动态观察阴道超声对异位妊娠早期诊断的前瞻性研究

open access: yesZhongguo shiyan zhenduanxue, 2002
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 采用HPImagePoint多特色超声系统 ,探头频率 7.5MHz。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  15 5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 80例 ,占 5 1.6 % ,宫内妊娠 75例 ,占 4 8.4 %。异位妊娠诊断率初次检查82 .5 % ,二次检查 94 .0 %
