目的:探讨经阴道彩色多普勒超声(简称超声)对输卵管间质部(简称间质部)妊娠的定位及定性诊断价值。方法:对28例经手术病理结果证实的间质部妊娠声像图特征进行分析。结果:28例间质部妊娠病例,超声诊断正确率75.0%(21/28)。根据声像图表现分为三型:即妊娠囊型、包块型、破裂型。妊娠囊型9例,1例误诊为宫角妊娠(8/9);包块型16例,1例误诊为宫角妊娠,2例误诊为滋养细胞疾病(3/16);破裂型3例,均诊断为宫外孕破裂出血,未明确定位诊断。结论:超声对间质部妊娠的诊断及鉴别诊断具有重要的临床应用价值。
Objective: To investigate the value of transvaginal color Doppler ultrasound (referred to as ultrasound) in the localization and qualitative diagnosis of tubal interstitial (referred to as interstitial part) pregnancy. Methods: 28 cases of pathological findings confirmed by the Department of interstitial pregnancy ultrasound features of the image were analyzed. Results: In 28 cases of interstitial pregnancy, the correct rate of ultrasound diagnosis was 75.0% (21/28). According to the performance of the sonogram is divided into three types: the gestational sac type, mass type, rupture type. 9 cases of gestational cysts, 1 case misdiagnosed as uterine horn pregnancy (8/9); mass in 16 cases, 1 case misdiagnosed as uterine horn pregnancy, 2 cases misdiagnosed as trophoblastic disease (3/16); rupture in 3 cases , Were diagnosed as ectopic pregnancy rupture bleeding, not clear diagnosis. Conclusion: Ultrasound has important clinical value in the diagnosis and differential diagnosis of interstitial pregnancy.
