Can you stent a renal artery?

A renal artery angioplasty and stent is done to treat a narrowed renal artery. Using X-rays as a guide, a small plastic tube is put into the narrowed artery. A special balloon on the tube is blown up to open the narrowed part of the artery. An expandable tube called a stent is then put in to keep the artery open.

How successful are renal artery stents?

The success rate of renal artery stent was 99.3%. At 12 months, estimated glomerular filtration rate increased significantly compared with baseline (84.1 ± 28.8 vs.

Does angioplasty cure renal artery stenosis?

In most cases, the angioplasty and stenting procedure does not cure renal artery stenosis, but it can slow the progress. Many patients with renovascular hypertension continue to take blood pressure medicine.

Is a renal artery stent permanent?

Next, your vascular specialist typically places a stent—a wire mesh tube—in the blood vessel to act as “scaffolding.” The stent keeps the artery open, increasing blood flow to the kidneys. The stent remains in place permanently.

Why would you need a renal angioplasty?

If the renal arteries are narrowed and the blood flow is restricted, they can be stretched with a balloon (angioplasty) to improve blood flow, reduce blood pressure and maintain better kidney function.

How is renal angioplasty performed?

A small flexible tube called a catheter can be positioned inside the renal artery. An angioplasty is performed by using a catheter that has a tiny balloon attached to the end. The angioplasty balloon is inflated inside the vessel and presses any plaque (blockage) into the walls of the vessel.

How long does renal stent last?

You’ll probably have the stent for a few days or weeks. Some people need stents for months or years. People who have tumors that press on the ureters or narrowed ureters may need ureteral stents for an extended time. Your provider will replace the stent with a new one every three to six months.

Who performs renal artery stenting?

Your interventional cardiologist or other vascular specialist may recommend renal (kidney) artery angioplasty and stenting to open the blocked arteries and restore blood flow to your legs. Angioplasty is a procedure performed in the catheterization laboratory, or “cath lab,” in a hospital.

Is angioplasty safe for kidney patients?

Physicians have cautioned that the use of dyes and x-rays involved in angiography puts kidney patients at an increased risk of complications from the procedure. There have also been concerns that contrast-induced nephropathy and cholesterol embolization syndrome may precipitate the need for chronic dialysis.

What kind of doctor does renal angioplasty?

What is a renal angioplasty?

Renal artery angioplasty is a procedure to widen the opening of the renal arteries that supply blood to the kidney. Narrowing of the renal artery (renal artery stenosis) is the leading cause of this artery obstruction. Renal artery stenosis is mostly caused by atherosclerosis or fibrous disease of the arteries.

What is renal artery angioplasty and stenting?

Renal Artery Angioplasty and Stenting. Your interventional cardiologist or other vascular specialist may recommend renal (kidney) artery angioplasty and stenting to open the blocked arteries and restore blood flow to your legs. Angioplasty is a procedure performed in the catheterization laboratory, or “cath lab,” in a hospital.

What happens after angioplasty and stenting?

After the placement of the stent, your doctor will remove all of catheters. Most patients with kidney (renal) artery disease who are treated with angioplasty and stenting are released from the hospital 12 to 24 hours after the catheter is removed.

How is angioplasty performed in a hospital?

Angioplasty is a procedure performed in the catheterization laboratory, or “cath lab,” in a hospital. You will lie on a table and be mildly sedated to help you relax, but you will remain awake throughout the procedure. A thin flexible tube called a catheter will be inserted into the artery and threaded through the arteries to the blockage.

How long does it take to recover from angioplasty?

Most patients with kidney (renal) artery disease who are treated with angioplasty and stenting are released from the hospital 12 to 24 hours after the catheter is removed. Many patients are able to return to work within a few days to a week after a procedure.
