Renal Artery Stenosis – Narrowing of the Renal Artery

Renal artery stenosis is a narrowing of one or both arteries that supply blood to the kidneys. Reduced renal blood flow can lead to high blood pressure (renovascular hypertension) and, in severe or bilateral cases, a deterioration of kidney function.

The kidneys respond to reduced blood flow by, among other things, activating the renin-angiotensin-aldosterone system (RAAS). This can cause blood vessels to constrict and increase sodium and fluid retention, which can further raise blood pressure.

Most Common Causes

The two main causes are:

• Atherosclerosis (hardening of the arteries)

• Fibromuscular Dysplasia

In older people, atherosclerotic renal artery stenosis is much more common.

Atherosclerotic Renal Artery Stenosis

In atherosclerosis, deposits form in the artery walls. This can cause the vessel to gradually narrow.

Risk factors include:

• Smoking

• High blood pressure

• Diabetes mellitus

• High blood lipids

• Older age

• Other arteriosclerotic vascular diseases

Vascular changes in the heart, neck, or leg arteries often occur simultaneously.

Fibromuscular Dysplasia

Fibromuscular dysplasia (FMD) is a non-atherosclerotic and non-inflammatory disease of the arterial wall.

It can affect the renal arteries, among others, and is more common in women.

Characteristic changes in the vessel wall can lead to multiple narrowings. A typical "string of beads" appearance may be seen in vascular imaging.

Possible Symptoms

Renal artery stenosis often initially causes no specific symptoms.

Indications may include:

• New onset high blood pressure

• Difficult-to-control high blood pressure

• Suddenly much worse controlled blood pressure

• High blood pressure at an unusually young age

• Deterioration of kidney function

• Kidneys of different sizes

• Recurrent episodes of sudden pulmonary congestion

Renovascular Hypertension

Due to reduced blood flow, the affected kidney, as it were, interprets the situation as too low blood pressure.

It releases more renin, which activates the renin-angiotensin-aldosterone system.

Consequences can include:

• Vessel constriction

• Increase in blood pressure

• Increased sodium retention

• Fluid retention

This can lead to severe and sometimes difficult-to-treat high blood pressure.

Effects on Kidney Function

In severe, especially bilateral, renal artery stenosis, the blood supply to the kidneys can be so severely restricted that kidney function declines.

Long-term, the affected kidney may shrink and lose function.

ACE Inhibitors and AT1 Receptor Blockers

ACE inhibitors and angiotensin receptor blockers (sartans) are important medications for treating high blood pressure and can also be used in many patients with renal artery stenosis.

However, in bilateral high-grade renal artery stenosis or a significant stenosis of the artery of a single functional kidney, kidney function may significantly decrease while on these medications.

Therefore, after starting or changing the dose, checks of:

• Creatinine

• eGFR

• Potassium

may be necessary.

A significant increase in creatinine after starting such treatment can be an indication of relevant renovascular disease and should be medically clarified.

Diagnosis

If renal artery stenosis is suspected, various examinations can be used:

• Blood pressure measurements

• Kidney function check

• Urine tests

• Duplex sonography of the renal arteries

• CT angiography

• MR angiography

• Catheter angiography in selected cases

The choice of examination method depends, among other things, on kidney function, the clinical question, and individual risk factors.

Treatment

Treatment depends on the cause, extent of stenosis, blood pressure, kidney function, and existing complications.

In atherosclerotic renal artery stenosis, consistent medical treatment of vascular risk factors is often initially paramount.

This may include:

• Optimal blood pressure control

• Treatment of high blood lipids

• Treatment of diabetes

• Smoking cessation

• Further measures to reduce cardiovascular risk

Angioplasty and Stent

Not every renal artery stenosis needs to be treated with a stent.

However, in selected patients, revascularization may be useful or necessary, for example by means of balloon dilation or angioplasty and, if necessary, a stent.

This may be considered particularly in certain severe clinical situations, for example, in:

• Recurrent sudden pulmonary congestion or "flash" pulmonary edema

• Certain forms of therapy-resistant hypertension

• Progressive deterioration of kidney function with hemodynamically relevant stenosis

In fibromuscular dysplasia, balloon angioplasty without routine stent implantation can be an important treatment option.

Renal Artery Stenosis and Pulmonary Edema

Severe bilateral renal artery stenosis can in certain cases lead to sudden fluid accumulation in the lungs.

This so-called flash pulmonary edema situation can manifest as:

• Suddenly severe shortness of breath

• Shortness of breath when lying down

• Pronounced increase in blood pressure

• Rapid deterioration of general condition

This is a medical emergency.

Homeopathy according to Dr. Banerji

In homeopathy according to Dr. Banerji, specific homeopathic remedies and potencies are used according to the Banerji protocols for various kidney, vascular, and blood pressure complaints.

A reliable widening of a narrowed renal artery or treatment of a hemodynamically relevant renal artery stenosis by homeopathic remedies is not scientifically proven.

Therefore, necessary nephrological, angiological, or vascular medical diagnostics and treatment must not be replaced or delayed.

Important Note

Renal artery stenosis should be medically clarified, especially in cases of difficult-to-control or suddenly significantly increasing high blood pressure, unexplained deterioration of kidney function, or recurrent episodes of acute pulmonary congestion.

In cases of sudden severe shortness of breath, hypertensive crisis, chest pain, or other signs of acute cardiovascular strain, immediate medical attention is required.
