There are treatments available to help protect some people from stroke. And a new study finds one option may be better than another. When the artery that provides blood to the brain becomes clogged with fatty tissue the risk of stroke goes up dramatically. This narrowing can be treated less invasively, using a stent, or surgically where the fatty tissue is cleared out.
A study in the journal Lancet Neurology found those treated with a stent were three times more likely to have severely narrowed arteries later on compared to those who had the surgery.
An editorial following the research questions whether the routine use of the non-surgical approach is justified.
