Jul 20, 2022 · These treatments allow blood to flow more freely through the artery. When the treated, opened artery closes up again, this is restenosis. In-stent restenosis is a blockage or narrowing that comes back in the portion of the coronary artery previously treated with a stent.

Restenosis is the recurrence of stenosis, a narrowing of a blood vessel, leading to restricted blood flow. Restenosis usually pertains to an artery or other large blood vessel that has become narrowed, received treatment to clear the blockage, and subsequently become re-narrowed.

Oct 17, 2019 · Restenosis is the reduction in the diameter of the vessel lumen after angioplasty. Despite advances in stent technology, restenosis continues to be the most frequent cause of target lesion failure following percutaneous coronary intervention (PCI).

Jan 22, 2019 · Restenosis is when a part of an artery that was previously treated for blockage becomes narrow again. We'll tell you about causes, treatment, and minimizing risk.

Jul 27, 2023 · Restenosis is a condition characterized by the re-narrowing or blockage of a blood vessel or a previously treated artery after a medical intervention such as angioplasty or stent placement. It is a common complication that can occur in …

In-stent restenosis (ISR) is characterized by progressive narrowing of a coronary lesion previously treated with a stent (1). ISR is a result of stent-induced mechanical injury to the arterial wall of the treated segment (2) (figure).

Restenosis is usually defined as a re-narrowing of the arterial lumen occurring after a vascular intervention intended to treat ischemic lesions.
