Title

Cervical gland area as an ultrasound marker for prediction of preterm delivery: A cohort study

Pages

  729-734

Abstract

 Background: Preterm Labor is a major cause of perinatal morbidity and mortality and it might be predicted by assessing the cervical change. Objective: To assess the association between absence of cervical gland area (CGA) and spontaneous Preterm Labor (SPTL). Materials and Methods: This prospective cohort study was performed on 200 singleton pregnant women with a history of SPTL, second-trimester abortion in the previous pregnancy or lower abdominal pain in current pregnancy. Each patient underwent one transvaginal ultrasound examination between 14-28 wk of gestation. Cervical length was measured and CGA was identified and their relationship with SPTL before 35 and 37 wk gestation was evaluated using STATA software version 10. Results: The mean of cervical length was 36. 5 mm (SD=8. 4), the shortest measurement was 9 mm, and the longest one was 61 mm. Short cervical length (≤ 18mm) was significantly associated with SPTL before 35 and 37 wk gestation. Cervical gland area (the hypoechogenic or echogenic area around the cervical canal) was present in 189 (94. 5%) patients. Absent of CGA had a significant relationship with SPTL before 35 and 37 wk gestation (p=0. 01 and p<0. 001, respectively). Cervical length was shorter in women with absent CGA in comparison with subjects with present CGA: 37± 10 mm in CGA present group and 23± 9 mm in CGA absent group (p<0. 001). Conclusion: Our study showed that cervical gland area might be an important predictor of SPTL which should be confirmed with further researches.
