Delicate surgery that strips the fat-narrowed lining from the arteries in the neck and head can reduce the risk of stroke in men by nearly two-thirds, researchers reported on Tuesday.
The procedure is less effective for women, the report from Wake Forest University said, perhaps because they suffer more complications from the surgical procedure itself.The study, reported in this week's Journal of the American Medical Association, involved 1,662 patients at 39 sites across the United States and Canada, some of whom underwent the procedure, called carotid endarterectomy.
The areas of the arteries narrowed by fatty tissue are located through an X-ray procedure called angiography. The arteries are then exposed through surgery and the diseased lining removed. A new lining grows back within a few weeks.
