Two had undergone an intervention to prevent SPB, cervical cerclage
of which one resulted in SPB.
A patient-level meta-analysis published in 2011 demonstrated that cervical cerclage
placement was associated with a significant reduction in preterm birth before 35 weeks' gestation in women with singleton gestations, previous spontaneous preterm birth, and cervical length less than 2.
In general, placement of a cervical cerclage
is not offered past the point of fetal viability, which is generally in the range of 23 to 25 weeks' gestation, depending on local institutional and neonatal intensive care unit policies.
Surgical intervention by cervical cerclage
is the mainstay for treatment of cervical incompetence, using the MacDonald's and Shirodkar methods (7).
Objective: To study the efficacy of cervical cerclage
using McDonald's technique in prevention of preterm deliveries.
Cervical incompetence or short cervix is a risk factor for the condition and cervical cerclage
is the management option for such cases.
6) Even though transvaginal ultrasound assessment of the cervix during pregnancy has been found to be useful in predicting preterm birth in some cases of suspected cervical weakness, (3) treatment of cervical incompetence with cervical cerclage
may not actually result in improved perinatal survival.
Improving the outcome of cervical cerclage
by sonographic follow-up.
Results of the randomized, controlled CIRCLE (Assessment of Cervical Cerclage
for the Prevention of Preterm Labour) trial do not suggest any benefit in replacing historical indications for suture placement with ultrasound surveillance, Dr.
A 30-year-old, 167 cm, 57 kg woman with a twin pregnancy at the 23rd week of gestation was scheduled for cervical cerclage
Specimens were excluded if collected from women who had chemically induced labor or elective caesarian section within 2 weeks of fFN collection, multiple gestation, cervical dilation [less than or equal to] 3 cm, ruptured membranes, cervical cerclage
, moderate or gross vaginal bleeding, placenta previa, or sexual intercourse within 24 h.
The investigators excluded 246 of 740 women who had a positive screening test because of various reasons, including symptomatic bacterial vaginosis; age <16 years; multiple gestations; had or needed cervical cerclage
or cone biopsy; demonstration of a cervical, uterine, or fetal anomaly; diabetes mellitus, hypertension, or collagen vascular disease.
