What is a Stent Procedure?
Arterial stenting is commonly used to treat conditions such as peripheral arterial disease (PAD), carotid artery disease, and coronary artery disease (CAD). Stenting can restore blood flow to the heart in CAD, improve blood flow to the legs in PAD, and help prevent strokes in carotid artery disease.
A stent procedure, also known as stenting, is a minimally invasive medical treatment used to open narrowed or blocked arteries or veins to restore normal blood flow to various body parts. Stenting is commonly used to treat conditions such as peripheral artery disease, carotid artery disease, and coronary artery disease. This procedure is essential for treating several cardiovascular and peripheral vascular conditions, including opening clogged arteries in the heart (heart arteries) and peripheral arteries, ensuring that vital organs receive an adequate supply of oxygen-rich blood.
Definition of a Stent:
A stent is a tiny, expandable metal mesh coil that is put into the newly opened area of the artery to help keep it from narrowing or closing again. In peripheral arteries, a stent acts as a scaffold to prevent the artery from closing again after it has been opened.
How Does Stenting Work to Improve Blood Flow?
The procedure begins with a tiny needle puncture at the insertion site. Local anesthesia is administered to numb the area, ensuring patient comfort, and the procedure typically takes 30 minutes to 3 hours. A flexible tube called a catheter (also referred to as a thin tube) is then inserted through the blood vessel. Contrast dye is injected, and x ray imaging is used to visualize the arteries and guide the catheter to the affected area. During a stent procedure, a small mesh tube made of metal or plastic, known as a stent, is delivered to the blockage site using the catheter. A tiny balloon on the catheter is then inflated, expanding the stent and pressing it against the artery walls. This effectively opens the artery, allowing blood to flow more freely. The balloon is then deflated and withdrawn while the stent remains permanently placed, acting as a scaffold to keep the artery open.
Next, let’s explore the different types of stents available and how they are selected for each patient.
Types of Stents
There are various types of stents used depending on the specific need and condition being treated. The two primary categories are:
-
Bare-metal stents (BMS): These stents do not contain medication. They act solely as a scaffold to prevent the artery from closing again.
-
Drug-eluting stents (DES): DES are coated with medication that slowly releases into the artery walls to prevent the growth of scar tissue, which can help reduce the risk of the artery narrowing again. Most stents used today are drug-eluting stents, as they are the most common type and are specifically designed to prevent scar tissue growth inside the stent.
Now that you know the types of stents, let’s look at the conditions that can be treated with stenting.

Conditions Treated by Stenting: Peripheral Artery Disease and More
Stenting is used to treat a range of conditions, including, but not limited to:
-
Coronary artery disease (CAD): This is the most common use of stents, helping to alleviate symptoms such as chest pain (angina) and to minimize damage during a heart attack.
-
Peripheral arterial disease (PAD): PAD occurs when fatty deposits build up in the peripheral arteries, causing them to narrow or block blood flow. These blockages can lead to symptoms such as pain, achiness, or heaviness in the legs that worsens with walking and may be associated with leg swelling and other symptoms. Stenting and angioplasty are used to open blocked peripheral arteries—such as the iliac, femoral, popliteal, tibial, and peroneal arteries—restoring blood flow and helping to heal ulcers on legs and feet, and are often complemented by treatment of related venous issues such as varicose veins and their management.
-
Renal artery stenosis: Stenting can improve kidney blood flow in patients with narrowed arteries.
-
Carotid artery disease: To reduce the risk of stroke, stents may be placed in the carotid arteries, which supply blood to the brain.
Now that you know the main conditions treated by stenting, let’s review the benefits and risks of the procedure.
Benefits and Risks
Benefits of Stenting
The primary benefit of a stent procedure is restoring blood flow through arteries that were previously narrowed or blocked, which can significantly improve quality of life and reduce the risk of heart attack or stroke. Most stents are designed to prevent re-narrowing of the artery by providing structural support and, in some cases, releasing medication.
Risks of Stenting
However, as with any medical procedure, there are risks involved. These include:
-
Infection at the catheter insertion site
-
Abnormal heart rhythms
-
Stroke (though rare)
-
Rupture of the coronary artery (which may require open heart surgery)
-
Allergic reactions to the contrast dye
-
Kidney damage from the contrast dye
-
Scar tissue formation inside the stent (may require a repeat procedure)
-
Bleeding at the catheter insertion site
-
Reactions to the dye used during the procedure
Certain conditions and medications, such as bleeding disorders and blood thinning medicines, can affect blood clotting and should be discussed with your healthcare provider before the procedure. It is important to inform your care team about any history of bleeding disorders or use of blood thinning medicines, as these can affect blood clotting and procedural safety.
In rare cases, blood clots can form within stents. To prevent blood clots and tissue overgrowth inside the stent, antiplatelet medicines are prescribed as an important part of post-procedure management. These medicines help reduce the risk of restenosis and ensure the longevity of the stent, which is especially important in severe PAD presentations such as rest pain and critical limb ischemia.
Most patients can resume normal activities soon after recovery. Lifestyle changes such as smoking cessation and healthy eating are essential to prevent new blockages after stenting.
Understanding the benefits and risks helps you make informed decisions. Let’s see how stenting relates to angioplasty and other procedures.
Understanding the Relation Between a Stent Procedure and Angioplasty
What is Angioplasty?
When it comes to interventions to improve blood flow through the arteries, two common and often interconnected treatments are angioplasty and stent procedures. The combination of angioplasty and stenting is often referred to as coronary angioplasty or called percutaneous coronary intervention (PCI). PCI is a minimally invasive procedure used to treat blocked coronary arteries, often involving balloon angioplasty and stent placement to restore blood flow. Angioplasty and stenting can also be used as emergency treatments for heart attacks caused by blocked coronary arteries. Understanding how these procedures relate to each other helps us appreciate their roles in treating arterial blockages, which are commonly due to conditions such as Peripheral Arterial Disease (PAD) and coronary artery disease and can present with symptoms like claudication, or leg pain with walking.
How Stenting Complements Angioplasty
Angioplasty is a minimally invasive procedure designed to open narrowed or blocked arteries that can block blood flow. During this procedure, a catheter with a tiny balloon on its tip is threaded through a blood vessel to the affected artery. Once in place, the balloon is inflated to widen the artery, pressing plaque against the artery walls and restoring blood flow. In some cases, an atherectomy may be performed to remove plaque from the artery to improve blood flow.
While angioplasty alone can be an effective way to improve blood flow, arteries may sometimes begin to narrow again over time, a process known as restenosis or re-narrowing. This is where stent procedures come into play. A stent—a small, metal mesh tube—is placed in the newly widened area during angioplasty. The stent expands with the balloon and stays in place after the balloon is removed. Most stents are specially designed to prevent the artery from re-narrowing after the procedure, often by releasing medication or providing structural support as part of a broader strategy to manage peripheral artery disease progression. It acts as a supportive scaffold to keep the artery open and maintain proper blood flow long term
Advantages of Combined Treatment
- Reduced Risk of Repeat Blockages: With the stent in place, the likelihood of the artery narrowing again decreases significantly compared to angioplasty alone.
- Restores Blood Flow and Quick Recovery: The combined procedure restores blood flow to blocked arteries, is minimally invasive, and often allows most patients to resume normal activities quickly after treatment.
- Enhanced Blood Flow: The combined approach ensures that the artery remains open, providing consistent and improved blood flow
- Decreased Symptoms: For patients with heart-related conditions, this can mean relief from symptoms such as chest pain and shortness of breath. For PAD, it can improve symptoms like leg pain with walking.

Do You Have Questions?
What is an arterial stenting procedure?
Why would someone need an arterial stent?
A stent may be recommended when plaque buildup (atherosclerosis) restricts blood flow and causes symptoms or increases health risks. It’s commonly used to treat peripheral artery disease (PAD), including blockages in the legs, and may also be used in other arteries depending on your condition.
What symptoms can arterial stenting help with?
Many patients seek care for symptoms such as:
- Leg pain or cramping when walking (claudication)
- Leg numbness, heaviness, or fatigue
- Coldness in the foot or lower leg
- Slow-healing sores or ulcers on the feet/legs
- Pain in the feet or toes at rest (more severe disease)
How is arterial stenting performed?
Most arterial stenting is done through a small puncture (often in the groin or arm). Using imaging guidance, your provider threads a thin catheter to the narrowed area, opens the artery (often with a balloon), and places the stent to support the artery wall and maintain blood flow.
Will I be awake during the procedure?
Many patients receive local anesthesia at the access site plus medication to help them relax (sedation). You may be awake but comfortable. Your care team will walk you through what to expect based on your medical history.
How long does an arterial stenting procedure take?
How long does a stent last?
Stents are designed to be permanent. Many patients do well long-term, but ongoing artery health depends on factors like smoking, diabetes control, cholesterol, blood pressure, and medication adherence. Follow-up visits and imaging may be recommended to monitor results.
