Изменение скорости кровотока в системе почечных сосудов на фоне гипертензии, индуцированной беременностью

Abstract

Objective. The aim of the research was to determine if the pregnancy-induced hypertension (PIH) influences the Doppler measurements of segmental and interlobular renal blood flow in comparison to healthy pregnant women. The complex examinations of 43 healthy pregnant women on the 10-14th and 28-32nd weeks of gestation was held. On the 10-14th weeks of pregnancy, which later was complicated by preeclampsia, hemodynamic changes in renal arteries were found, such as: the elevation of peripheric vascular resistance in common renal and segmental arteries (the increased RI, S/D) in comparison to physiological pregnancy. The elevation of systolic to diastolic ratio S/D more than 3.0 in the main stem of common renal and segmental arteries is an early sign of preeclampsia in healthy pregnant women.
