Stents Risks 스텐트 위험율 #
After a stent insertion,
You may feel a bit of soreness at the incision site. Mild painkillers can treat this. Your doctor will probably prescribe anticoagulant medication to prevent clotting.
When you return home, drink plenty of fluids and restrict physical activity for some time.
Make sure to follow all of your doctor’s instructions.

Risk;;
About 1–2 percent of people who have stented arteries develop a blood clot at the stent site.
Blood clots can cause a heart attack, stroke, or other serious problems.
Risk of blood clots is greatest during first few months after the stent is placed in the artery.
Your doctor will likely recommend that you take aspirin and another anticlotting medicine, such as clopidogrel, for at least 1 month or up to a year or more after having a stent procedure. These medicines help prevent blood clots.
The length of time you need to take anticlotting medicines depends on the type of stent you have. Your doctor may recommend lifelong treatment with aspirin.
Stents coated with medicine may raise your risk of dangerous blood clots.
(These stents often are used to keep clogged heart arteries open.)
However, research hasn't proven that these stents increase the chances of having a heart attack or dying, if used as recommended.
Risks Related to Aortic Stents in the Abdomen,
Although rare, a few serious problems can occur when surgery or a fabric stent is used to repair an aneurysm in the abdominal aorta. These problems include:
- A burst artery (aneurysm rupture).
- Blocked blood flow to the stomach or lower body.
- Paralysis in the legs due to interruption of blood flow to the spinal cord. This problem is very rare.
Another possible problem is the fabric stent moving further down the aorta.
This sometimes happens years after the stent is first placed.
The stent movement may require a doctor to place another fabric stent in the area of the aneurysm.

Complications associated with inserting a stent;;
Any surgical procedure carries risks. Inserting a stent may require accessing arteries of the heart or brain. This leads to an increased risk of adverse effects.
Risks associated with stenting include :
- allergic reaction to medications or dyes used in the procedure
- breathing problems due to anesthesia or using a stent in the bronchi
- bleeding
- blockage of the artery
- blood clots
- heart attack
- infection of vessel
- kidney stones due to using a stent in the ureters
- re-narrowing of the artery
Rare side effects include strokes and seizures;;
Few complications have been reported with stents, but there’s a slight chance the body will reject the stent. This risk should be discussed with your doctor.
Stents have metal components, and some people are allergic or sensitive to metals.
Stent manufacturers recommend that if anyone has a sensitivity to metal, they should not receive a stent.
