Restenosis

(重定向自Coronary restenosis)
The phenomenon of vessel restenosis, an immune response to damaged tissue, is known to be a common adverse event and the Achilles heel of angioplasty and stenting. Reducing restenosis is one of the highest priorities in research and the development of new endovascular technologies. Restenosis rates of drug-eluting stents appear to be significantly lower than bare-metal stents, and research is underway to determine if drug-eluting balloons also improve restenosis outcomes.
Conceptual schematic illustrating effectiveness of endovascular interventions on lumen diameter to improve blood flow as represented by acute gain, late loss (restenosis), and net gain.

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 renarrowed. This is usually restenosis of an artery, or other blood vessel, or possibly a vessel within an organ.
