Stentbased

Stent-based therapy is a medical intervention used to treat various cardiovascular conditions, primarily to maintain or restore blood flow in arteries that have been narrowed or blocked by atherosclerosis. A stent is a small, mesh tube made of metal or biodegradable materials that is inserted into the artery to prop open the passageway. This procedure is often performed using angioplasty, where a balloon is used to flatten the plaque and then the stent is deployed to keep the artery open.

Stent-based therapy is commonly used to treat coronary artery disease, peripheral artery disease, and other conditions that affect blood flow. The procedure is typically performed on an outpatient basis, using fluoroscopy to guide the insertion of the stent. The stent can be bare-metal or drug-eluting, with the latter releasing medication to inhibit smooth muscle cell proliferation and reduce the risk of restenosis, which is the re-narrowing of the artery.

The benefits of stent-based therapy include improved blood flow, reduced symptoms of ischemia, and increased exercise tolerance. However, it is not without risks, including the potential for stent thrombosis, in-stent restenosis, and late stent thrombosis. Long-term outcomes are generally favorable, with many patients experiencing significant improvements in their quality of life.

Stent-based therapy is a valuable tool in the management of cardiovascular disease, offering a less invasive alternative to traditional surgical procedures. However, it is essential to weigh the benefits against the risks and consider individual patient factors when deciding on the most appropriate treatment.
