经腹部和经阴道联合超声检查对早孕期子宫疤痕妊娠的影像学特征和临床价值分析

Analysis of Imaging Characteristics and Clinical Value of Transabdominal and Transvaginal Ultrasonography in Early Pregnancy with Uterine Scar

目的:探讨经腹部和经阴道联合超声检查对孕早期子宫疤痕妊娠(CSP)的诊断价值和临床体会。方法:选择疑诊为早孕期CSP孕妇56例进行经腹部和经阴道彩色多普勒超声检查,将联合检查列入观察组,单纯经腹部检查列入对照组,分析影像学特征并总结临床体会。结果:56例疑诊为早孕期CSP的孕妇中,单纯妊娠囊型31例、混合包块型16例、部分位于宫腔型9例;观察组的单纯妊娠囊型、混合包块型和宫腔型诊断符合率均高于对照组(P<0.05)。观察组的诊断符合率为98.21%,高于对照组的85.71%,误诊率和漏诊率低于对照组(P<0.05);观察组的诊断灵敏度、特异度和阳性预测值均高于对照组(P<0.05)。结论:经腹部和经阴道联合超声检查对早孕期CSP孕妇诊断效能和临床价值较高。

Objective:To explore the diagnostic value and clinical experience of combined abdominal and transvaginal ultrasonography in the early pregnancy with uterine scar pregnancy(CSP).Methods:56 pregnant women suspected to be CSP in early pregnancy were selected for abdominal and transvaginal color Doppler ultrasound examination.Combined examination was included in the observation group,and abdominal examination alone was included in the control group.Imaging features were analyzed and clinical experience was summarized.Results:Among the 56 pregnant women suspected to be CSP in early pregnancy,31 cases were cyst type,16 cases were mixed mass type,and 9 cases were partially uterine type.The diagnosis coincidence rate of simple pregnancy sac type,mixed mass type and uterine type in observation group was higher than that in control group(P<0.05).The diagnosis coincidence rate of observation group was 98.21%,higher than that of control group(85.71%),and the rate of misdiagnosis and missed diagnosis was lower than that of control group(P<0.05).The diagnostic sensitivity,specificity and positive predictive value of observation group were higher than those of control group(P<0.05).Conclusion:The combined abdominal and transvaginal ultrasonography has high diagnostic efficacy and clinical value for CSP in early pregnancy.
