stentrestenose
Stentrestenosis, also known as in-stent restenosis, is a condition that occurs when a blood vessel that has been treated with a stent becomes narrowed again. A stent is a small mesh tube used to keep an artery open after angioplasty, a procedure that widens narrowed arteries. Stentrestenosis can happen due to various factors, including the buildup of plaque (atherosclerosis) on the stent, inflammation, or the formation of blood clots. This condition can lead to reduced blood flow to the affected area, potentially causing symptoms such as chest pain, shortness of breath, or leg pain.
The diagnosis of stentrestenosis typically involves imaging tests like angiography, which uses X-rays to visualize the
