Intracranial aneurysms tuaj yeem txhais tau tias yog nyias-walled kheej kheej cov qauv tsim los ntawm sab nrauv nthuav dav / dilation ntawm ib qho tsis muaj zog ntawm phab ntsa arterial. Lawv feem ntau tshwm sim ntawm bifurcation ntawm cov hlab ntsha thiab tuaj yeem ua rau cov hlab ntsha puas tsuaj los ntawm compressing paj ntaub thiab rupturing thiab los ntshav.
Intracranial aneurysms yog lub ntsiab ua rau hemorrhagic stroke. Lawv feem ntau asymptomatic, tab sis cov mob hnyav tuaj yeem ua rau muaj kev cuam tshuam rau lub paj hlwb, subarachnoid hemorrhage, thiab vascular spasm. Qhov ntau thiab tsawg ntawm aneurysms feem ntau muab faib ua peb hom: me, loj, thiab loj. Txoj kab uas hla ntawm ib tug me me yog tsawg dua 10 hli, txoj kab uas hla ntawm ib tug loj yog 10 mus rau 20 hli, thiab lub loj loj yog ntau tshaj 20 hli.
Muaj ntau txoj kev kho mob rau kev phais mob intracranial aneurysm, qhov zoo tshaj plaws uas paub tias yog aneurysm clipping, aneurysm bypass, detachable coil embolization, stent-pab embolization, balloon-pab embolization, thiab lwm yam. Feem ntau, muaj ob txoj kev kho mob rau intracranial. Kev phais mob aneurysm: qhib kev phais thiab kev phais phais. Ob leeg zoo heev rau aneurysms. Qhov kev xaiv ntawm txoj kev yog nyob ntawm qhov kev sib tham zaum kawg ntawm tus kws kho mob thiab tus neeg mob.
Txoj kev loj hlob ntawm kev kho mob intracranial aneurysm muaj keeb kwm ntev. Los ntawm angiography nyob rau hauv 1927 mus rau ib ntus aneurysm occlusion nrog balloon catheter nyob rau hauv 1964, rau mechanical occlusion ntawm aneurysms nrog detachable balloon nyob rau hauv 1973, kom dawb coil embolization ntawm intracranial aneurysms nyob rau hauv 1985, mus rau detachable coil 19 embolization ntawm ceev ceev, ntawm detachable coil embolization ntawm intracranial aneurysms nyob rau hauv 1990.
Raws li tuaj yeem pom los ntawm lub sijhawm, kev txhim kho ntawm kev kho mob ntawm intracranial aneurysms yog qhov nrawm heev. Txhawm rau txhim kho kev nyab xeeb, raug thiab ntom embolization tus nqi ntawm detachable coil embolization, cov qauv tsim ntawm microcatheters thiab coils sib txawv yog cov qauv thiab txawv.
Neurosafe's Renova detachable coil system yog tsim los rau occlude lossis thaiv cov ntshav ntws hauv cov hlab ntsha thiab peripheral vascular txawv txav ntawm txoj hauv kev endovascular. Nws muaj tsib yam ntxwv hauv qab no:
1.Optimized duab
Thawj 1.5loops yog 25% me dua li qhov hais txog qhov nruab nrab ntawm lub kauj kab, txo kev pheej hmoo ntawm coil herniation; Qhib chaw tsim, tso cai rau concentric filling.
2.Proprietary instant mechanical detachment system los ntawm phau ntawv so; Shorter detachment cheeb tsam, zoo heev minimizes kick-rov qab microcatheter;Detachment tactile kev nkag siab thiab pom kev nkag siab duplex tawm tswv yim, txhim khu kev qha ntau dua.
3.Hybrid xa ncej nta ib qho yooj yim thiab pushability, du tus me nyuam.
4.Los ntawm thav duab kom tiav, ntau qib softness thiab ntau thiab tsawg yuav npog ntau yam.
5.Frame ruaj ntseg, sau uniformly thiab tiav los ntawm kev nrhiav voids nyob rau hauv lub aneurysm.
