Renovascular hypertension is a significant cause of severe renal disorders. Read this article to know more.

Renovascular Hypertension


Renovascular hypertension is a condition where there are higher blood pressure levels, and the kidneys contribute to this increased level. It happens due to the narrowing of the arteries carrying the blood to the kidneys. The other name for renovascular hypertension is renal artery stenosis. There are various causes and risk factors associated with renovascular hypertension. There are several treatment options. Surgical methods are known to be highly beneficial. The patient should be educated about their condition so that they can take care of their health in a better manner.

What Is the Epidemiology of Renovascular Hypertension?

Renovascular hypertension is known to be the second most common condition occurring in the United States of America. Older people are most commonly affected than younger people. In some patients, renovascular hypertension can occur at the age of 30, while in others, it can affect patients who are more than 50 years of age.

What Are the Causes of Renovascular Hypertension?

The main cause of renovascular hypertension is higher levels of cholesterol. The risk is increased when a fatty substance is known to thicken the inner lining of the arteries. This fatty substance is known as plaque, and this condition is referred to as atherosclerosis. The narrowing of the arteries results in reduced blood flow than normal. In response to this, the kidneys release hormones that lead to increased salt and water retention. As a result, blood pressure increases. A few conditions are known to cause renovascular hypertension. They are:

Does Renovascular Hypertension Affect Children?

In children, renovascular hypertension can occur both in congenital and acquired forms. The acquired type of renovascular hypertension is known to be more common than the congenital type. The occurrence of this health condition might vary in different geographical regions. The acquired type of renovascular hypertension can show the following conditions. They are:

What Are the Signs and Symptoms of Renovascular Hypertension?

The condition of renovascular hypertension will show the following signs:

What Are the Complications of Renovascular Hypertension?

The complication associated with renovascular hypertension are:

What Are the Risk Factors of Renovascular Hypertension?

The risk factors associated with renovascular hypertension are:

What Are the Diagnostic Procedures for Renovascular Hypertension?

In the initial stages, diagnosis is made using ultrasonography and magnetic resonance angiography. In some patients, procedures like radionuclide imaging are used. Confirmatory diagnosis is achieved by renal angiography. This procedure can also be used for therapeutic procedures. Renal angiography is a highly beneficial test. It would require a few other tests like radionuclide imaging, magnetic resonance angiography, and ultrasonography to identify whether the patient is eligible for the renal angiography test.

Duplex doppler ultrasonography is also a useful diagnostic test that can identify the blood flow to the kidneys. It is a non-invasive procedure, and it is usually reliable. Stenosis in the renal arteries can be identified with this method. It is a technique sensitive procedure and would require qualified technicians to perform the test.

Radionuclide imaging is a diagnostic procedure that is done before and after the administration of drugs like Captopril. It is an angiotensin-converting enzyme inhibitor (ACE inhibitor). It will help in treating the narrow affected artery.

Digital subtraction angiography is a diagnostic procedure in which the renal arteries are given a selective injection to make a confirmatory diagnosis.

What Are the Treatment Options for Renovascular Hypertension?

The treatment requires certain lifestyle modifications and medications. The patient should be aware of the cholesterol levels as it can increase the risk of other conditions.

What Are the Precautionary Measures?

How Is the Prognosis?

If the blood pressure is relatively higher, then the prognosis is very poor. Proper control of hypertension will help the patient to escape from complications and retain a long life.
