Can stents cause inflammation?
However, recent evidence has demonstrated that the coronary stent may induce the appearance of Systemic Inflammatory Response Syndrome (SIRS) [1,2], where restenosis after stent implantation constitutes the earliest manifestation of an inflammatory reaction.
What is restenosis of stent?
Restenosis means that a section of blocked artery that was opened up with angioplasty or a stent has become narrowed again. There are many treatment options for patients who have restenosis after receiving a stent.
Why does stent thrombosis occur?
The primary factors contributing to stent thrombosis are inadequate stent deployment, incomplete stent apposition, residual stenosis, unrecognized dissection impairing blood flow, and noncompliance with dual antiplatelet therapy (DAPT). Noncompliance with DAPT is the most common cause of stent thrombosis.
Do stents cause blood clots?
Though stents are used to treat coronary artery disease (CAD) and its complications, including clots, stents themselves can also lead to clots. The presence of a foreign body, such as a stent, in constant contact with the blood may lead to clotting in some people.
What is the incidence of in stent restenosis?
The exact incidence of in-stent restenosis (ISR) is not easy to determine caused by different clinical, angiographic and operative factors. In the pre-stent era the occurrence of restenosis ranged between 32–55% of all angioplasties, and drop to successively 17–41% in the bare metal stents (BMS) era.
What does restenosis at the Cleveland Clinic mean?
Restenosis means that a section of blocked artery that was opened up with angioplasty or a stent has become narrowed again. Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission. We do not endorse non-Cleveland Clinic products or services.
What does restenosis mean in a blocked artery?
Restenosis means that a section of blocked artery that was opened up with angioplasty or a stent has become narrowed again.
How is brachytherapy used to treat in stent restenosis?
Patients with in-stent restenosis treated with brachytherapy have lower target vessel revascularisation rates, lower binary restenosis rates, and larger MLDs than control vessels, up to three years after the procedure (summarised in table 2). The effects of brachytherapy are evident at six months, but persist to three years.
