Article Abstract
Objectives: The aims of this study were to clarify the following: (1) how often does prolonged pregnancy ≥34 weeks occur in patients with emergent cerclage without progesterone and (2) the risk factors preventing such pregnancy continuation.
Materials And Methods: This retrospective observational study was performed using medical records of patients for whom emergent cerclage had been performed between April 2006 and December 2018 in our institute.
Results: Emergent cerclage was performed in 123 patients (median age: 34, interquartile range: 31-36). Primiparous patients numbered 44 (36%). A history of spontaneous preterm birth (SPTB) was present in 30 (24%). The median presurgical cervical length (CL) was 16 (8-21) mm at surgery. Of the 123, 20 (16%) were delivered at 33 + 6 weeks or less (<34 weeks). We conducted logistic regression analysis of the risk factors of SPTBs <34 weeks after cerclage. Three risk factors were identified that increased the risk of SPTB <34 weeks: presurgical CL 0 mm (odds ratio (OR): 5.30; 95% confidence interval (CI): 1.58-17.7), a history of SPTB (OR: 4.65; 95% CI: 1.38-15.7), and the presence of sludge (OR: 4.14; 95% CI: 1.20-14.3).
Conclusion: Three risk factors predicted SPTB <34 weeks after emergency cerclage without progesterone administration: unmeasurable CL (CL 0 mm), a history of SPTB, and the presence of sludge on ultrasound. SPTB <34 weeks occurred after emergency cerclage in 16% of patients, being comparable with the recent data with progesterone.

Introduction: Uterine fibroids are a common cause of infertility, and myomectomy remains a key surgical intervention to improve reproductive outcomes. However, the occurrence of an undetected pregnancy during myomectomy is rare and poses significant clinical risks.
Case Presentation: We report a 34-year-old woman, nulliparous with a history of secondary infertility and three first-trimester miscarriages.

Background: Preterm birth is the leading cause of neonatal mortality and long-term health complications. Cervical cerclage (CC) represents a critical intervention for extending pregnancy duration and enhancing neonatal survival in patients diagnosed with cervical insufficiency. The aim of this study was to identify risk factors for preterm birth through a meta-analysis comparing outcomes between preterm and full-term deliveries following non-emergency CC.

Surgical outcomes, fracture healing, pain relief, functional recovery, and complication rates were compared with intramedullary nailing alone.
Methods: A retrospective cohort study was conducted on patients diagnosed with Seinsheimer III subtrochanteric fractures who underwent either intramedullary nailing alone (control group) or intramedullary nailing with steel cable cerclage (observation group).

Objective: To evaluate the efficacy of cervical cerclage in preventing preterm birth (PTB) in asymptomatic singleton pregnancies without prior spontaneous PTB and with a mid-trimester short transvaginal ultrasound cervical length (TVU CL).

Introduction: Cervical insufficiency (CI) is a significant cause of late miscarriage and preterm birth (PTB) before 27 weeks. In the presence of cervical dilation without associated symptoms, between 14 and 24 weeks, performing an emergent cerclage has shown effectiveness in prolonging pregnancy and improving neonatal outcomes. The aim of this study was to evaluate the obstetric and neonatal outcomes of pregnancies complicated by cervical insufficiency requiring emergent cerclage placement.
