Cov khoom siv me me-redirecting endoluminal, tseem hu ua FREDs, yog qhov ua ntej loj tom ntej hauv kev kho mob aneurysms.
FRED, luv luv rau endoluminal flow redirecting ntaus ntawv, yog ob txheejnpib tsib xee-titanium hlau mesh raj tsim los coj cov ntshav ntws los ntawm lub hlwb aneurysm.
Lub paj hlwb aneurysm tshwm sim thaum ib feem tsis muaj zog ntawm cov hlab ntsha phab ntsa swells, tsim cov hlab ntshav. Sab laug tsis kho, qhov dej ntws los yog ruptured aneurysm zoo li lub sij hawm foob pob uas tuaj yeem ua rau mob stroke, hlwb puas, coma, thiab tuag.
Feem ntau, cov kws phais neeg kho mob aneurysms nrog cov txheej txheem hu ua endovascular coil. Cov kws phais mob ntxig ib lub microcatheter los ntawm ib qho me me hauv cov hlab ntsha femoral nyob rau hauv lub puab tsaig, kis nws mus rau lub hlwb, thiab coil lub hnab ntawm lub aneurysm, tiv thaiv cov ntshav los ntawm lub aneurysm. Cov txheej txheem ua haujlwm zoo rau cov pob txha me me, 10 hli lossis tsawg dua, tab sis tsis yog rau cov pob txha loj dua.

Orlando Diaz, MD, tus kws kho mob neuroradiologist ntawm Houston Methodist Tsev Kho Mob tau hais tias "Thaum peb muab lub kauj rau hauv qhov me me, nws ua haujlwm zoo," said Orlando Diaz, MD, tus kws kho mob neuroradiologist ntawm Houston Methodist Tsev Kho Mob, qhov chaw uas nws tau coj FRED kev sim tshuaj, uas suav nrog cov neeg mob ntau dua li lwm lub tsev kho mob. tsev kho mob hauv teb chaws USA. Teb chaws USA. “Tab sis lub kauj tuaj yeem ua rau muaj qhov loj, loj heev. Nws tuaj yeem rov pib dua thiab tua tus neeg mob. "
Lub FRED system, tsim los ntawm lub tuam txhab kho mob MicroVention, redirects ntshav ntws ntawm qhov chaw ntawm aneurysm. Cov kws phais mob ntxig cov cuab yeej los ntawm microcatheter thiab muab tso rau ntawm lub hauv paus ntawm qhov aneurysm yam tsis tau kov lub aneurysmal hnab. Raws li cov cuab yeej raug thawb tawm ntawm lub catheter, nws nthuav dav los ua ib lub coiled mesh raj.
Es tsis txhob occluding lub aneurysm, FRED tam sim ntawd nres cov ntshav ntws nyob rau hauv lub aneurysmal hnab los ntawm 35%.
Diaz tau hais tias "Qhov no hloov pauv hemodynamics, uas ua rau cov hlab ntsha qhuav tawm," Diaz hais. “Tom qab rau lub hlis, nws thiaj li qhuav thiab tuag ntawm nws tus kheej. Cuaj caum feem pua ​​ntawm cov aneurysms ploj mus. "
Thaum lub sij hawm, cov ntaub so ntswg nyob ib ncig ntawm lub cuab yeej loj hlob thiab occludes lub aneurysm, zoo tsim ib tug tshiab kho cov hlab ntsha.
