An approach for the clearing of throat clogged arteries less invasive are all effective and safe as surgical treatment for the prevention of stroke in patients with high risk, proven in accordance with the largest comparison of the two methods.
STENT, flexible network used pipes open blocked blood vessels, prop is used to remove plaque, which coronary arteries clogged heart attacks. Recently, it has been the gold standard used to open blocked neck arteries, which remains properties to lead, but surgery called carotid endarterectomy.
The new study shows that "We have now two good options for patients", says researcher Wayne Clark, MD, Oregon Health & Science University.
Choosing at the age of the individual patient, health and the settings can get off, he tells WebMD.
Presented at the American Stroke Association (ASA) International Conference race, study shows that in the weeks after the procedure, patients stents suffered slightly more strokes, and patients, the operation undergone some more heart attacks had.
But on average 2.5 years later, "no, there was no significant difference between the two groups, the number of events," says Clark.
About 2% of patients in both groups suffered a heart attack or stroke, stroke or death - the lowest ever in a fluke of corrosion Stenting against surgery study, he said the negative effects.
Interestingly, patients of less than 70 years in the service of patients was released a little more stents, more Bénéficiés and more surgery, explains the most important researcher Thomas Brott, MD, the Jacksonville Mayo Clinic.
"Most of us think less invasive procedure the question would be better suited for older patients, but based on our data we have," he tells WebMD.
The study was conducted by the National Institute of neurological disorders and stroke with supplemental funding from stent maker Abbott vascular financed.
Stenting vs. surgery: European study found conflicting results
The results were announced, in a few hours only after that researchers who reported European inferior the Stenting surgery, when it comes to prevent the stroke.
These results, online published the journal Lancet, showed that patients, the stents subjected to higher stroke, heart attack or death than patients, the operation.
Ralph Sacco, MD from the University of Miami, the President of the American Heart Association, tells WebMD that patient selection could explain the different results.
The European study took only patients of whose neck symptoms such as rushing keeps the ears or vision caused, problems the North American study included patients with or without symptoms. The symptoms are presumably sicker and more benefits of the surgery, Sacco, said.
Also, the doctors, which the stent procedures in the study in North America more experienced, Brott, performed explains.
There are also differences in the way of stents used, Clark said. In the European study, doctors allowed, all stent approved, during North American all employees of Acculink carotid stent system by Abbott doctors.
Each year almost 800,000 Americans suffer, a stroke and nearly 140,000 die, the cause of the in fact leading the third death in the United States.
The new study, called the CREST, involved 2 502 patients to more than 100 American and Canadian hospitals. About half was half received surgery and Stents.
30 Days after, 4.1% of the patients of stent was an attack on 2.3% of patients in surgery. But 2.3% of the surgery had a heart attack, patients with 1.1% of the patients of stents.
A better quality of life of the restoration that patients had a stroke, said Brott reported patients who have suffered a heart attack.
2.5 Years later, died 2.0% of stenting patients or suffered a heart attack or an accident line vs 2.4% of patients in surgery, a small difference could be coincidental.
In the test of European 1, 8.5% of the patients of stent 713 patients had a vascular accident, death or heart attack in the first 30 days after the operation, compared with 5.2% of the Group of the surgery.
