OP11.12: The clinical implications of uterine myomas in preterm delivery; analysis based on antenatal ultrasonographic parameters

Abstract

Oral poster abstractscompared between patients who delivered preterm with those who delivered at term. Statistical analysis was performed with SPSS package. Multiple logistic regression analysis was performed in order to identify the independent risk factors for preterm delivery. Results: A total of 87 women were enrolled in the study group; 26 patients (30.2%) had preterm delivery. When comparing patients who delivered preterm with those delivered at term, no differences were found in maternal characteristics (maternal age, parity, BMI and smoking) between the groups. The cerclage rate was not statistically significant between the groups (3.3% vs.3.8%, p = 0.905). Cesarean section rate was statistically significant higher among the PTD group (20.8% vs. 73.9%, p < 0.001). Cervical length ≤ 25 mm was to be independent risk factors for preterm delivery with OR-9.7, 95% CI 1.57-60, P = 0.014 (Table). Conclusion: Cervical length ≤ 25 mm among patients with vaginal bleeding at 22-34 weeks, is an independent risk factor for preterm delivery. Objectives: To assess the utility of ultrasound cervical length in the prediction of spontaneous onset of labor Methods: 125 women were attended a dedicated post-dates clinic at 41 + 3 weeks of pregnancy and agreed to the assessment of cervical length using transvaginal ultrasound. Those women who had not delivered at 42 weeks, were offered induction of labor. The labor details were prospectively recorded and the mode of delivery was correlated with the ultrasound cervical length data. Results: Women who went into spontaneous labor (n = 75) had a significantly shorter cervical length (p < 0.001) as compared to women whose labor had to be induced (n = 50). Logistic regression analysis showed that cervical length was an independent predictor for the likelihood of spontaneous labor (p = 0.008) and vaginal delivery (p = 0.018). Conclusion:Ultrasound cervical length is a significant independent predictor of likelihood of onset of spontaneous labor and successful vaginal delivery in prolonged pregnancy. OP11.12The clinical implications of uterine myomas in preterm delivery; analysis based on antenatal ultrasonographic parameters group of women without uterine myomas was selected at random for the same period. Excluding preterm delivery prompted by obstetric indications, only the spontaneous preterm delivery (less than 37 weeks of gestation) was included for analysis. Uterine myomas were evaluated for the location, size (largest diameter) and number. The incidence of spontaneous preterm delivery in the study group was compared with that in the control group. Results: The incidence of preterm delivery was significantly higher in patients with uterine myomas compared with in controls (10/102 (9.8%) vs. 13/435 (3.0%), P < 0.05). Regarding the location of uterine myomas, patients with myomas in fundus or corpus of the uterus showed a significantly higher incidence of preterm delivery (10/89 (11.2%) vs. 13/435 (3.0%), P < 0.05). All patients with myomas in the lower segment of the uterus deli...
