The purpose of the application of color Doppler missed abortion and normal early pregnancy in the uterine artery , arcuate artery , radiological artery , spiral artery hemodynamic parameters (systolic / diastolic Moliu speed ratio , resistive index , pulsatility index peak systolic velocity and end-diastolic comparative analysis on the changes in flow rate) , to discover What are differences between the two groups . Line color Doppler examination of the 30 cases expired abortion patients and 30 normal early pregnancy pregnant women were measured uterine artery , arcuate artery radiation artery spiral artery hemodynamic parameters , five blood flow , kinetic parameters respectively measurements: systolic / the diastolic Moliu speed ratio , resistance index , pulsatility index , peak systolic velocity , end-diastolic velocity) . Results missed abortion and normal early pregnancy in uterine artery resistance index , pulsatility index differences , P lt ; 0.05 as statistically significant , missed abortion resistance index higher than early pregnancy . Early pregnancy in the uterine artery measured average RI was 0.85 ± 0.05 , missed abortion in the mean RI of the uterine artery measured 0.79 ± 0.06 . After statistical analysis, missed abortion and normal early pregnancy in uterine artery resistance index , pulsatility index there was significant difference , P lt ; 0.05 as statistically significant , missed abortion and normal early pregnancy in spiral artery resistance index , pulsatility index statistics exist learning differences , P lt ; 0.05 as statistically poor. PSV, EDV, S / D values ??, however , there was no statistical difference in the two groups . Conclusion Color Doppler monitoring of uterine artery hemodynamic parameters to distinguish between missed abortion and normal early pregnancy meaningful . Its advantage is that it can potentially predict pregnancy may fail , for further processing and treatment for the individual patient into a research benefits .
