In medicine, a stent is a tube or other device placed in the body to create a passage between two hollow spaces, and stenting is the placement of a stent.
What is a stent placement? A stent is a wire mesh stainless steel tube that holds an artery open and keeps it from closing again. It becomes a permanent part of your artery. Why is it necessary? Fatty deposits can block blood flow through arteries and cause pain. A piece may break off, form a clot, and cause a heart attack or stroke. A stent opens the blockage and keeps it open, which allows blood to flow smoothly. Good blood flow reduces pain and risks of clots forming. How is it done?
