Clot nets help stroke recovery
Using small nets to extract blood clots from patients' brains may be the future of stroke care, according to two studies published in the Lancet medical journal. Clots block blood vessels, starving parts of the brain of oxygen, which leads to symptoms of stroke such as paralysis and loss of speech. The conventional clot-busting drugs only partially reopen 40% of large blocked arteries. These new devices partially reopen 70-90% of large blocked arteries. "These devices can be used in patients in whom it is not safe to give 'clot busting' drugs, patients who had recent surgery, and patients who are between 4.5 to eight hours after stroke onset", says researchers.
