Renal Artery Stenting and Bypass

Surgical Associates of Marshall County offers treatment for renal artery conditions, including renal artery stenting and bypass in Albertville and Guntersville.

When blood flow is restricted in the renal arteries, it limits the amount of oxygen-rich blood that reaches the kidneys, which can result in an increase in blood pressure, damage to the kidneys and hinder kidney functioning. Often, this restriction requires surgical correction, which can be performed by the expert surgeons at Surgical Associates of Marshall County.

What Causes Renal Artery Conditions?

The kidneys are responsible for filtering waste from the body and need the blood provided by the two renal arteries to function properly. When this circulation is restricted by the build-up of fatty plaque along the artery walls it is known as renal artery stenosis, which can lead to reduced kidney function and kidney failure.

Risk factors for renal artery stenosis include:

  • High cholesterol
  • Smoking
  • Obesity
  • Diabetes
  • Advanced age
  • Family history of cardiovascular disease

The condition often does not produce symptoms until it worsens. You may not notice the issue until your blood pressure rises significantly, your kidneys cease functioning effectively or your doctor notices abnormal laboratory values or other indicators noticeable during a routine physical examination.

Renal artery restriction may also result from renal vein thrombosis, in which a blood clot breaks free to become lodged in a renal artery. Renal vein thrombosis is often caused by nephrotic syndrome, infection, arterial injury or tumor and may cause symptoms like:

  • Leg swelling
  • Enlarged kidney
  • Abdominal or leg pain
  • Blood or protein in urine
  • Vomiting, nausea or fever
  • High blood pressure
  • Breathing difficulties

If you believe you may be suffering from or at risk of renal artery restriction, contact Surgical Associates of Marshall County immediately to undergo testing and receive renal stenting and bypass treatments.

Treatment of Renal Artery Conditions

Your surgeon may use open or endovascular surgery to relieve renal artery restriction. The form of surgery used will depend largely on the nature of your condition.

  • Renal angioplasty and stenting will often be used to correct renal artery stenosis. This procedure is performed by guiding a small balloon through the artery to the area of the blockage. The balloon is inflated to even out the plaque build-up and a tube of wire mesh (stent) is inserted to support the artery walls and prevent further restriction.
  • Renal artery bypass may need to be performed when stenting proves ineffective. This procedure involves attaching a substitute artery to the renal artery, providing a secondary route for blood to reach the kidneys.

Your surgeon will be able to determine which surgical method will be safest and most effective in treating your condition using diagnostic procedures like CT scan, angiography, ultrasound or arteriogram.
