About 85 per­cent of strokes are is­chemic

The lat­est me­chan­i­cal de­vice is a stent re­triever. The de­vice is a self-ex­pand­ing mesh tube at­tached to a wire, which is guided through a catheter. The physi­cian in­serts the catheter in an artery in the groin and guides it through var­i­ous blood ves­sels up to the blood clot in the brain. The stent re­triever pushes the gelati­nous blood clot against the wall of the blood ves­sel, im­me­di­ately restor­ing blood flow. The stent re­triever then is used to grab the clot, which is pulled out when the physi­cian re­moves the catheter. This tech­nique is known as an en­dovas­cu­lar treat­ment. Dr. Biller said in­tra­venous tPA re­mains the first-line ther­apy for treat­ing ap­pro­pri­ate pa­tients with acute is­chemic strokes. “In care­fully se­lected pa­tients, en­dovas­cu­lar treat­ment with a stent re­triever can pro­vide ad­di­tional ben­e­fit,” Dr. Biller said. Af­ter re­view­ing re­sults of six re­cent ran­dom­ized clin­i­cal tri­als, the AHA/ASA ex­pert panel rec­om­mended en­dovas­cu­lar treat­ment for pa­tients who are at least 18 years old; have suf­fered an acute, se­vere is­chemic stroke; have a clot block­ing a large artery sup­ply­ing blood flow to the an­te­rior cir­cu­la­tion of the brain; and meet other cri­te­ria. The guide­lines say en­dovas­cu­lar treat­ment is quite ef­fec­tive if be­gun within six hours of the on­set of an acute is­chemic stroke.
