Renal Artery Stenosis

Welcome to the Renal Artery Stenosis Clinic at Emirates Hospitals Group in Dubai. Our specialized clinic offers comprehensive care for individuals with RAS, focusing on personalized treatment plans to manage symptoms and address underlying causes. Our team of experienced Vascular specialists is committed to providing high-quality care to improve your kidney health and overall well-being.

What is Renal Artery Stenosis ?

Renal Artery Stenosis occurs when one or both of the renal arteries, which supply blood to the kidneys, become narrowed due to plaque buildup or other factors. This narrowing impairs blood flow to the kidneys, which can lead to high blood pressure and potentially cause kidney damage. At Emirates Hospitals Group, we utilize advanced diagnostic tools and treatment options to effectively manage RAS and prevent complications.

Renal Artery Stenosis Treatments

Our clinic provides a range of procedures and treatments for managing Renal Artery Stenosis:

• Lifestyle Modifications: Initial management often includes lifestyle changes such as adopting a heart-healthy diet, regular exercise, and smoking cessation. Our specialists will help you develop a personalized plan to support kidney health and reduce blood pressure.
• Medications: We may prescribe medications to manage blood pressure and improve kidney function. Commonly used medications include antihypertensives (e.g., ACE inhibitors, angiotensin II receptor blockers) and medications to manage cholesterol levels.
• Angioplasty and Stenting: This minimally invasive procedure involves inserting a balloon catheter into the narrowed artery to widen it and improve blood flow. A stent may be placed to keep the artery open and prevent re-narrowing.
• Renal Artery Bypass Surgery: In cases where angioplasty and stenting are not suitable, bypass surgery may be performed to create an alternative pathway for blood flow to the kidneys. This procedure involves grafting a blood vessel to bypass the narrowed segment of the renal artery.
• Endarterectomy: This surgical procedure involves removing plaque from the arterial walls to restore normal blood flow. It is considered for severe cases of RAS.

Renal Artery Stenosis Causes

Renal Artery Stenosis can be caused by several factors, including:

• Atherosclerosis: The most common cause of RAS, where fatty deposits (plaque) build up in the arteries, leading to narrowing and reduced blood flow.
• Fibromuscular Dysplasia: A condition characterized by abnormal growth of the arterial walls, which can cause narrowing of the renal arteries, often affecting younger individuals.
• Blood Clots: Blood clots can obstruct the renal arteries, leading to reduced blood flow and potential kidney damage.
• Inflammatory Diseases: Certain autoimmune or inflammatory conditions can affect the renal arteries, leading to stenosis.

Renal Artery Stenosis Symptoms

The symptoms of Renal Artery Stenosis can vary and may include:

• High Blood Pressure: Elevated blood pressure that is difficult to control with standard medications.
• Kidney Dysfunction: Symptoms of kidney dysfunction, such as swelling, fluid retention, and changes in urination patterns.
• Abdominal or Flank Pain: Discomfort or pain in the abdominal or flank areas.
• Fatigue: General fatigue or weakness due to decreased kidney function.

If you experience any of these symptoms, it is important to seek medical evaluation to determine the appropriate treatment.

Renal Artery Stenosis Diagnosis

Diagnosing Renal Artery Stenosis involves a combination of medical history, physical examination, and diagnostic tests:

• Medical History and Physical Examination: Our specialists will review your medical history and perform a physical examination to assess symptoms and risk factors.
• Imaging Studies: Imaging techniques such as Doppler ultrasound, CT angiography, or MRI may be used to visualize the renal arteries and identify areas of narrowing.
• Blood Tests: Blood tests may be conducted to assess kidney function and check for markers of kidney damage.
• Renal Artery Angiography: This diagnostic procedure involves injecting a contrast dye into the renal arteries to obtain detailed images and evaluate the extent of stenosis.

Renal Artery Stenosis Recovery Process

Managing and recovering from Renal Artery Stenosis involves a combination of medical treatment, lifestyle changes, and ongoing care:

• Ongoing Management: Regular follow-up appointments are essential for monitoring your condition and adjusting treatment as needed. Our specialists will work with you to ensure effective management of RAS.
• Lifestyle Changes: Implementing lifestyle modifications, such as a heart-healthy diet, regular exercise, and smoking cessation, can significantly improve symptoms and overall health.
• Medication Adherence: Taking prescribed medications as directed is crucial for managing blood pressure and preventing further complications.
• Patient Education: We provide comprehensive education on managing Renal Artery Stenosis, including information on recognizing symptoms, adhering to treatment plans, and making lifestyle changes to support your recovery.
