目的探讨超声检查应用于输卵管间质部妊娠的诊断中的价值。方法回顾性分析37例输卵管间质部妊娠的超声声像图特征，随访临床术后结果。结果37例输卵管间质部妊娠患者中，超声检查正确诊断31例，准确率约为83.8%；误诊6例，其中宫角部妊娠3例，残角子宫1例，双角子宫伴一侧妊娠1例，滋养细胞疾病1例。间质部妊娠据典型的声像图分为：孕囊型和包块型两种。结论超声检查诊断输卵管间质部妊娠的准确性较高，经阴道超声可提高诊断的准确性。“,”Objective To explore the clinical values of ultrasonography in diagnosis of interstitial tubal pregnancy.Methods A retrospective analysis was made on the Sonographic features of 37 cases of patients with interstitial pregnancy,and followed the results.Results In 37 cases of interstitial tubal pregnancy patients,31 cases were correctly diagnosed by ultrasonography,the accuracy rate of which is 83.8%;6 cases were misdiagnosed, including 3 cases of intrauterine pregnancy,1 cases of residual angle,1 cases of double angle of uterus and cases of gestational age,1 cases of the disease.The typical sonographic features:gestational sac type and mass type.Conclusion Ultrasonography has high accuracy in diagnosis of interstitial pregnancy,and transvaginal sonography can significantly improve the accuracy.
