Benign Renovascular Hypertension: Signs and Symptoms

Renovascular hypertension, also known as renal artery stenosis, is a condition where the narrowing of arteries that carry blood to the kidneys leads to high blood pressure. The symptoms can vary in severity and may not always be present. Here are some common signs and symptoms:

• High Blood Pressure: One of the primary symptoms of renovascular hypertension is high blood pressure at an early age or very high blood pressure that cannot be controlled with medication [1].
• Kidney Dysfunction: As the kidneys do not receive enough blood, they may start to dysfunction, leading to symptoms such as fatigue, frequency of urination, headaches, dry skin, appetite changes, weight loss, nausea and vomiting [5][6].
• Narrowing of Arteries: The narrowing of arteries throughout the body can lead to a range of symptoms, including chest pain, nosebleeds, and bloody urine [6].
• Difficulty Controlling Blood Pressure: People with renovascular hypertension may experience high blood pressure that is difficult to control with medication [12][14].

It's essential to note that these symptoms can be similar to those experienced by people with other conditions. Therefore, a proper diagnosis by a healthcare professional is necessary for an accurate assessment.

Diagnostic Tests for Benign Renovascular Hypertension

Benign renovascular hypertension, also known as renovascular hypertension, can be diagnosed using various diagnostic tests. These tests help evaluate the blood flow in the renal arteries and identify any potential blockages or narrowing that may be contributing to high blood pressure.

• Ultrasound: An ultrasound test can check blood flow in the renal arteries and detect any abnormalities, such as stenosis (narrowing) or thrombosis (clotting). [1]
• Renal Arteriography: This is considered the gold standard diagnostic test for renovascular hypertension. It involves injecting a contrast agent into the bloodstream to visualize the blood flow in the renal arteries. [2]
• Magnetic Resonance Angiography (MRA): MRA is a non-invasive imaging test that uses magnetic fields and radio waves to create detailed images of the blood vessels, including the renal arteries. It can help identify any narrowing or blockages. [11]
• Computed Tomographic Angiography (CTA): CTA is another non-invasive imaging test that uses X-rays and a contrast agent to visualize the blood flow in the renal arteries. It can also detect any abnormalities, such as stenosis or thrombosis. [11]

These diagnostic tests are essential for diagnosing benign renovascular hypertension and determining the best course of treatment.

[2] Context 2: There are multiple imaging modalities available to evaluate renovascular hypertension. Since the most common cause of renovascular hypertension is renal artery stenosis, renal arteriography remains the gold standard diagnostic test.

[11] Context 11: For patients with normal renal function but a high clinical index of suspicion for renovascular disease, contrast-enhanced magnetic resonance angiography and computed tomographic angiography are the most accurate imaging tests.

Medications for Benign Renovascular Hypertension

The primary goal of drug treatment in benign renovascular hypertension (RVHT) is to control high blood pressure and prevent further complications [4]. Antihypertensive medication therapy is indicated as the first line of treatment, with optimal blood pressure control playing a crucial role in therapeutic management [4].

Medications Used

• Antihypertensive medications: These are prescribed to lower blood pressure and may slow the progression of kidney disease [7].
• Water pills (diuretics): These drugs help remove sodium and water from the body, often used as the first medicines to treat high blood pressure [8].

Treatment Approach

A combination of lifestyle changes and medications is usually recommended. The goal is to normalize blood pressure or improve its control with medications, and improve or stabilize kidney function [14]. If medical management is insufficient, interventional radiologists can perform angioplasty and stenting to improve blood flow to the kidney [14].
