Renovascular Hypertension Definition
Renovascular hypertension is High Blood Pressure that is caused by narrowing (stenosis) of one or both of the arteries, called the renal arteries, that supply blood to the kidneys. Narrowing of the renal arteries reduces blood flow to the kidneys. This is a potentially serious condition that requires care from your doctor.
Each kidney is capable of regulating the body's blood pressure to assure that each organ has an adequate supply of oxygenated blood. This happens by activating a cascade of hormones known as the renin-angiotensin system.
Renal Artery Stenosis triggers the release of these hormones, which then becomes a cause for hypertension (high blood pressure). Since hypertension is a leading cause of Stroke and Heart Attack , this is a serious condition that requires diagnosis and treatment.
