What is renovascular stenosis?

In renal artery stenosis, one or both of the arteries leading to the kidneys becomes narrowed, preventing adequate blood flow to the kidneys. Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries).

Which condition is a common complication of renal artery stenosis?

Renal artery stenosis is a narrowing of arteries that carry blood to one or both of the kidneys. Most often seen in older people with atherosclerosis (hardening of the arteries), renal artery stenosis can worsen over time and often leads to hypertension (high blood pressure) and kidney damage.

What is the most common symptom of renal artery stenosis?

The kidneys play an important role in regulating blood pressure by secreting a hormone called renin. If the renal arteries are narrowed or blocked, the kidneys cannot work effectively to control blood pressure. Persistent or severe high blood pressure is a common symptom of renal artery stenosis.

What is treatment for renal artery stenosis?

Procedures to treat renal artery stenosis may include: Renal angioplasty and stenting. In this procedure, doctors widen the narrowed renal artery and place a device (stent) inside your blood vessel that holds the walls of the vessel open and allows for better blood flow.

Can you have renal artery stenosis without hypertension?

Renal artery stenosis is a cause of end stage renal failure, and patients commonly present with chronic renal failure (with or without hypertension).

Is renal artery stenosis considered chronic kidney disease?

Many but not all patients with atherosclerotic renal artery stenosis have chronic kidney disease (CKD) that is primarily due to a reduction in blood flow induced by the stenosis.

Does creatinine increase with renal artery stenosis?

The degree of stenosis is higher than 80% The serum creatinine level increases after administration of angiotensin-converting enzyme inhibitors. The degree of stenosis is 50% to 80%, and the scintigraphy results are positive for RAS.
