Considering the fact that strokes occur from sudden loss of consciousness that results when a rupture or occlusion of a blood vessel leads to lack of oxygen in the brain – thereby resulting to inability to use the limbs and parts of the body for any functional benefits; researchers have now found a way for patients with strokes to live normal lives again.
They have found out, after almost 30 years of failing at the task, that by directly removing large clots of blood blocking the blood vessels in the brain, that it is largely possible to save brain tissues that would have died and then reactivate them to make them functional again, giving the patient the potential to regain use of his limbs and become independent in life again.
Doctors have devised a type of stent, or tiny wire cage, which is attached to the end of a catheter. This is then inserted through the groin and threaded into an artery and through to the brain. As soon as the tip end of the catheter reaches the blood clot, the stent is opened and pushed against the clot until it grabs and snags at the clot, giving doctors the opportunity to withdraw the catheter and stent with the blood clot attached to it.
About 500 stroke patients were used to conduct this research, and 90% of them got the tPA – a drug that dissolves tiny clots of blood in the brain. One in 5 patients that had received tPA recovered from strokes and were able to be independent again, but 1 in 3 patients that had their blood clot removed recovered fully and took proper care of themselves following the cure of their strokes.
630,000 Americans develop strokes as a result of blood clots that block brain vessels; and in almost half of these cases, the blood clot is largely big in a large brain vessel, making the patients vulnerable to greater risks and potentially useless with themselves. But combining the use of tPA for treating patients and the new stent that directly removes blood clots in the brain, neurologists are elated that they stand a greater chance of improving the conditions of patients than with traditionally ineffective treatment methods.
This research was conducted in the Netherlands, and published in The New England Journal of Medicine.
