Organ congestion from venous hypertension is an important pathophysiological mechanism
mediating organ injury in several clinical contexts including critical illness, congestive heart …

It is generally accepted today that there are two different types of preeclampsia: an early‐
onset or placental type and a late‐onset or maternal type. In the latent phase, the first one …

Although the importance of congestion in the disease progression of heart failure has long
been recognized (1), much has focused on how cardiac impairment can lead to renal …

Objectives: To provide reference values of intrarenal venous impedance index (VII)
measured with duplex Doppler ultrasonography in a healthy adult population and to assess …

The venous compartment has an important function in regulation and control of cardiac
output. Abnormalities of cardiac output have been found in early gestational stages of both …

This review summarizes current knowledge from experimental and clinical studies on renal
function and venous hemodynamics in normal pregnancy, in gestational hypertension (GH) …

Objective: To define normal values of Renal interlobar vein impedance index (RIVI)
throughout gestation, as a reference to RIVI in preeclampsia (PE). Methods: Longitudinal …

Objective. The elevation in blood pressure associated with preeclampsia appears to be
associated with a shift in the renal pressure natriuresis curve. Pressure natriuresis is …

Maternal ureterohydronephrosis (UHN) is a common anatomical change during the
evolution of pregnancy, diagnosed especially after the 20th week of pregnancy. The aim of …

Objectives To test the hypothesis that Doppler characteristics of maternal renal interlobar
veins (RIV) are different between pregnancies affected by early‐onset pre‐eclampsia (EP) …
