OVERVIEW
A stent is a tiny, metal tube that holds your artery open to allow blood to go through better. Your provider can put in a stent after doing an angioplasty, which pushes aside a collection of plaque inside your artery. Stents are permanent and can keep your artery from getting too narrow again. Other kinds of stents help keep airways or ducts open.
What is Stent?
A stent is a very small tube your healthcare provider can put inside your artery to keep it open. They perform stent placement after they move plaque (cholesterol and fat) out of the way. Think of it like crowd control for your artery. It helps your blood get through more easily.
Stents are tube-shaped devices that a provider expands inside your artery during stent placement. A coronary stent can be 8 to 48 millimeters (up to almost 2 inches) long and 2 to 5 mm (up to one-quarter inch) around. This is shorter than a large paper clip and between the diameter of a new crayon tip and a new pencil eraser. Other stents can be much larger.
A stent stays inside your artery permanently (except the dissolving kind of stent). They look like tiny fishing nets. Many stents are metal, but companies use other materials to make certain kinds of stents.
What is Stent Placement?
Stent placement is a minimally invasive procedure used to treat narrowed or blocked arteries caused by conditions like coronary artery disease. A stent is a small, mesh-like tube inserted into the artery to keep it open and restore normal blood flow.

Uses of Stent Placement
- Treating blocked coronary arteries due to plaque buildup.
- Preventing heart attacks in patients with acute coronary syndrome.
- Managing conditions like peripheral artery disease (PAD).
- Supporting arteries after angioplasty (balloon procedure).
Types of Stents
Why is a Stent Used?

Benefits of Stent Placement
- Restores blood flow and relieves symptoms like chest pain.
- Prevents heart attack and improves quality of life.
- Short recovery time compared to open-heart surgery.
Procedure Steps
- Preparation:
- Local anesthesia is used; the patient is awake during the procedure.
- A catheter is inserted through a blood vessel, often in the groin or wrist.
- Stent Placement:
- A balloon-tipped catheter with the stent is guided to the blocked artery.
- The balloon inflates, expanding the stent against the artery walls.
- Once the stent is in place, the balloon is deflated and removed.
- Post-Procedure Care:
- Blood-thinning medications are prescribed to prevent clots.
- Patients are monitored for a few hours to a day before discharge.
