Abstract: There has been increased in studying the development of Intervillous circulation during early pregnancy gestation, made possible by the availability of using transvaginal ultrasound and transvaginal colour Doppler imaging. Objectives: To assess the value of transvaginal ultrasonography and transvaginal colour Doppler imaging in characterizing the Intervillous circulation in normal and abnormal pregnancy. Design: cross-sectional study. Setting: AL-Elwiya Maternity Teaching Hospital, Baghdad-Iraq. Main outcome measures: Comparison of detection of the moving echoes in the Intervillous circulation with grey-scale and colour Doppler imaging in normal and abnormal early pregnancies. Subject and Methods: 162 pregnant women fulfilled the criteria for the inclusion in this study were evaluating for diagnosis and fate of pregnancy. All of the pregnant women were subjected to transvaginal ultrasound and transvaginal colour Doppler imaging examination only once time by using 5-MHz curve liner transvaginal probe, with pulsed colour and power Doppler facilities and real time grey-scale ultrasound were used to evaluate the placenta anatomy and to detect the moving echoes inside the Intervillous space at peripheral and central areas. 67 pregnant women has been subjected to both above examinations at 7-9 weeks, 53 of total 162 at 10-11 weeks and the rest 42 at 12-14 weeks of pregnancy. Results: the overall degree of agreement between the two investigations was good. A significant different distribution of blood flow was found between normal and abnormal pregnancies at 7 to 9 weeks and 10 to 11 weeks but not at 12 to 14 weeks. There is no difference in the use of the transvaginal ultrasound and transvaginal colour Doppler imaging regarding the efficiency of the equipment but it remain dependable on the efficiency of the sonographist. Conclusion: we concluded from this study the beneficial use of the transvaginal ultrasound or transvaginal colour Doppler imaging in estimating the state or the conditions of the placenta in early pregnancy and the results of these examinations may give an idea to some extents about the fate of the pregnancy. Early prediction of pregnancy that ended with abortion during the first trimester for any reason (Genetic, Immunological, Infectious) still represent a big challenge to the clinicians and patients were reflect the many ways for substantiation the pregnancy like Aspirin, Progesterone derivatives. This study shows that simple methods are useful for the prediction of the fate of the pregnancy that liable for abortion.
