Intracranial aneurysm yog ib hom kab mob intracranial vascular. Vim muaj qhov txawv txav los yog kis tau raug mob, lub zos vascular phab ntsa puas tshwm sim. Nyob rau hauv qhov kev txiav txim ntawm hemodynamic load thiab lwm yam, qhov txawv txav maj mam nthuav.
Coil embolization yog qhov kev kho mob feem ntau siv rau intracranial aneurysms. Ntau cov ntaub ntawv kho mob ua pov thawj tias kwv yees li 94% ntawm qhov tsis sib haum xeeb tuaj yeem kho tau yooj yim coil embolization. Coil embolization feem ntau yog siv lub microcatheter xa cov kauj mus rau cov kab noj hniav aneurysm, thaiv cov hlab ntsha ntawm cov ntshav ncig, yog li occluding lub aneurysm. Txoj kev kho no suav nrog: yooj yim coil aneurysm embolization, stent-pab coil aneurysm embolization, thiab balloon-pab coil aneurysm embolization.
Lub kauj yog platinum-ua hlau hlau nrog ib qho kev ntxhib los mos. Thaum lub sijhawm ua haujlwm embolization, lub microcatheter tau muab tso rau hauv cov kab noj hniav aneurysm, thiab tom qab ntawd siv lub laub pas nrig los thawb lub kauj mus rau hauv cov kab noj hniav los ntawm microcatheter. Thaum lub kauj yog ruaj khov nyob rau hauv lub aneurysm, qhov kev sib txuas ntawm lub laub pas nrig thiab lub kauj yog tso tawm, lub laub pas nrig yog tshem tawm ntawm lub microcatheter, thiab ces lub kauj tom ntej yog npaj xa.
Lub mechanism ntawm kev txiav txim ntawm lub kauj yog mechanically sau lub aneurysm lub cev thiab induce thrombosis nyob rau hauv lub aneurysm, thaiv cov kev cuam tshuam ntawm cov ntshav txaus ntawm cov phab ntsa aneurysm, yog li txo qhov kev pheej hmoo ntawm intracranial aneurysm rupture thiab los ntshav. Coil embolization yog kho los ntawm txoj hauv kev intravascular, tsis txhob muaj kev pheej hmoo siab thiab lub sijhawm rov qab los ntev cuam tshuam nrog intracranial incision thiab craniotomy hauv kev phais ib txwm.
Yooj yim coil aneurysm embolization yuav tsum muaj kev txawj ntse thiab kev paub ntau ntxiv los xyuas kom meej qhov ua tau zoo ntawm embolization.
Stent-pab coil aneurysm embolization tsub kom qhov ruaj khov thiab tswj kev kho mob los ntawm kev qhia txog stents. Lub stent tuaj yeem muab tso rau hauv cov hlab ntsha los muab kev txhawb nqa ntxiv los tiv thaiv lub kauj los ntawm kev poob los yog tawm ntawm qhov aneurysm, txo qhov kev pheej hmoo ntawm kev rov los ntshav tom qab. Nyob rau tib lub sijhawm, stent-pab kev kho mob zoo dua tiv thaiv cov ntshav ntawm cov ntaub so ntswg nyob ib puag ncig thaum embolizing lub aneurysm.
Balloon-pab coil aneurysm embolization tseem hu ua balloon remodeling technology. Thaum lub sijhawm ua haujlwm, lub zais pa tau muab tso rau ntawm lub caj dab ntawm qhov aneurysm txhawm rau tiv thaiv kev ua haujlwm tsis zoo ntawm lub kauj, thiab lub kauj yog muab tso rau hauv lub hnab ntim quav los ntawm microcatheter, uas tuaj yeem ua kom lub coil filling ceev hauv lub hnab aneurysm siab dua. Nws lub ntsiab kom zoo dua yog tias nws tuaj yeem siv los ua ib ntus occlusion los tswj los ntshav thaum muaj kev sib tsoo aneurysm thaum phais.
