Vascular Stenting

Vascular stenting is a minimally invasive procedure that treats narrowed or blocked blood vessels, commonly caused by atherosclerosis (buildup of plaque) or other vascular conditions. The goal of vascular stenting is to restore normal blood flow through these vessels, improving circulation and reducing the risk of complications such as heart attacks, strokes, and limb amputation. At Prospero Vascular, our interventional radiologists specialize in the safe and effective use of vascular stents to treat a variety of vascular issues, ensuring a quick recovery and fewer complications compared to traditional surgical interventions.

What is Vascular Stenting?

Vascular stenting involves the placement of a small, mesh-like tube, called a stent, into a narrowed or blocked blood vessel. The stent holds the blood vessel open, allowing blood to flow freely through it once again. Specialists typically use stents to treat arteries or veins that have become narrowed due to the accumulation of plaque or blood clots.

Specialists typically perform the procedure through a minimally invasive technique using a catheter, guided by real-time imaging such as fluoroscopy (X-ray) or ultrasound, to navigate to the affected vessel. The specialist then inserts and expands the stent at the site of the blockage, improving blood flow.

Why is Vascular Stenting Performed?

Specialists commonly perform vascular stenting to treat the following conditions:

• Atherosclerosis: The buildup of fatty deposits (plaque) in the arteries, leading to narrowing and reduced blood flow. This can occur in arteries supplying the heart (coronary arteries), brain (carotid arteries), kidneys (renal arteries), or limbs (peripheral arteries).
• Peripheral Arterial Disease (PAD): A condition where the blood vessels in the legs become narrowed or blocked, leading to poor circulation, leg pain, and potential complications such as non-healing wounds or ulcers.
• Carotid Artery Disease: A narrowing of the carotid arteries, which supply blood to the brain, increasing the risk of stroke.
• Renal Artery Stenosis: A narrowing of the arteries that supply the kidneys, potentially leading to high blood pressure or kidney damage.
• Coronary Artery Disease: A buildup of plaque in the coronary arteries, which supply blood to the heart, potentially causing chest pain, shortness of breath, or heart attacks.
• By opening the narrowed vessel with a stent, vascular stenting improves blood flow, alleviates symptoms, and reduces the risk of more serious complications, such as tissue damage, strokes, or heart attacks.

Who is a Candidate for Vascular Stenting?

Ideal candidates for vascular stenting include individuals with narrowed or blocked arteries due to atherosclerosis or other vascular conditions. However, not everyone with vascular disease is a candidate for stenting. Several factors guide the decision to perform stenting, including:

• Location of the blockage: Specialists typically use stenting for vessels that are narrowed or blocked but still accessible to a catheter.
• Severity of the blockage: Patients with moderate to severe blockages are often good candidates for stenting.
• Overall health: Candidates should be in good general health, with no contraindications to the procedure, such as severe kidney disease or active infections.
• Symptoms: Candidates typically experience symptoms such as leg pain, difficulty breathing, or chest pain, which reduced blood flow in the affected vessel causes.
• Failure of other treatments: Specialists often consider stenting when other treatments, such as medication or lifestyle changes, have not adequately improved symptoms.
• A comprehensive evaluation by an interventional radiologist is necessary to determine whether vascular stenting is the best treatment option based on the individual’s condition and overall health.

How Does Vascular Stenting Work?

The vascular stenting procedure is minimally invasive and specialists typically perform it under local anesthesia and mild sedation. Here is what you can expect:

• Preparation: You will lie on an examination table, and the area where the catheter will be inserted (usually the groin or wrist) will be cleaned and numbed with a local anesthetic. A mild sedative may be given to help you relax during the procedure.
• Catheter Insertion: The specialist makes a small incision at the access site (often the groin or wrist), and threads a catheter through the blood vessels to the site of the blockage. The specialist uses fluoroscopy (real-time X-ray) to guide the catheter to the correct location.
• Balloon Angioplasty (if needed): In some cases, the specialist may use a balloon catheter to inflate the blocked artery before placing the stent. The balloon helps to open up the artery and push the plaque to the sides, making room for the stent.
• Stent Placement: Once the specialist clears the blockage, they insert the stent through the catheter and position it at the site of the narrowing or blockage. The specialist then expands the stent, either by inflating a balloon or by using a self-expanding stent, to hold the artery open.
• Completion: Once the stent is securely in place, the specialist removes the catheter. The specialist closes the small incision site with pressure and applies a bandage. The procedure usually takes about 1 to 2 hours, depending on the complexity.
• Most patients are able to go home the same day or after a short observation period in the recovery area.

What to Expect After Vascular Stenting

After the procedure, the care team will monitor you for a few hours to ensure there are no immediate complications. Here’s what you can expect after vascular stenting:

• Recovery time: Most patients are able to go home the same day or the following morning, depending on the complexity of the procedure.
• Post-procedure care: The care team may advise you to rest for the first 24 to 48 hours after the procedure, avoiding strenuous activities such as lifting heavy objects or exercising.
• Follow-up visits: The care team will schedule follow-up appointments to monitor the effectiveness of the stent and ensure that the artery remains open. This typically involves imaging tests such as ultrasound or angiography to check the stent’s placement and patency (openness).
• Medications: After stenting, the specialist may prescribe medications such as blood thinners to patients (antiplatelet or anticoagulant drugs) to prevent blood clots from forming around the stent. It’s important to take these medications as prescribed.
• Most patients experience significant symptom relief after stenting, including reduced pain, improved circulation, and a decreased risk of serious complications like heart attacks or strokes.

Benefits of Vascular Stenting

Vascular stenting offers numerous advantages over traditional surgery:

• Minimally invasive: Vascular stenting does not require large incisions or major surgery, making it less invasive than alternatives like bypass surgery or open artery surgery.
• Quick recovery: Most patients recover quickly and can return to their normal activities within a few days to weeks, with minimal pain and discomfort.
• Reduced risk of complications: Compared to traditional surgery, stenting carries a lower risk of infection, bleeding, and other complications.
• Preserves the vessel: Stenting can preserve the affected blood vessel, ensuring that the vessel remains functional and reducing the need for more extensive surgeries.
• Effective and long-lasting: Vascular stenting is a proven treatment that can provide long-term relief from symptoms and improve circulation.

Risks and Complications

While vascular stenting is generally safe and effective, as with any medical procedure, there are some risks and potential complications, including:

• Blood clots: Although rare, blood clots can form around the stent, potentially leading to re-narrowing of the artery or a stroke or heart attack.
• Infection: There is a small risk of infection at the catheter insertion site or within the blood vessels.
• Re-narrowing of the artery: In some cases, the artery may become narrow again after stent placement, a condition known as restenosis. This can sometimes require a repeat procedure.
• Damage to the blood vessel: The catheter or stent placement may cause damage to the blood vessel, leading to bleeding or other complications.
• Allergic reaction: Some patients may have an allergic reaction to the contrast dye used during the procedure, although this is uncommon.
• Your doctor will discuss these risks with you and help determine whether stenting is the right treatment option for your specific condition.

When to Consider Alternative Treatments

While vascular stenting is an excellent treatment option for many patients, it may not be appropriate for everyone. Other treatment options for blocked or narrowed blood vessels may include:

• Bypass surgery: A surgical procedure where a surgeon creates a new pathway around the blocked or narrowed vessel.
• Endarterectomy: A surgical procedure to remove plaque from the artery.
• Medications: Patients may use medications to help control symptoms and reduce plaque buildup, but they do not directly address the blockage.
• Your interventional radiologist or vascular surgeon will discuss these options with you based on your specific condition and health history.
