The use of venous Doppler to predict adverse kidney events in a general ICU cohort
Critical Care, 2020 Background Changes in Doppler flow patterns of hepatic veins (HV), portal vein (PV) and intra-renal veins (RV) reflect right atrial pressure and venous congestion; the feasibility of obtaining these assessments and the clinical relevance of the findings ...

Simultaneous self-organization of arterial and venous networks driven by the physics of global power optimization [PDF]
arXiv, 2023 Understanding of vascular organization is a long-standing problem in quantitative biology and biophysics and is essential for the growth of large cultured tissues. Approaches are needed that (1) make predictions of optimal arteriovenous networks in order to understand the natural vasculatures that originate from evolution (2) can design vasculature for

Renal Venous Congestion and Renal Function in Congestive Heart Failure
Journal of the American College of Cardiology, 2009 Jessup and Constanzo ([1][1]) recently proposed mechanisms explaining the reported inverse relationship between central venous pressure (CVP) and glomerular filtration rate (GFR) in congestive heart failure (CHF) ([2,3][2]).

Venous Excess Doppler Ultrasound for the Nephrologist: Pearls and Pitfalls
Kidney Medicine, 2022 The role of venous congestion in abnormal kidney function is being increasingly recognized. It is well known that unresolved congestion is associated with adverse kidney and overall outcomes in patients with heart failure.

Optical Hemodynamic Imaging of Jugular Venous Dynamics During Altered Central Venous Pressure [PDF]
arXiv, 2020 An optical imaging system is proposed for quantitatively assessing jugular venous response to altered central venous pressure. The proposed system assesses sub-surface optical absorption changes from jugular venous waveforms with a spatial calibration procedure to normalize incident tissue illumination.

Congestion Control in Computer Networks: Trends and Issues [PDF]
IEEE Network, May 1990, pp. 24-30, 1998 Popular myths that cheaper memory, high-speed links and high-speed processors will solve the problem of congestion in computer networks are shown to be false. A simple definition for congestion based on supply and demand of resources is proposed and is then used to classify various congestion schemes.

Venous Thromboembolic Disease in Congestive Heart Failure [PDF]
Congestive Heart Failure, 2010 Congestive heart failure (CHF) is a medical condition associated with a relatively high risk of venous thromboembolism (VTE). Without thromboprophylaxis, venographically proven deep vein thrombosis occurs in 10% to 22% of hospitalized patients with CHF. Although the elevated VTE risk associated with CHF has been attributed to a variety of abnormalities
