阴道彩色多普勒监测药物引产后宫内残留

Monitoring for Retention of Villi after Drug Induction by Endovaginal Color Dopple

对５８例早孕药物引产后阴道出血不止者、６０例早孕者、３０例正常生育期未孕者的子宫螺旋动脉多普勒血流频谱进行比较分析，与临床随访对照后得出：子宫螺旋动脉的ＲＩ值低于０．５则可判定为药物引产后宫内残留绒毛；而高于０．５５为完全流产后宫腔积血，ＲＩ值在０．５～０．５５之间以宫腔积血为主。故ＲＩ可作为诊断药物引产后宫内残留的参考指标。

We contrasted ad analyted Doppler flow frequency spetrums of uterine spiral arteries among 58 early pregancy with constant vaginal bleeding after drug induction,60 cases of early pregnancy and 30 childbearing age woman without pregnancy. The conclusion obtained after certain period follow-up is that,the RI value of uterine spiral artery is below 0.5 in those with villi residue, above 0.55 in those with blood accumulating in uterine,but value between 0.5 to 0.55 is mainly due to blood accumulating in utreine.Therefore the RI value could be a refernce idex for diagnosis of villi residue after drug induction.
