Abstract

Objective: To describe the clinical and para-clinical characteristics of pregnant women at risk of preterm birth with a short cervix (<25mm) at Hanoi Obstetrics and Gynecology Hospital. Subjects and Methods: A prospective longitudinal study was conducted on 70 pregnant women at risk of preterm birth who were treated at Hanoi Obstetrics and Gynecology Hospital and had a cervical length of less than 25mm. Gestational age ranged from 22 weeks 0 days to 34 weeks 0 days. The study period was from August 2024 to August 2025. Results: The average maternal age was 29.1 ± 4.9 years, with the most common age group being 20–29 years (48 out of 70 participants). Most participants resided in Hanoi (43 cases, 61.4%). Common occupations included office administration (23 cases) and freelance labor (24 cases). There was no significant difference in average weight among cervical length subgroups (p = 0.712). More than one-third of participants had comorbidities (35.7%), with gestational diabetes mellitus (GDM) being the most common (16%). A high proportion had a history of late miscarriage or preterm birth (26%). Nine participants had a history of cervical cerclage in previous pregnancies (13%). Most pregnancies were conceived naturally (47 cases, 67.1%) and were singleton pregnancies (53 cases, 75.7%). Seventeen cases were twin pregnancies, of which 15 were conceived via IVF. The most common cervical shape was Y-shaped (87.1%), while less common shapes included I, V, and U. These differences were statistically significant with 99% confidence. The average cervical length varied significantly among different shapes (p = 0.01 < 0.05, 95% confidence level). Conclusion: A history of late miscarriage and preterm birth is closely associated with the risk of threatened preterm labor and short cervix. Cervical morphology is diverse, with cervical length decreasing in the following order: I-shape > Y-shape > V-shape > U-shape.
