A longitudinal study about the correlation of cervical length and preterm delivery / 中国医师杂志

Objective To investigate the correlation between cervical length and preterm birth rate in pregnant women with cervical shortening.Methods A group of pregnant women who had had two children in our hospital were included.Both lengths of 24-28 weeks were measured by transvaginal ultrasound during both pregnancies.According to the length of the cervix measured by the vagina during the first trimester and whether it is full-term production,it can be divided into the cervical shortening full-term group,the cervical shortening premature delivery group,the normal cervical full-term group (control group),and the clinical and ultrasound measurements are statistically analyzed.Results The cervical shortening in the preterm group and the cervical shortening in the full-term group were more likely to have cervical reduction in the second pregnancy than in the normal cervical full-term group (P ＜ 0.05).The rate of spontaneous preterm birth in the second trimester of the cervix shortened in the preterm group was the highest (P ＜ 0.05).There was no significant difference in the preterm birth rate of the second pregnancy between the normal uterine cervix group and the cervical shortened term group (P ＞ 0.05).Conclusions In the pregnant women with cervical shortening,cervix shortening occurs.Whether the first child is full-term is the key factor in predicting the second premature birth rate.

Radiologic Findings of Cervical Varix Developed in Late Pregnancy: Case Report

Cervical varix is a rare cause of obstetric hemorrhage which needs accurate diagnosis and prompt management because the lesion may be associated with preterm delivery and maternal complications. Our patient was diagnosed with cervical varix and vaginal bleeding at 32 weeks' gestation, using transvaginal ultrasound and MRI. Persistent vaginal bleeding and preterm labor led to an emergency cesarean section at 33 weeks'gestation. After delivery, cervical varix was spontaneously resolved in the follow-up transvaginal ultrasound and CT. We report various radiologic features of cervical varix combined with vaginal bleeding in late pregnancy.
