摘要

背景：在世界各地，双相彩色多普勒超声在评估各种疾病过程中的血管方面越来越受欢迎。在过去的20年里，多普勒超声的技术及其在产科和胎儿医学中的应用都有了巨大的发展。目的：本研究旨在观察先兆子痫患者的多普勒波形。具体目的是观察不同组研究对象在第24-37周的RI和PI，并找出两组之间不同多普勒指数的显著差异（即计算两组中具有舒张早期切迹的受试者的比例）。材料和方法：本研究在达卡医学院医院放射与成像科进行，共纳入40名先兆子痫受试者，为期6个月，从2014年6月20日至2014年12月19日。总共40例正常妊娠也被纳入比较。结果：大多数受访者（35%为正常人，37.5%为先兆子痫）年龄在21-30岁之间。未配对t检验显示两组的平均年龄之间没有显著差异。在正常组中，PI和RI的平均±SD分别为1.12±0.0846和0.571±0.058，在先兆子痫组中，平均PI和RI分别为2.497±0.369和0.8255±0.087。这两组之间的平均多普勒指数存在统计学显著性差异（通过非配对t检验）。90%的先兆子痫受试者和5%的正常妊娠受试者出现早期舒张陷波。卡方检验显示，正常受试者和先兆子痫受试者在舒张早期切迹的存在方面存在统计学上的显著差异。结论：从研究结果可以得出结论，具有舒张早期切迹的多普勒指数是早期检测先兆子痫的可靠指标。《搪瓷医学杂志》2020；10（1）：33-38

Prediction of Preeclampsia in Pregnant Population Using Diastolic Notch of Uterine Artery by Duplex Color Doppler Study

Background: Use of Duplex Color Doppler Sonography is gaining increasing popularity for assessment of blood vessels in various disease processes around the world. The past 20 years have seen an enormous growth in both technical aspects of Doppler ultrasound and its application in obstetric and fetal medicine. Objective: This cross-sectional study was carried out to observe Doppler wave form in subjects with preeclampsia. Specific objective was to see RI and PI in different groups of study subjects from 24th to 37th weeks and find out significant difference of different Doppler indices between two groups (i.e., to calculate the proportion of subjects having early diastolic notch in two groups). Materials and Methods: Enrolling 40 subjects with preeclampsia, this study was done in the Department of Radiology & Imaging, Dhaka Medical College Hospital, Dhaka, over a period of six months from 20th June 2014 to 19th December 2014. A total number of 40 normal pregnancies were also included for comparison. Results: Majority (35% in normal and 37.5% in preeclampsia) of the respondents were found in the age group of 21−30 years. Unpaired t-test revealed no significant difference between mean age of two groups. Among normal group, mean±SD of PI and RI were 1.12±0.0846 and 0.571±0.058 respectively and in preeclamptic group mean PI and RI were 2.497±0.369 and 0.8255±0.087. There was statistically significant (by unpaired t-test) difference in mean Doppler indices between these two groups. Early diastolic notch was found in 90% subjects with preeclampsia and 5% subjects with normal pregnancy. Chi-square test showed that there was statistically significant difference regarding presence of early diastolic notch between normal regarding subjects and subjects with preeclampsia. Conclusion: From the study result it was concluded that Doppler indices with presence of early diastolic notch are reliable indicators for early detection of preeclampsia.
