【摘要】：目的比较妊娠中期和晚期经阴道超声检测子宫瘢痕前壁下段厚度对评估分娩方式及预测妊娠结局的价值。方法选取该院收治的剖宫产术后再次妊娠的154例患者,采用经阴道超声分别于孕28周和孕36周时测量子宫瘢痕前壁下段厚度,比较孕28周和孕36周时子宫瘢痕前壁下段厚度对患者分娩方式及子宫破裂发生情况的预测价值。结果孕36周时子宫瘢痕前壁下段厚度明显较28周时下降(P0.05),选择再次剖宫产的孕妇子宫瘢痕前壁下段厚度在孕中、晚期均显著低于经阴道分娩孕妇,差异有统计学意义(P0.05)。11例发生子宫撕裂孕妇的前壁下段厚度显著低于未发生子宫撕裂孕妇(P0.05)。孕36周时,11例中有10例患者子宫瘢痕厚度小于2 mm,孕28周时有3例发生子宫撕裂的孕妇前壁下段厚度大于平均值。结论经阴道超声检测子宫瘢痕前壁下段厚度有利于评估分娩方式及预测子宫破裂风险,孕28周时的结果具有一定指导意义。
[Abstract]:Objective to compare the value of transvaginal ultrasonography in evaluating the delivery mode and predicting the outcome of pregnancy by transvaginal ultrasound in detecting the thickness of the anterior wall of uterine scar in the second and third trimester of pregnancy. Methods 154 cases of pregnancy after cesarean section were selected. The thickness of anterior wall of uterine scar was measured by transvaginal ultrasound at 28 weeks and 36 weeks of pregnancy, respectively. To compare the predictive value of the thickness of anterior wall of uterine scar between 28 weeks and 36 weeks of pregnancy on the mode of delivery and the occurrence of uterine rupture. Results at 36 weeks of pregnancy, the thickness of the anterior wall of uterine scar was significantly lower than that of 28 weeks of gestation (P 0.05). The thickness of the lower segment of the anterior wall of uterine scar in the second cesarean section was significantly lower in the third trimester than that in the vaginal delivery. The thickness of anterior wall of 11 pregnant women with uterine tears was significantly lower than that of pregnant women without uterine tears (P 0.05). The thickness of uterine scar was less than 2 mm in 10 out of 11 cases at 36 weeks of gestation, and the thickness of anterior wall in 3 cases with uterine tear was greater than the average at 28 weeks of gestation. Conclusion Transvaginal ultrasound examination of the thickness of the anterior wall of uterine scar is helpful to evaluate the mode of delivery and predict the risk of uterine rupture, and the results at 28 weeks of pregnancy have certain guiding significance.
