Learn About Stent Placement

What is the definition of Stent Placement?

A stent is a tiny tube placed into a hollow structure in your body. This structure can be an artery, a vein, or another structure, such as the tube that carries urine (ureter). The stent holds the structure open.

What are the alternative names for Stent Placement?

Drug-eluting stents; Urinary or ureteral stents; Coronary stents

What happens during a Stent Placement?

When a stent is placed into the body, the procedure is called stenting. There are different kinds of stents. Most are made of a metal or plastic mesh-like material. However, stent grafts are made of fabric. They are used in larger arteries.

A coronary artery stent is a small, self-expanding, metal mesh tube. It is placed inside a coronary artery after balloon angioplasty. This stent prevents the artery from re-closing.

A drug-eluting stent is coated with a medicine. This medicine helps further prevent the arteries from re-closing. Like other coronary artery stents, it is left permanently in the artery.

Why would someone need a Stent Placement?

Most of the time, stents are used when arteries become narrow or blocked.

Stents are commonly used to treat the following conditions that result from blocked or damaged blood vessels:

  • Coronary heart disease (CHD) (angioplasty and stent placement - heart)
  • Peripheral artery disease (angioplasty and stent replacement - peripheral arteries)
  • Renal artery stenosis
  • Abdominal aortic aneurysm (aortic aneurysm repair - endovascular)
  • Carotid artery disease (carotid artery surgery)

Other reasons to use stents include:

  • Keeping open a blocked or damaged ureter (percutaneous urinary procedures)
  • Treating aneurysms, including thoracic aortic aneurysms
  • Keeping bile flowing in blocked bile ducts (biliary stricture)
  • Helping you breathe if you have a blockage in the airways
What are the risks?

Comparative Study Between Drug-Eluting Balloons and Mimetic Stents for Popliteal Artery Disease Treatment in Patients With Chronic Lower Limb Ischemia

Summary: More advanced and severe cases of chronic lower limb ischemia (the so-called critical lower limb ischemia) are painful and limiting conditions that impact on patients' quality of life. Until now, the available evidence for the femoropopliteal area only defines open surgery or endovascular treatment indications. However, the best strategy for endovascular procedures is still unclear. The popliteal ...
