Stroke risk following carotid stenting elevated by re-inflating balloon

The risk of stroke and death can be duplicated by a common practice in the stent, new research has found.

Used to treat patients with blocked arteries in the neck, the stent is to prop open narrowed blood vessels with a mesh stent. A balloon is typically used to make room for the stent, and is usually re-inflate once it is in place.

blocked neck arteries or carotids are a condition known as carotid stenosis, which means said arteries suffer from a buildup of fatty deposits and calcium, causing them to become rigid. This in turn weakens their ability to carry oxygen-rich blood to the brain and causes the condition of a significant risk of stroke -. Hence the need for stenting Carotid

Published in the Journal of Vascular Surgery, the study showed that the practice of the vessel balloon once the mesh is in place can double the risk of death and stroke during and shortly after surgery.

The study’s lead author, Dr. Mahmoud Malas, associate professor of surgery at the School of Medicine, Johns Hopkins University, said: “balloon after placing the stent seems to cause the same complication is intended to prevent surgeons should avoid doing .. Period. ”

Researchers believe that high risk is caused by the balloon to push the stent in the vessel walls. This then disrupts the buildup of fatty plaque, causing it to splinter off. Once released, this plaque can then travel to the brain and cause a stroke.

To conduct their study, the researchers analyzed carotid stenting patients aged 19 to 89, who underwent the procedure in US hospitals between 2005 and 2014, using data from the Quality Initiative vascular. Patients took three groups :. There was no pre-stent balloon another balloon just after the stent, and the final group of combination therapy

They found that patients treated with the combined method were twice as likely to experience a stroke or die, although the overall risk of the procedure remains low despite these findings.
