Stents: What They Are, When You Need One, and How to Recover

If your doctor mentioned a stent and you felt a little lost, this page is for you. A stent is a tiny tube that keeps a narrowed or blocked blood vessel open so blood can flow. Doctors use them most often in heart arteries, but you can get stents in other places too, like legs, kidneys, or the bile duct. Knowing the basics helps you ask the right questions and feel more in control.

Types of stents

There are two main kinds of stents for blood vessels. Bare-metal stents are simple metal scaffolds that hold the artery open. Drug-eluting stents release medicine over weeks or months to lower the chance the artery narrows again. For non-blood-vessel uses, stents can be plastic or metal and are shaped for specific spots—ureteral stents help urine flow, while biliary stents keep bile ducts open. Your doctor will pick the type based on the problem, your health, and the chance of re-narrowing.

Stent placement is usually done with a minimally invasive procedure. For coronary stents, a cardiologist feeds a thin tube (catheter) through an artery in your wrist or groin to the blocked area, inflates a small balloon, and places the stent. Most people go home the same day or the next day, but more complex cases may need longer monitoring.

Recovery, meds, and warning signs

After a stent, you'll get clear instructions. Expect a short rest period and avoid heavy lifting for a few days. For coronary stents, doctors almost always prescribe dual antiplatelet therapy—usually aspirin plus another medicine like clopidogrel—for a set time. This reduces the risk of a dangerous clot forming inside the stent. Follow the exact schedule your doctor gives; stopping those meds early can be risky.

Watch for warning signs: sudden chest pain, shortness of breath, heavy bleeding from the access site, fever, or signs of infection. If any of those happen, call emergency services. Schedule follow-up visits and tests—your doctor might want a stress test, ultrasound, or blood checks to make sure the stent is working and your heart is stable.

Simple lifestyle changes make a big difference. Quit smoking, move regularly, eat foods that lower cholesterol, and keep blood pressure and diabetes under control. These steps lower the chance you’ll need another stent later.

Questions to ask before the procedure: why do I need this stent, what type will you use, how long will I need blood-thinning meds, and what are the risks in my case? Getting clear answers helps you prepare and makes recovery smoother.
