Just over half of subjects had some degree of clot migration following IV t-PA (53 n230). A 90-day modified Rankin Scale score 2 was considered a good outcome.
CLOT BUSTER FOR STROKE ACTIVATOR
Endovascular clot retrieval or intra-arterial thrombectomy is another treatment used to return blood flow to the brain, often in conjunction with thrombolysis. IV recombinant tissue plasminogen activator (tPA), also called clot-buster, is a thombolytic drug that works by dissolving a clot. If there was no change in proximal position, they assessed thrombus fragmentation determined by the presence of a new thrombus in a distal artery. This allows blood flow to return to the brain. rt-PA is a clot-busting drug that breaks down a blood clot. "It's all well and good if you live in Parkville but this treatment needs to be provided equitably to everybody and it can't be provided at every single hospital, it's just not possible, there aren't people to do it and it's too expensive," Professor Barber said. Thrombolysis is the process where rt-PA is administered. It is understood that the Royal Melbourne Hospital, Monash and the Austin Hospital are all able to administer the treatment to major stroke patients. Thrombolytics are enzymes that kick off the process of breaking down proteins (fibrins) that form clots. It requires specially trained radiologists, stroke doctors and anaesthetists to be ready to operate within six hours. But for every five people you treat with clot retrieval, one more will go home able to function as an independent person, and there is one less person who is left severely dependent," Professor Barber said, speaking before he addressed the Australian and New Zealand College of Anaesthetists annual meeting in Auckland on Sunday.īut the technique is resource intensive and must be performed soon after the stroke.
