Study: Stents as Good as Surgery at Keeping Neck Arteries Op


Feb. 1, 2012 -- A less invasive approach for clearing neck arteries of dangerous plaque works just as well as surgical treatment for most people at high risk of stroke, according to the largest comparison of the two procedures to date.

Ninety-four percent of patients' arteries remained open two years after undergoing either surgery or the less invasive procedure, which involved inserting a stent.

Stenting, in which flexible mesh tubes are used to prop open blocked blood vessels, is widely used to clear plaque-clogged heart arteries, which cause heart attacks. More recently, it began to be used to open blocked neck arteries that lead to strokes, but surgery in which the vessel is cut open and cleared out, called endarterectomy, remains the gold standard.

Previous findings from the study of more than 2,500 patients showed about 7% of patients had a stroke, heart attack, or died over a four-year period whether they underwent surgery or stenting.

"Even after these results were published, many doctors were reluctant to perform stenting of the carotid artery [the blood vessel running up the neck to the brain] as they worried about reblockage of the arteries," says researcher Brajesh K. Lal, MD, associate professor of vascular surgery at the University of Maryland School of Medicine in Baltimore.

"Now we have evidence of virtually no difference in reblockage rate between surgery and stenting at two years," Lal tells WebMD.

Factors such as patient age and preference, and reimbursement, may influence the decision of whether to undergo stenting or surgery, he says.

The study, presented here at the American Heart Association/American Stroke Association’s International Stroke Conference 2012, was funded by the National Institute of Neurological Disorders and Stroke with supplemental funding from stent maker Abbott Vascular.
