Stent News and Research

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.

PERSEUS clinical program comparing TAXUS Element Stent to prior-generation stents: 12-month results

Drug-eluting stents offer new hope to patients with critical limb ischemia

In the United States, more than 100,000 amputations are performed each year on individuals with critical limb ischemia, the most severe form of peripheral arterial disease (PAD). The number one priority in treating these patients is to re-establish blood flow to avoid limb amputation.

Vertebroplasty helps patients become better equipped to continue with treatment for multiple myeloma

Treating non-osteoporotic compression fractures in patients with multiple myeloma, a blood cancer, shows that the use of vertebroplasty-a minimally invasive treatment performed by interventional radiologists using imaging guidance that stabilizes collapsed vertebrae with the injection of medical-grade bone cement into the spine-results in a reduction of pain, medication usage and disability, according to researchers in the largest study of its kind at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

Vertebroplasty: Patient selection vital

Patient selection is key for vertebroplasty—a minimally invasive treatment performed by interventional radiologists in individuals with painful osteoporotic vertebral compression fractures that fail to respond to conventional medical therapy—to be effective and successful, according to a study of more than 1,500 persons who were followed over seven years. Additionally, collaboration between an interventional radiologist and other medical experts in treating a patient is imperative, say researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

High ABI may indicate risk for future heart attacks

The prevalence of abnormal ankle-brachial index (ABI) test results among individuals tested for peripheral arterial disease (PAD)—and who are not considered at high risk of a coronary heart event by Framingham-based risk factors—is high and provides another way to identify those who may be at risk for future heart attacks, say researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

Study questions frequency of heart angiograms

A recent study raises questions about the frequency of doctors' use of elective heart angiograms, which showed no disease in almost 40 percent of patients. BusinessWeek reports: "Doctors may be sending patients too quickly for elective angiograms to detect heart disease, exposing them to radiation and driving up U.S. health-care costs, a study suggests.
