What are the indications for stenting?
Primary indications for stenting include failed angioplasty caused by a flow-limiting dissection or elastic recoil of the stenosis. The lumen of a stented segment will narrow somewhat over time due to pseudointimal proliferation. Therefore, stents work better in larger caliber arteries. However, recent studies have demonstrated that stents may also be useful for limb salvage in smaller vessels, and there is limited evidence that suggests that drug-eluting stents may further aid patency.
