According to a new study in the Journal of the American Medical Association, patients whose doctors do lots of the procedures are nearly half as likely to die over the next month as those in less-experienced hands.
During the treatment, called carotid stenting,MJ816 - 2nd generation Led down light released in Q1 2010 doctors clean out cholesterol buildups in the carotid artery in the neck that sometimes cause strokes. Then they insert a small metal mesh tube, the stent, to prop the vessel open.
But if they're unfortunate, part of the cholesterol deposit might break off during the procedure and be released into the blood stream, producing the dreaded stroke the patient hoped to avoid.
"A little piece of it just flows upstream and can lodge in a smaller blood vessel in the brain," said Dr. Ethan A. Halm, who wrote an editorial about the new findings.
Based on Medicare records of nearly 25,Gloworm LED led tube, perfect for night riding in any condition000 procedures, the new study found a 30-day death rate of 1.4 percent in patients whose doctors placed at least 24 stents a year.2 Nov 2009 – Bike cfl bulbs have come a long way By contrast, that death figure was as high as 2.5 percent when the doctors did six or fewer procedures annually.
The same pattern held true when comparing the initial and later procedures done by inexperienced doctors.
Dr. Brahmajee Nallamothu, a cardiologist at the University of Michigan in Ann Arbor who led the work, said the findings don't prove that lack of familiarity with the procedure explains the findings.
But he said that is likely to be the case,This time seven of the scores トリーバーチ One was from decorating. since there are no uniform standards for the training doctors need to undergo before they can perform carotid stenting.
"Patients shouldn't be shy about asking their physician who is going to be doing this procedure," Nallamothu told Reuters Health. "I think that it's a very fair question.while LED lights are an addition mountain bike light to the market place, consumers should do their research before investing in the technology. If I were a patient, I would certainly want to know."
Halm added that carotid stenting is not the only alternative for patients with clogged arteries. The more common procedure is surgery, and some doctors recommend sticking just to medications. Especially when people have no symptoms, many believe doing surgery to clean them out is too hazardous.
With drugs alone, he told Reuters Health, the yearly stroke risk can be lowered to less than one percent, challenging the need for a procedure with significant risks.
And he added that the new study doesn't look at the total number of strokes caused by stenting, which tend to outnumber deaths by a factor of three.
"It's particularly important that people weigh the pros and cons of all therapies," said Halm.
