目的:探讨剪切波弹性成像(SWE)预测疤痕子宫再次妊娠分娩方式的可行性.方法:选取2021年8月—2023年10月于郓城县人民医院进行产前检查的 70 例疤痕子宫再次妊娠产妇为研究对象,均实施SWE检查,总结产妇的疤痕分级、子宫下段厚度、弹性评分及分娩方式.结果:Ⅱ、Ⅲ、Ⅳ级疤痕产妇子宫下段厚度(1.89±0.24)mm小于Ⅰ级疤痕产妇的(4.50±0.31)mm,差异有统计学意义(P＜0.001);Ⅰ级疤痕产妇阴道分娩率29.63%高于Ⅱ、Ⅲ、Ⅳ级疤痕产妇的6.25%,剖宫产分娩率70.37%低于Ⅱ、Ⅲ、Ⅳ级疤痕产妇的 93.75%,差异有统计学意义(P＜0.001);弹性评分 1 分产妇阴道分娩率 43.75%高于弹性评分 2、3 分产妇的 7.89%,剖宫产分娩率 56.25%低于弹性评分 2、3 分产妇的 92.11%,差异有统计学意义(P＜0.001).结论:SWE可通过疤痕分级、厚度测量、弹性评分等预测疤痕子宫再次妊娠产妇的分娩方式.
Abstract
Objective To investigate the feasibility of shear wave elastography(SWE)in predicting the delivery mode of scar uterus re-pregnancy.Methods 70 pregnant women with scarred uterus who underwent prenatal examinations at Yuncheng County People's Hospital from August 2021 to October 2023 were selected as the research subjects and implement SWE examination,and the scar grade,lower uterine thickness,elastic score and delivery mode were summarized.Results The thickness of lower uterine segment in grade Ⅱ,Ⅲ and Ⅳ scar pregnant women(1.89±0.24)mm was significantly smaller than that in grade Ⅰ scar pregnant women,which was(4.50±0.31)mm,and the difference was statistically significant(P＜0.001).The vaginal delivery rate of grade Ⅰ scar pregnant women(29.63%)was significantly higher than that of grade Ⅱ,Ⅲ,Ⅳ scar pregnant women(6.25%),and the cesarean section delivery rate(70.37%)was significantly lower than that in grade Ⅱ,Ⅲ,Ⅳ scar pregnant women(93.75%),and the difference was statistically significant(P＜0.001).The vaginal delivery rate in elastic score 1 pregnant women(43.75%)was significantly higher than that in elastic score 2 and 3 pregnant women(7.89%),and the cesarean section delivery rate(56.25%)was significantly lower than that in elastic score 2 and 3 pregnant women(92.11%),and the difference was statistically significant(P＜0.001).Conclusion SWE can predict the delivery mode of pregnant women with second pregnancy of scarred uterus by scar grading,thickness measurement and elasticity score.
