Study Notes
Effects of Venous Congestion
- Venous congestion decreases renal blood flow and glomerular filtrate.
- Left-sided heart failure can lead to right-sided heart failure, causing venous congestion.
- Venous congestion increases pressure in venules, leading to increased fluid filtration and edema.
Venous Hydrostatic Pressure
- Increased venous hydrostatic pressure is caused by reduced venous return to the heart.
Effects on Water and Salt Retention
- Venous congestion leads to increased water and salt retention due to increased aldosterone secretion.
Causes of Chronic Localized Venous Congestion
- Chronic localized venous congestion is often caused by venous thrombosis or venous obstruction.
