Patients whose stroke-causing blood clots were removed with a corkscrew-like device improved an average of 81 percent, according to a five-year study. Stroke suffers who received other minimally invasive treatments improved from 32 percent to 60 percent.
(PRWEB) January 18, 2010 -- Although all minimally invasive stroke therapies are beneficial, results are most dramatic in sufferers treated with a corkscrew-like clot-removing device, suggests a five-year-study being presented at the 22nd annual International Symposium on Endovascular Therapy (ISET).
In the study of 76 stroke sufferers, those treated with the corkscrew-like device improved an average of 81 percent. Others, who received clot-busting drugs or a combination of therapies, improved 32 percent to 60 percent. All patients were treated at St. Joseph’s Hospital in Tampa, one of seven comprehensive stroke centers in Florida.
Another study being presented at ISET suggests stents can be used to treat stroke – just as they sometimes are used to treat heart attacks – often resulting in significant improvements in brain function. The study includes 20 patients treated at one of three centers: the State University of New York at Buffalo (SUNY), the University of Florida at Gainesville and Barrow Neurological Institute in Phoenix. Patients treated with stents experienced an average of 60 percent improvement in brain function.
Stroke is called a brain attack because oxygen and blood flow to part of the brain is cut off. Eighty three percent of all strokes are ischemic, meaning they are caused by a small clot that blocks an artery in the brain, stopping blood flow. (The other 17 percent of strokes are hemorrhagic, caused by bleeding in the brain.) If blood flow is not restored, impairment can result, including loss of brain function, speech, vision, movement (paralysis) and death. About 750,000 peop
