目的探讨超声测量中晚期子宫瘢痕前壁下段厚度对阴道试产及先兆子宫破裂的临床意义。方法选取2013年8月至2015年7月同济大学附属第一妇婴保健院收治的中晚期子宫瘢痕孕妇136例,采用彩色超声技术观察子宫瘢痕形态及测量前壁下段厚度,根据子宫瘢痕等级分为3组,Ⅰ级瘢痕组84例,Ⅱ级瘢痕组30例,Ⅲ级瘢痕组22例,观察3种子宫瘢痕等级孕妇的妊娠结局。结果 34周、36周、38周、40周Ⅰ级子宫瘢痕孕妇的瘢痕前壁下段厚度(4.39±0.10,4.21±0.14,4.03±0.16,3.26±0.19)均显著高于Ⅱ、Ⅲ级子宫瘢痕的厚度(2.71±0.20,2.15±0.28,2.01±0.35,1.97±0.34),差异有统计学意义(P<0.05);随着孕周的增加,Ⅰ、Ⅱ、Ⅲ级瘢痕前壁下段厚度也逐渐变薄(P<0.05);随着子宫瘢痕等级的增加,孕妇阴道试产成功率逐渐下降,先兆子宫破裂的发生率逐渐升高,差异有统计学意义(P<0.05)。结论超声检测中晚期子宫瘢痕前壁下段厚度,对临床阴道试产及先兆子宫破裂具有一定的指导意义。
Objective To investigate the clinical value of ultrasound in the measurement of the thickness of the anterior wall of uterine scar in the middle and late pregnancy. Methods 136 cases of patients with uterine scar pregnancy treated in First Maternity and Infant Hospital affiliated of Tongji University from August 2013 to July 2015 were selected, color Doppler ultrasound was used to observe the morphology and thickness of the anterior wall of the uterine scar. On the basis of grades of uterine scar, the patients were divided into I （n =84）, II （n =30）, and m （n =20） groups. Compared the pregnancy outcomes of three groups. Results When 34 weeks, 36 weeks, 38 weeks, 40 weeks, the thickness of the anterior wall of uterine scar in Ⅰ grade group were significantly higher than the level of Ⅰ and Ⅲ grade groups. The differences were statistically significant （ P 〈 0.05 ）. With the increase of gestational age, the thickness of Ⅰ , Ⅱ, and Ⅲ grade groups gradually became thinner （ P 〈 0. 05 ）. With the increase of the grades of uterine scar, vaginal trial production success rate decreased gradually and threatened uterine rupture occurred rate increased gradually. The differences were statistically significant （ P 〈 0. 05 ）. Conclusion Detecting the thickness of anterior wall of uterine scar in the middle and late pregnancy has guiding significance in clinical trial of vaginal delivery and threatened uterine rupture.
