Cervical length in pregnancy

Mohamed Kandil, Zakaria Sanad, Tarek Sayyed, Hamed Ellakwa
In this prospective cohort study, one hundred participants were allocated into four groups according to their body mass indices. Vaginal ultrasound was performed at enrolment to measure cervical length. The shortest cervical measurement was recorded. Overweight and obese groups had significantly longer mean cervical length than women in the normal weight group when measured at 20-22 weeks of gestation (p < .001). Underweight women had the shortest mean cervical length. The incidence of preterm delivery was the highest in underweight women (RR; 1...

BACKGROUND: There is a lack of consensus on the optimal transvaginal cervical length (TVCL) for determining risk for spontaneous preterm (SPTB) in twin pregnancies. Change in TVCL over time may reflect early activation of the parturition process, as has been demonstrated in singleton pregnancies. The association between change in TVCL and the risk for SPTB has not yet been described in the population of women with diamniotic twin pregnancies. OBJECTIVES: Our primary objective is to determine whether rate of change in TVCL in the midtrimester is associated with SPTB in twin gestations...

INTRODUCTION: Inflammation might be an important underlying cause of preterm birth. Our aim is to explore whether vaginal administration α-lipoic acid reduces cervical inflammation and shortening after primary tocolysis. Matherials and Methods: Singleton pregnancies between 24-30 weeks remaining undelivered after hospitalization for preterm labor were randomly allocated to placebo (20 women, 15 analyzed) or vaginal ALA 400 mg daily (20 women, 17 analyzed) for 30 days. A cervical swab to quantify pro-inflammatory (IL1, IL2, IL6, IL8, TNFα) and anti-inflammatory (IL4, IL10) cytokines as well as transvaginal ultrasound cervical length measurement (CL) were performed before and after treatment...

We present a rare case of a complication after pessary insertion during pregnancy due to short cervix. A woman in the 35th week of gestation was admitted to the Department of Perinatology due to preterm labor. The patient's history revealed cervical pessary insertion during the 29th week of pregnancy due to a cervix of 18 mm in length. Because of threatened preterm labor, the pessary was removed. After pessary removal, a rupture of the cervix was diagnosed. Because of active labor and cervical rupture, a cesarean section was performed and a healthy newborn was delivered...

PURPOSE OF REVIEW: Placental implantation abnormalities (PIAs) comprise a large group of disorders associated with significant maternal, fetal, and neonatal morbidity. RECENT FINDINGS: Risk factors include prior uterine surgery/myometrial scarring and the presence of placenta previa with or without prior cesarean delivery. Newly identified risk factors include previous prelabor cesarean delivery and previous postpartum hemorrhage. PIAs contribute substantially to preterm birth with prematurity rates ranging from 38 to 82%...

Preterm birth, the leading cause of death in children under 5 years, may be caused by inflammation triggered by ascending vaginal infection. About 2 million cervical cerclages are performed annually to prevent preterm birth. The procedure is thought to provide structural support and maintain the endocervical mucus plug as a barrier to ascending infection. Two types of suture material are used for cerclage: monofilament or multifilament braided. Braided sutures are most frequently used, although no evidence exists to favor them over monofilament sutures...
