Stents Can Treat - Not Just Prevent - Strokes, Suggests Early Research

SUNY Buffalo researchers are reporting preliminary results on 16 patients who received stents to treat their strokes as part of a single center Investigational Device Exemption (IDE) from the FDA, with Elad Levy, M.D., as the principal investigator. Stents were placed and opened blocked arteries in the brain in all patients (100 percent) and 11 patients (69 percent) had significant improvement in their stroke symptoms.

Clot-busting drugs only work about half of the time because the blockage can be sticky and adhere to the wall of the artery, making it difficult to break up, said Dr. Hopkins.

Researchers used computed tomography (CT) perfusion to determine if the use of a stent would be beneficial. "With CT perfusion we can tell if the brain is dead or alive," said Dr. Hopkins. "Some patients experience brain death within an hour; others can have a viable brain 24 hours after the stroke starts." In those cases, it may still be possible to place a stent.

Tiny cage-like cylinders, stents are placed minimally invasively by threading a small tube, or catheter, through the arteries to the site of the blockage. A tiny balloon is inflated to open up the blockage. A collapsed stent is then placed at the site, where it expands and acts like scaffolding to keep the artery open.

Considered to be the premier meeting on endovascular therapy, the International Symposium on Endovascular Therapy (ISET) is attended by more than 1,200 physicians, scientists, allied health professionals and industry professionals from around the world. The meeting pioneered the use of live cases to promote the multidisciplinary treatment of cardiac and vascular disease by endovascular means. ISET is presented by the Baptist Cardiac & Vascular Institute, Miami. ISET 2009 is taking place Jan. 18-22 near Miami Beach, Fla. For more informat
