Routine testing after aneurysm coiling carrie...( CINCINNATIA very low risk of complic...),Health

CINCINNATIA very low risk of complication is associated with a routine test that determines whether a brain aneurysm treated with endovascular coiling has started to recur, a study led by the University of Cincinnati Neuroscience Institute has shown.

The multi-site, retrospective study, published in the November issue of Neurosurgery, found a complication rate of 0.43 percent in 2,243 patients who had undergone cerebral angiography three months or more following endovascular treatment of a brain aneurysm. Of the 12 complications that occurred, only one was both major and permanent.

"Our study shows that the use of routine testing with angiography following endovascular treatment of brain aneurysms carries a very low risk of complication," says Andrew Ringer, MD, the study's lead investigator and director of endovascular neurosurgery at UC. "Because the risk is small, routine angiography should not be viewed as a deterrent to endovascular treatment of aneurysms."

A brain aneurysm is a balloon-like bulge or weakening of an arterial wall. If the walls of an aneurysm become too thin, it can rupture, often causing brain damage or death. Approximately 27,000 individuals suffer a ruptured brain aneurysm in the United States each year, according to the National Institute of Neurological Disorders and Stroke. Primary risk factors include smoking, hypertension and alcohol and drug abuse.

Specialists treat brain aneurysms in different ways. Some aneurysms are treated surgically through an opening in the skull or eyebrow. Neurosurgeons can place a clip on the aneurysm at its base, thereby blocking the blood flow into the aneurysm and preventing it from bleeding

If the aneurysm is not surgically accessible, endovascular specialists can reach it by threading a flexible catheter, which is capable of being steered, from the large femoral artery near the groin up to one of four arteries in the neck that lead to the brain. Us
