB in women with singleton gestation and TVS CL <= 25 mm before 24 weeks, irrespective of previous obstetric history ( I P i = 0.24), concomitant use of vaginal progesterone ( I P i = 0.70) or severity of CL shortness ( I P i = 0.68)72. However, the accuracy of CL measurement to predict PTB depends on various factors, such as the population studied, its baseline PTB prevalence, the cut-off values for defining short cervix and PTB, the gestational age at which the screening test is performed, and the compliance of healthcare providers and patients with the preventive strategy that is applied after a high-risk result. Similarly, the QUiPP app v.2 algorithms developed and validated for the prediction of PTB in women with symptoms of threatened PTL demonstrated good accuracy, with AUCs of 0.96 for PTB < 30 weeks, 0.85 for PTB < 34 weeks, 0.77 for PTB < 37 weeks, 0.91 for PTB < 1 week from testing and 0.92 for PTB < 2 weeks from testing183. Management options after identifying short cervix in asymptomatic singleton pregnancy The main objective of measuring CL in low-risk pregnant women is to make a targeted selection of the patients with a short cervix and therefore a higher risk of PTB, in order to initiate preventive intervention in a timely fashion (secondary prevention).
