Stent Therapy

Peripheral Arterial Disease (PAD)

Your doctor may recommend placing a stent to reopen your blocked artery. A stent is a small, expandable, mesh-like tube that supports the artery and helps to keep it open.

Implanting a stent does not require open surgery. The doctor inserts a catheter into an artery in your arm or leg, similar to the balloon angioplasty procedure. A specially designed catheter delivers the stent to the narrow area in the artery. The stent is expanded, flattening the plaque against the artery wall and holding the artery open with a mesh tube. The catheter used to deliver the stent is then removed, but the stent stays in your artery permanently to maintain healthy blood flow.


  • The stent scaffolds the artery open, improving blood flow.
  • You are awake for the procedure; general anaesthesia is not needed.
  • The hospital stay is usually brief.
  • You may be able to return to normal activities quickly.


  • The stent can occlude, causing reduced and/or no blood flow to the area.
  • The insertion site may bleed or become infected.
  • The artery may become blocked again (restenosis).
  • The stent could puncture the artery (Artery Perforation)
