Can we measure the spiral and uterine artery blood flow by real-time sonography and Doppler indices to predict spontaneous miscarriage in a normal-risk population?

摘要: Introduction: The predictive value of spiral artery flow Doppler measurements a subsequent early miscarriage in first trimester pregnancy is explored here. Objective: aim this study to determine uterine and blood changes miscarriages correlate within the mechanisms indicies. Study design: pulsatility resistance indexes, systolic diastolic ratios, acceleration times, both right left arteries were obtained by trans vaginal color ultrasonography consecutive viable pregnancies between 5 12 gestational week. Women subsequently classified as having continuing or loss before 20 weeks gestation. To predict loss, findings adjusted for maternal age, history previous abortion, presence subchorionic hematoma, embryonic bradycardia, age means multivariate logistic regression analysis. cut-off values are used ROC curve. Results: Twenty-five (11.7%) spontaneously aborted age. In 29 (13.6%) cases there previously abortion history, 30 (14%) had 37 (17.3%) subchoronic hematoma. Regarding parameters resistive index, time, systolic/diastolic ratios flows, only S/D low significantly associated with analysis (P = 0.0001,95% CI: 4.968-55.675). Conclusion: have seem be useful marker. On other hand, could so local that they cannot determined spectral techniques. This suggests vascular bed alterations should measured understand prognosis during trimester.
