The odds of suffer an intracerebral ( IC ) hemorrhage during your life-time ( 1 in 50 ) are almost as terrifying as the as the chances are that it will kill you ( 4 in 10 ) if it does happen . IC hemorrhages ( and the hydrops , or clot , they produce ) account for 11 percent of all strokes , and are far more likely to severely disenable you than the effects of a lesser ischaemic slash . But this clot - busting machine might just turn the odds in your favour .
The medical community generally agrees that take out 20 - 50 percentage of a coagulum can drastically improve a patient role ’s survivability , but that option occur at the cost of the voice of your brain that must be removed to get at any clot below its aerofoil . Plus , surgical teams conventionally had to open large holes in your skull just to get access in the first place , which of course of instruction lead to more serious infection . And by “ skull , ” we ’re also babble out the front , facey part of it . As such , medicine ’s best course of discussion is to simply wait and see what happens while dish out anti - inflammatories to reduce the intracranial pressing .
But simply hoping for the best is n’t good enough for a team of researchers from Vanderbilt University . lead by Assistant Professor Robert J. Webster III and Assistant Professor of Neurological Surgery Kyle Weaver , the team has rise a automatonlike surgical tool that will suck out the clot clean out of your nozzle .
“ Transnasal ” operating theater is nothing new ; the Egyptians used a variation of it when removing the genius of mummification candidates . By go through the sinus cavity , doctors can get to the braincase with far less hurt than conventional methods , but only a few surgeons in the world have manus steady enough for such a soft task .
Webster ’s system take in the shaky hands out of the equation wholly . His active cannula system work like this : First , doctor perform a CT scan of the patient ’s head word , nail the location of the clot . Then , based on that entropy , the leading surgeon will square up the good place to enter the skull and get at the clot while minimizing damage to the brain itself .
The surgical team will then set up the consistence of the twist , dubbed the flight system , immediately above the access hole that the team has drilled into the affected role ’s skull . The trajectory organisation tuck a yoke of cuddle tube less than 1/20th of an inch in diam through that hole .
The tubes themselves are quite cunning . The straightforward verboten sleeve spread over a series of inflexible , precisely curved interior tubes . By manipulating out these individual inner tubes , surgeons can navigate the tip of the twist around the inside of the skull . Once the tip of the outer tube hits the clot , it extend the inner tube into the mass , whereupon the sawbones soak the twist to a suction pump and hoover out the bloody pulp magazine .
“ The trickiest part of the operation comes after you have removed a substantial amount of the clot . External pressure can induce the edges of the coagulum to partially collapse making it hard to keep caterpillar tread of the coagulum ’s boundaries , ” say Webster in a press statement . Even so , the system has shown that it can access and remove more than 90 percent of simulated stock clots .
The gimmick is still far from achieving FDA approval but the team is already working to incorporate a more accurate ultrasound - based guidance system , as well as develop information processing system models of how gray-haired matter deforms under emphasis to better portend how the hem in tissue will respond during the procedure . In any case , it ’s probably better than the current method could ply in the best of billet . [ Vanderbilt University – Medscape Reference ]
