Features of hemodynamic changes in spiral arteries with low placentation at the early gestational age

Abstract

Abstract. The article presents the results of Doppler studies in spiral arteries of indices of resistance and blood flow velocities in the I trimester of gestation in pregnant women with low placentation. As a result of the studies, a significant increase in resistance and a decrease in blood flow rates in early pregnancy in pregnant women with low placentation was found in comparison with normal placement of the chorion, which may be a factor of high risk of primary placental dysfunction development in the future.
