目的:探讨异位妊娠子宫血循环的特征性改变,提高异位妊娠的诊断率。方法:应用阴道彩超检测56例未破型宫外孕的子宫动脉、螺旋动脉和滋养层动脉血流阻力指数(R I)值,并与60例宫内早孕作对照分析。结果:异位妊娠组子宫动脉平均R I值高于宫内早孕组(P<0.01)。异位妊娠组子宫螺旋动脉彩色多普勒的阳性率则明显低于宫内早孕组(P<0.01);异位妊娠组附件区滋养动脉检出率为95%,特异性100%。结论:经阴道彩色多普勒超声结合临床资料可早期确诊异位妊娠或宫内妊娠。
Objective: To investigate the characteristic changes of uterine blood circulation in ectopic pregnancy and improve the diagnosis rate of ectopic pregnancy. Methods: The blood flow resistance index (R I) of uterine artery, spiral arteries and trophoblasts in 56 cases of unruptured ectopic pregnancy were detected by vaginal color Doppler and compared with 60 cases of early pregnancy in utero. Results: The average R I of uterine artery in ectopic pregnancy group was higher than that in intrauterine pregnancy group (P <0.01). The positive rate of color Doppler in uterine spiral artery of ectopic pregnancy group was significantly lower than that of intrauterine pregnancy group (P <0.01). The detection rate of nodular artery was 95% and the specificity was 100% in ectopic pregnancy group. Conclusion: Transvaginal color Doppler ultrasound combined with clinical data can be early diagnosis of ectopic pregnancy or intrauterine pregnancy.
