The Risk Of Carotid Artery Stenting

The Risk Of Carotid Artery Stenting.
Placing stents in the neck arteries, to lean them charitable and help prevent strokes, may be too risky for older, sicker patients, a inexperienced study suggests. In fact, almost a third of Medicare patients who had stents placed in their neck (carotid) arteries died during an regular of two years of follow-up. "Death risks in older Medicare patients who underwent carotid artery stenting was very high," said be ahead researcher Dr Soko Setoguchi-Iwata, an helper professor of medicine at Harvard Medical School in Boston. Placing a stent in a carotid artery is a course to prevent strokes caused by the narrowing of the artery.

A stent is a micro mesh tube that is placed into an artery to keep blood flowing, in this casing to the brain. Although clinical trials have shown success with this procedure, this study looked at the performance in a real-world setting, the researchers explained. Previous studies have estimated that carotid artery stenting reduces the peril of stroke by 5 percent to 16 percent over five years, Setoguchi-Iwata said. But this scan suggests the real benefit is not as great.

The high death appraise is likely due to these patients' advanced age and other medical conditions, Setoguchi-Iwata said. "Another latent contributing factor is that the proficiency of the real-world providers of carotid stenting likely vary, whereas checking providers had to meet certain proficiency criteria". Setoguchi-Iwata doesn't know how these expiry rates compare with similar patients who didn't have the procedure.
