What can go wrong after a stent?
The nearby blood vessels may also get damaged due to the catheter. Blood clotting – A blood clot is the most serious complication that can occur within the stent. Blood clots can lead to severe complications such as heart attack, stroke, and thromboembolism to another part of the body.
Can a stent be placed incorrectly?
Stent mispositioning is associated with significantly higher restenosis and clinically driven TLR compared to patients with accurate stent placement.
What are the complications of a stent?
The risks associated with stenting include:
- an allergic reaction to medications or dyes used in the procedure.
- breathing problems due to anesthesia or using a stent in the bronchi.
- bleeding.
- a blockage of the artery.
- blood clots.
- a heart attack.
- an infection of the vessel.
- kidney stones due to using a stent in the ureters.
What causes a stent to fail?
Failure to deliver the stent to the lesion site was the main cause in 139 patients (92%) and failure either to expand adequately the stent or premature disengagement of the stent from the balloon in only 12 patients (8%). Peripheral stent embolization occurred in 10 (0.3%) patients.
What can cause a stent to collapse?
Immediate stent collapse can be caused by vascular spasm [5] and elastic recoil of the vessel [6].
What happens if a stent moves?
Can the stent move? Once the stent is opened and presses into the inside wall of your coronary artery, it will remain in place permanently. Vessel tissue will grow around the stent and hold it in place.
How do you fix restenosis?
Treatment of restenosis Restenosis in an artery without a stent is usually treated with balloon angioplasty and DES placement. ISR is usually treated with the insertion of another stent (usually a DES) or angioplasty using a balloon. The balloon is coated with medication used on a DES to inhibit tissue growth.
Do stents set off metal detectors?
Because the stent is a foreign object in your coronary artery, you should receive a stent card that describes the type, date and location of the stent. You will not set off any metal detectors after stent implantation.
