A detailed analysis of an earlier study which was published has suggested that for patients who have blockages in the carotid artery supplying blood to the brain, carotid artery stenting looks to be linked with an increased risk of both long-term and short-term adverse results in comparison to surgical treatments.

The results of a study which was published in the Journal of the American Medical Association’s Archives of Neurology came to the final conclusion that the process of stenting causes to a rise in the rate of risks involved, however they also have some benefits as compared to surgery to prevent cardiac arrests.

The process of using stents has now become a very in-use substitute to surgery for the treatment of carotid artery blockages. This artery is responsible for supplying blood to the brain. The safety of this procedure, however, is still a topic of debate.

Researchers found that during the initial one month the stenting of the carotid artery was linked to a 65 percent rise in the risk of dying with a stroke along with a 67 percent rise in the risk of any stroke.
