摘要
目的研究通过超声检测中晚期子宫瘢痕前壁下段厚度在临床中的应用意义。方法 200例中晚期子宫瘢痕孕妇,超声检查子宫瘢痕前壁下段厚度,根据子宫瘢痕分级标准将孕妇分为Ⅰ度组(110例)、Ⅱ度组(64例)和Ⅲ度组(26例)。观察孕34、37、40周3个时期三组瘢痕厚度变化情况,比较三组阴道试产、先兆子宫破裂情况。结果Ⅰ度组孕妇的瘢痕厚度显著高于Ⅱ、Ⅲ度组孕妇,差异具有统计学意义(P<0.05)。同组孕妇随着孕周增加,瘢痕厚度逐渐变薄,差异具有统计学意义(F=3.784、4.635、2.934,P<0.05)。孕妇瘢痕分级越高,孕妇阴道试产成功率越小,发生先兆子宫破裂几率越大,差异具有统计学意义(P<0.05)。结论超声检测孕妇不同时期子宫瘢痕前壁下段的厚度有利于指导发现先兆子宫破裂及其阴道试产。
Objective To research significance by ultrasound detection of moderate and advancedcesarean scar lower segment antetheca thickness in clinical application.Methods A total of200pregnant womenwith moderate and advanced cesarean scar in ultrasound detection of lower segment antetheca thickness weredivided by grading standard of cesarean scar into gradeⅠgroup(110cases),gradeⅡgroup(64cases)and gradeⅢgroup(26cases).Observation was made on scar thickness changes condition,and comparison were made onvaginal trial of labor and threatened uterine rupture condition in the three groups at34,37,40gestational weeks.Results GradeⅠgroup had obviously higher scar thickness than gradeⅡgroup and gradeⅢgroup,and theirdifference had statistical significance(P<0.05).Development of gestational weeks led to decreased scar thicknessin each group,and the difference had statistical significance(F=3.784,4.635,2.934,P<0.05).Higher cesareanscar grade led to lower success rate of vaginal trial of labor and higher incidence of threatened uterine rupture,andthe difference had statistical significance(P<0.05).Conclusion Ultrasound detection of moderate and advancedcesarean scar lower segment antetheca thickness in different time period is helpful for discovery of threateneduterine rupture and related vaginal trial of labor.
