摘要
目的:通过阴道超声检查临床疑诊异位妊娠患者,进行动态观察对异位妊娠早期诊断的前瞻性研究。方法:应用阴道超声反复多次检查,参照异位妊娠阴道超声诊断标准,结合手术对照,比较阴道超声单次检查与多次检查对异位妊娠早期诊断的准确性。结果:200例临床疑诊异位妊娠经过阴道超声反复多次检查,异位妊娠103例,占52.5%,宫内妊娠97例,占47.5%。异位妊娠诊断率初次检查80.5%,2次检查93.3%,3次检查98.0%。异位妊娠假阳性2例(初次检查诊断),假阳性率1.9%。结论:阴道超声较腹部超声能较早地确定宫内妊娠和发现异位妊娠;反复多次检查较单次检查对异位妊娠的早期诊断准确性有较大的提高;动态观察可降低异位妊娠的假阳性率。
Objective： To study prospectively serial transvaginal sonography for early diagnosis of ectopic pregnancy through examining the patients with clinically suspected diagnosis of ectopic pregnancy. Methods： The patients underwent repeated examinations. The accuracy of diagnosis from a single examination was compared with that from multiple examinations according to the standards for diagnosis of ectopic pregnancy by transvaglnal ultrasound and the relating findings from operations. Results： Among all 200 cases undergoing multiple transvaginal ultrasound exsminations, 103 cases were ectopic pregnancy （52. 5% ）, 97 cases were intrauterine pregnancy （47. 5% ）. The accuracy of diagnosis of ectopic pregnancy was 80. 5% all the fist examination, 93. 3% at the second time and 98% at the third time. 2 cases were false positive ectopic pregnancy （at the fist examination）, the rate of false positive was 1. 9%. Conclusion： Transvaginal ultrasound is superior to transabdominal sonography all the aspect of early diagnosis in intrauterine and ectopic pregnancy. Serial transvaginal ultrasound demonstration can more greatly improve the accuracy of diagnosis of ectopic pregnancy than a single examination and can reduce the rate of false positive.
