Balloon Angioplasty and Stent Placement
For many people, the passing years also include the buildup of plaque in their arteries. Plaque consists of cholesterol, calcium, and fibrous tissue and it sticks to the walls of the blood vessels. As more and more plaque accumulates, your arteries narrow and stiffen, a process we refer to as arteriosclerosis. This narrowing reduces blood flow and can lead to chest pain or shortness of breath if the arteries of the heart are involved as well as leg pain or numbness if there is a blockage in the arteries of the legs.
At Premier Cardiology Consultants, we use balloon angioplasty, often with the placement of a stent, to open the blockage and to minimize the chances of a blockage recurring in the same location.

During angioplasty, we insert a balloon catheter, often mounted with a stent, into the artery with the blockage. We move the catheter to the area of the blockage and expand the balloon. This compresses the plaque against the wall of the artery and reduces the blockage, returning better blood flow. We deflate the balloon, but the stent remains in place keeping the artery open.
What is a stent?
Known mostly for their use with coronary artery disease, where stents have been widely used for over 20 years, stents can also be used in the leg arteries for the same purpose — to hold the artery open to maintain blood flow — in cases of peripheral artery disease.
Stents are basically like a scaffold that is inserted into your artery at the location of the blockage. This framework supports the artery walls, keeping them open and reducing the chances of recurrent blockage or narrowing after angioplasty. Stents consist of an expandable mesh tube made of medical-grade stainless steel or cobalt alloy metal. Stents can also consist of materials that your body absorbs over time. Some also have a medicated coating to help prevent re-narrowing or the formation of clots at the site of insertion.
Balloon angioplasty and stent placement Procedure
Whether for a coronary artery or a lower body artery, the procedure is the same. The area where the catheter will be inserted is numbed with a local anesthetic. Then our vascular surgeons thread a thin wire into the blocked artery through a needle usually inserted into the blood vessel in your groin. We insert a small amount of contrast liquid into your blood vessel through the catheter. This allows us to track the catheter as it moves through the artery.
If inserting a stent, we will mount it onto a tiny balloon prior to insertion. Then we will move the catheter through the artery to the location of the blockage. Next, we inflate the balloon to push the plaque outward and stretch the artery open to boost blood flow to the heart or down the legs. If we are also inserting a stent, when the balloon opens the stent expands to the size of the artery and holds it open. We will then deflate and remove the balloon while the stent remains in place. Over a few weeks, your artery heals around the stent and it remains in place permanently.
recovery from an angioplasty and Stent Placement
After the procedure you will need to rest in bed for up to 24 hours, lying flat for the first few hours. You’ll usually stay in the hospital for one night, returning home the following day. You can usually resume most activities in just a day or two, but strenuous activity will have to wait a few weeks. If you received a stent, you’ll take medications to reduce the odds of forming a blood clot near the stent.
What Are The risks involved with A angioplasty?
Angioplasty and stent placement are generally safe and very successful. There are risks involved, however, and the Premier Cardiology team will discuss them with you. They involve the following:
- Heart attack
- Damage to the artery
- Injury to the groin at the catheter insertion point
- Formation of a blood clot at the stent location
- Possible bleeding
In some patients, the arterial blockage can return within six months, although this is far less likely with a stent in place.
angioplasty Failure and Other options At Premier Cardiology
If angioplasty or atherectomy is not successful in opening a clogged artery, or for some reason is not an option, bypass surgery is often the next treatment option. In this surgery, the blocked artery is simply bypassed. While coronary bypass surgery is more common, leg arteries can also be bypassed if not responding to treatment.
