Role of cervical length measured on transvaginal ultrasound at 19-24 weeks in prediction of preterm labor

Abstract

Aim: The aim of the present study was to assess the role of cervical length measured on transvaginal ultrasound at 19-24 weeks in prediction of preterm labor. Methods: The present study was conducted in the Department of Radio-Diagnosis, Bapuji Hospital, JJM Medical College, Davanagere and pregnant women between 19-24 weeks of gestation were included. 150 pregnant women visiting the Ultrasonography clinic at Bapuji Hospital, JJM Medical College, Davanagere were included. The study was conducted over a period of 1.5 year. Results: 107 (71.3%) patients had 21 to 25 years of age, 22 (14.7%) patients had 26 to 30 years of age, 18 (12.0%) patients had 31 to 35 years of age and 3 (2.0%) patients had 36 to 40 years of age. 84 (56.0%) patients were Multiparous and 66 (44.0%) patients were Nulliparous. 11(7.3%) patients had ≤20mm cervical length, 22(14.7%) patients had 21 to 30mm cervical length, 36mm (24.0%) patients had 31 to 40 mm cervical length and 81(54.0%) patients had >40mm cervical length. 26 (17.3%) patients had preterm birth and 124 (82.7%) patients had term birth. 44(29.3%) patients had LSCS and 106 (70.7%) patients had VD. Association of age in years vs. cervical length was not statistically significant (p=0.3090). Association of preterm / term labor vs. cervical length was statistically significant (p
