A stent is a small mesh tube that’s used to treat narrowed or weakened arteries in the body.

You may have a stent placed in an artery as part of a procedure called angioplasty (AN-jee-oh-plas-tee). Angioplasty can restore blood flow through narrowed or blocked arteries. Stents help prevent arteries from becoming narrowed or blocked again in the months or years after treatment with angioplasty. You may also have a stent placed in a weakened artery to improve blood flow and to help prevent the artery from bursting.

Stents are usually made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. Some stents are coated with medicines that are slowly and continuously released into the artery. These medicines help prevent the artery from becoming blocked again.

Overall incidence of stroke, heart attack and death similar in carotid endarterectomy and stenting procedures

The two major procedures for opening blocked neck arteries to restore blood flow to the brain proved similar in overall long-term safety and efficacy, but showed differences in stroke and heart attack in the weeks following the procedure, according to late-breaking science presented at the American Stroke Association's International Stroke Conference 2010.

Hospital Roundup: Recession takes toll on NY hospital, investigation of heart surgeries in Maryland and California's soaring fees

The New York Times: Harlem's North General hospital may fold. Despite "often successful" efforts by "Harlem's civic, political and religious leaders … to get more money and more state subsidies to keep it going," the hospital may not survive this period of general "economic malaise." The hospital serves many low-income and uninsured patients in addition to middle-income patients. A rehabilitation center operated by a city-run hospital appears to be eyeing its location for an expansion as hospital officials consider restructuring and linking up with partners (Hartocollis, 2/25).
