Intravascular stenting is basically an interventional procedure that does not require major open surgery and is a level 4 procedure in surgical grading. The purpose of vascular stenting is mainly due to the lack of blood supply to organs due to narrowing of the lumen of blood vessels for various reasons, and the stent has the effect of expanding blood vessels, reducing wall retraction, and increasing blood supply. Currently, the most commonly used vascular stents are coronary stents and cerebrovascular stents. The method of stenting is interventional. Usually, a puncture is made at the radial artery or femoral artery, and then special catheters, guide wires, balloons, stents, etc. are inserted through the blood vessels to rebuild the blood flow of stenotic or blocked coronary arteries.
