Renal Artery Angioplasty
Renal artery angioplasty is a minimally invasive procedure for treating blockages in the arteries supplying the kidneys, often due to atherosclerosis. A catheter with an inflated balloon is inserted into the narrowed artery, expanding it to enhance blood flow, relieving kidney dysfunction symptoms and potentially averting complications like high blood pressure or kidney failure.

Symptoms Of Renal Artery Angioplasty
Symptoms
High blood pressure 
Decreased kidney function
Swelling in the legs
Shortness of breathTypes of conditions
There are 2 main types of Renal Artery Angioplasty
Balloon Angioplasty
Stent Placement
Balloon Angioplasty
- A catheter with a deflated balloon is guided into the narrowed renal artery.
- The balloon is inflated, pushing the plaque against the artery wall, widening the artery, and improving blood flow.
Symptoms of Renal Artery Stenosis
- High blood pressure : Renal artery stenosis can restrict blood flow to the kidneys, leading to activation of the renin-angiotensin-aldosterone system, which elevates blood pressure. Despite medication, blood pressure may remain high due to the underlying vascular obstruction.
- Decreased kidney function : Reduced blood flow to the kidneys caused by renal artery stenosis can impair kidney function over time, potentially leading to chronic kidney disease characterized by decreased filtration and retention of waste products in the bloodstream.
- Swelling in the legs : Impaired kidney function can result in reduced sodium and water excretion, leading to fluid retention and swelling in the legs known as edema.
- Shortness of breath : Renal artery stenosis can lead to fluid overload and heart failure, causing symptoms such as shortness of breath, especially when lying down due to fluid accumulation in the lungs (pulmonary congestion).
Diagnosis
Before undergoing renal artery stenting, you will undergo a thorough assessment by a healthcare provider. This assessment includes checking your general health and vital signs such as temperature, pulse, and blood pressure. Additionally, several tests may be conducted to determine the need for renal artery stenting:
-
Duplex Doppler ultrasonography: This test utilizes sound waves to evaluate the size of blockages and the speed of blood flow within the renal arteries.
-
Computed tomography angiogram (CTA): A CT scan creates a 3D image of the kidneys using X-rays. Contrast dye may be injected to highlight the renal arteries.
-
Magnetic resonance angiogram (MRA): Similar to an MRI, MRA uses magnetic fields to produce detailed images of blood vessels. Contrast dye is injected to enhance visibility.
-
Angiogram: During this procedure, a catheter is inserted through the groin into the aorta and advanced to the renal arteries. Contrast dye is injected to visualize blood flow and detect any blockages.
Risk Factors
- Atherosclerosis
- Older age
- Hypertension
- Smoking
- Diabetes
- Family history
- Chronic kidney disease (CKD)
Preparing For Surgery
Before a procedure, disclose all medications, allergies, and any potential interactions with them to your healthcare provider. Discuss any potential bleeding risks and follow specific dietary instructions. An intravenous line will be inserted to administer pain medication and sedatives, allowing you to relax without being unconscious.
Understanding the Procedure
- A small incision is made in the groin or arm.
- A hollow tube known as a sheath is inserted into the artery through the incision.
- Another hollow tube called a catheter is then advanced into the affected renal artery through the sheath.
- A balloon may be inflated to open the blockage in the renal artery.
- A stent, a metal fine mesh tube, is placed across the blockage and deployed to widen the channel for improved blood flow.
- The stent remains in place to sustain blood flow.
- Once properly positioned, the angioplasty catheter is removed, and pressure is applied over the incision site or a specialized device is used to close the artery opening.
- A bandage is placed over the incision to complete the procedure.
Following a procedure, lie flat and keep the leg straight for up to 6 hours to prevent bleeding. Stay overnight for observation and drive home if discharged. Follow post-procedure care instructions, especially wound care at the insertion site. Consult your doctor for personalized advice on blood clot prevention.
Recovery
Renal artery stenting patients undergo a recovery period at the hospital, monitored by healthcare providers. They are advised to have a family member or friend drive them home. During this time, they may be prescribed blood-thinning medications to promote blood flow and prevent clot formation. Medication usage varies and should be consulted with a doctor.

Commonly Asked Questions
When can I go back to work?
Most people can return to work within a week after the procedure. Those with physically demanding jobs may need more time off for healing.
Will renal artery stenting cure renal artery stenosis?
Renal artery stenting enlarges the channel for blood flow to the kidney but may not cure high blood pressure completely, and stenosis can return over time.
How long do renal stents stay in?
Renal stents are permanent implants.
Are renal stents painful?
Renal artery stents aren't typically painful; some may experience mild discomfort during placement.
When is a stent needed for a renal artery?
Stents may be needed for blockages greater than 60% in one or both renal arteries or when blood pressure remains uncontrolled with medications.
How much time does renal angioplasty procedure take?
Renal artery angioplasty typically lasts 1 to 1½ hours, including preparation time, but may vary based on the case.
How long will I need to stay in the hospital after renal angioplasty?
Patients may leave the hospital the same day or stay overnight after the procedure.
Who should not undergo renal angioplasty and stent placement?
Individuals unable to take blood-thinning or antiplatelet medications, or allergic to stent materials, should avoid the procedure.
