Endovascular Stents: What It Is and What to Expect

What kind of doctor provides Endovascular Stents?
A cardiologist specializes in the heart and blood vessels and often places stents in the arteries of the heart. A vascular surgeon or an interventional radiologist may place stents in other arteries. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
An endovascular stent is a small mesh tube placed inside a blood vessel; "endovascular" means inside the vessel. It works like a tiny scaffold that holds the vessel open so blood can flow through. Most stents are metal; some are coated with a drug that helps prevent scar tissue from growing inside.
Why a doctor might recommend it
Arteries can narrow when a fatty substance called plaque builds up on their walls, a condition called atherosclerosis. This reduces blood flow to the heart, legs, kidneys, or brain. A stent props the artery open to improve blood flow. Stents can also support a weak spot in an artery wall called an aneurysm.
How to prepare
- Ask which regular medicines to keep taking, especially blood thinners.
- Tell the care team about all medicines, vitamins, and supplements you use.
- Mention allergies, especially to iodine, contrast dye, latex, or metals.
- Ask when to stop eating and drinking beforehand.
- Arrange for someone to drive you home.
What happens during it
The doctor numbs the area, usually the wrist or groin, and makes a small opening in the artery. A thin tube called a catheter is guided to the narrowed spot. The doctor may open the artery with a balloon, then place the stent, which expands to hold the vessel open. You are usually awake but given medicine to relax.
Recovery
Most people go home the same day or the next day. Keep the puncture site clean and avoid heavy lifting for a few days; many return to normal activities within a week. Your doctor will schedule follow-ups and may prescribe medicines to prevent clots.
Risks and side effects
Stent placement is generally safe, but risks include bleeding or bruising at the puncture site, blood clots in the stent, and renarrowing of the artery. Call your doctor right away if you have chest pain, bleeding, fever, or swelling.
Who performs it
Interventional cardiologists place most heart stents. Vascular surgeons and interventional radiologists place stents in arteries outside the heart.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works alongside insurance. Either can help with everyday heart care, such as managing medicines and lifestyle changes. They do not place stents; if you need one, they will refer you to a cardiologist and coordinate care.
Common questions
Does a stent cure heart disease?
No. A stent opens a blocked artery and often eases symptoms such as chest pain. It does not remove the underlying disease. Most people also need medicines and lifestyle changes.
Can I feel the stent in my body?
Most people cannot feel a stent once it is in place. It is small and becomes part of the vessel wall over time.
Will a stent set off airport security metal detectors?
Stents are small, and most do not trigger metal detectors. If one does, a note from your doctor can help explain it.
How long does a stent last?
Stents are meant to be permanent. Some arteries narrow again over time, so regular follow-up care matters.
