Renal Angioplasty And Stenting
Renal angioplasty is a procedure that employs a small balloon to widen a narrowed or blocked renal artery, which supplies blood to the kidneys. A stent, a small metal mesh tube, may be placed in the artery to keep it open and improve blood flow.
This procedure is typically performed by an interventional radiologist, a trained doctor to perform minimally invasive image-guided procedures for diagnosing and treating diseases. Renal angioplasty and stenting can help improve blood flow to the kidney and alleviate problems such as severely high blood pressure or kidney function issues.

What Happens In Renal Angioplasty And Stenting?
- You will be provided with a hospital gown and positioned on an X-ray table. An IV line will be inserted into your arm or hand to administer fluids and medication, which may include a relaxant.
- Numbing medicine will be applied to the insertion site, usually in the groin. A needle with a thin guide wire will then be inserted through the skin into the blood vessel, followed by the placement of a flexible tube called a catheter over the guidewire into the blood vessel.
- X-ray dye is injected into the blood vessel while the radiologist uses X-ray images (fluoroscopy) for guidance. The catheter is manoeuvred through the blood vessels to reach your kidney.
- Once the angioplasty catheter reaches the narrowed or blocked area, the radiologist inflates a special balloon attached to the catheter to widen the artery (angioplasty). This step may be repeated using balloons of different sizes.
- A stent may be inserted to keep the blood vessel open. A catheter with a stent is guided over the guide wire to the narrowed area, where the stent is expanded. The stent remains in the artery, and the catheters and balloons are removed.
- After the procedure, pressure is applied to the insertion site for 15 minutes to prevent bleeding.
Pre-Operative Care For Renal Angioplasty And Stenting
Follow all instructions provided to you regarding preparation for the procedure, including any fasting guidelines.
Inform your doctor if you:
- Have allergies to X-ray dye or medications
- Are breastfeeding
- Are pregnant or suspect you might be
- Have any health conditions or recent illnesses
Disclose all medications you take, as you may need to discontinue some or all of them before the test. This includes prescription medications, herbs, vitamins, supplements, over-the-counter drugs like aspirin or ibuprofen, and illegal substances.
Post-Operative Care For Renal Angioplasty And Stenting
- You might be instructed to lie flat and keep the leg with the insertion site straight for 6 hours to prevent bleeding.
- In some cases, you may need to stay overnight in the hospital. If not, ensure you have someone to drive you home safely.
- Stay hydrated by drinking plenty of fluids to help eliminate the X-ray dye from your body.
- Follow the doctor’s instructions for caring for the insertion site after returning home.
- If a stent was placed, your doctor may recommend taking aspirin or a blood-thinning medication (anticoagulant) to prevent blood clots. Discuss this with your doctor for further guidance.
Potential Risks Associated With Renal Angioplasty And Stenting
Complications from the procedure may include:
- Bruising or bleeding at the insertion site
- Internal bleeding or bleeding around the insertion site
- Artery damage, potentially worsening blockage and leading to kidney damage or failure, requiring long-term dialysis
- Infection
- Adverse reactions or kidney damage. Complications related to the X-ray dye may include allergic reactions or kidney damage.
