London, Oct. 24 (Reuters): Tiny coils inserted into the brain through blood vessels can reduce the risk of death and improve the quality of life of people who have suffered a brain haemorrhage, researchers said.
Bleeding from a cerebral aneurysm, an abnormal ballooning of an artery wall in the brain, is fatal in many cases and those that survive are often disabled.
Surgeons normally stop the bleeding by opening up the skull and placing a clip on the aneurysm. But the results of an international trial involving more than 2,000 patients showed the coil technique was safer and reduced deaths and disability by almost a quarter compared to surgery.
“This trial really has produced a groundbreaking result that will change medical practice,” said Andrew Molyneux, of the Radcliffe Infirmary in Oxford, England, who headed the trial.
Doctors conducting the trial, which compared the two methods in patients in Europe, North America and Australia, stopped it early because of the results.
Many hospitals have now adopted the coil technique as the preferred method of treatment.
Molyneux said about 80-90 per cent of patients with an aneurysm could benefit from the coil treatment.
