Flashcards

Effect of Venous Congestion on Renal Function

Venous congestion leads to a decrease in renal blood flow and glomerular filtrate.

Pulmonary Congestion from Left-Sided Heart Failure

Left-sided heart failure can cause pulmonary congestion due to a backup of blood in the lungs.

Cyanosis from Venous Congestion

Venous congestion leads to a buildup of deoxygenated blood in the venules, causing a bluish discoloration of the skin called cyanosis.

Edema from Venous Congestion

Increased venous hydrostatic pressure can lead to fluid buildup in the tissues, causing edema.

Water and Salt Retention due to Venous Congestion

Venous congestion can cause the body to retain water and salt, potentially leading to fluid overload.

Cause of Chronic Localized Venous Congestion

A blood clot (thrombosis) in a vein can cause chronic localized venous congestion.

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.
