Renal Artery Stenting

🩺 What is Renal Artery Stenosis?

Renal Artery Stenosis is a condition where the arteries that carry blood to the kidneys become narrowed or blocked, usually due to fatty deposits (atherosclerosis). This reduces blood supply to the kidneys, leading to uncontrolled high blood pressure and kidney damage.

🔹 Signs and Symptoms

• High blood pressure that is difficult to control with medicines

• Worsening kidney function (high creatinine levels)

• Sudden episodes of breathlessness due to fluid overload

• Swelling in ankles and legs

• In severe cases, recurrent episodes of flash pulmonary edema

🔹 Causes

• Atherosclerosis (plaque buildup) – most common cause

• Fibromuscular dysplasia – abnormal artery structure, often in younger patients

• Rarely, vasculitis or trauma

🔹 Diagnosis

• Doppler Ultrasound of kidneys to assess blood flow

• CT Angiography / MR Angiography for detailed imaging

• Renal Angiography – gold standard to confirm narrowing

🔹 Treatment – Renal Artery Stenting

• A catheter is guided to the narrowed portion of the artery.

• A balloon is inflated to open the blockage.

• A stent (metal mesh tube) is placed to keep the artery open.

🔹 Benefits

• Better control of blood pressure

• Protection of kidney function

• Reduction in risk of heart failure due to hypertension

👉 Renal Artery Stenting is a safe and effective solution that restores blood flow to the kidneys and improves overall health.

🌟 Aortic Stenting (Endovascular Aneurysm Repair – EVAR)

🩺 What is Aortic Stenosis / Aneurysm?

The aorta is the largest artery in the body, carrying blood from the heart to the rest of the body. Sometimes, the aorta may develop:

• Aortic Aneurysm – abnormal bulging or ballooning of the vessel wall.

• Aortic Dissection – a tear in the inner wall of the aorta.
  Both conditions can be life-threatening if not treated promptly.

🔹 Signs and Symptoms

• Often silent in early stages

• Back, abdominal, or chest pain

• Sudden severe pain (tearing or ripping sensation) in cases of dissection

• Dizziness, fainting, or shock in rupture cases

🔹 Causes

• Long-standing hypertension

• Atherosclerosis (cholesterol plaques)

• Genetic conditions (Marfan’s, Ehlers-Danlos syndrome)

• Trauma or infection

🔹 Diagnosis

• Ultrasound / CT Angiography for detecting aneurysm size and location

• MRI for detailed vascular imaging

• Aortic Angiography for interventional planning

🔹 Treatment – Aortic Stenting (EVAR/TEVAR)

• A catheter is inserted through the groin arteries.

• A stent-graft (metal mesh with fabric) is placed inside the weakened aorta.

• This reinforces the aortic wall, preventing rupture or further tearing.

🔹 Benefits

• Minimally invasive alternative to open surgery

• Reduced risk of rupture and life-threatening bleeding

• Shorter hospital stay and quicker recovery

• Effective long-term protection for patients with aneurysm or dissection

👉 Aortic Stenting is a life-saving procedure that provides durable results and improves patient survival in high-risk vascular conditions.
