Kev kho mob thaum ntxov ntawm mob ischemic stroke ntawm cov nkoj uas loj heev ntawm lub nkoj loj, tab sis cov nyhuv tsawg kawg nkaus xwb, cov nyhuv kho mob feem ntau yog neeg pluag. Nrog rau kev txhim kho cov thev naus laus zis thev naus laus zis, cov neeg kho tshuab pov haum tau tshwm sim maj mam tshwm sim. Intracntomy stent yog ib qho kev sib tawg tseem ceeb.
Lub intracranial thrombecty stent yog raws ntawm tus kheej kev nthuav dav cov tswvyim tsim. Thaum siv, cov folding stent yog xa mus rau intracant sirbus site los ntawm ib tug microcatheter. Tom qab ncav lub hom phiaj chaw, tus muaj stent cia li nthuav tawm thiab qhib hauv cov hlab ntshav, thiab nws tus qauv Mesh tuaj yeem haum kom nruj nrog lub thrombus. Tom qab tos ntev, lub stent thiab thrombus yog tag nrho ua ke, thiab tom qab ntawd tus kheej tau rov qab ua ke, yog li ua tiav cov hlab ntsha recanalization thiab rov qab ntshav rau lub hlwb.
Thrombectomy stents feem ntau yog ua los ntawm cov ntaub ntawv nco xws li npib tsib xee-titanium alloy. Nickel-titanium alloy muaj cov biocompatibility zoo heev thiab tuaj yeem muaj nyob rau hauv tib neeg lub cev ib puag ncig, txo qhov tshwm sim ntawm kev ua xua thiab tsis lees paub. Nyob rau tib lub sijhawm, nws muaj cov duab puab cim nco txog lub zog. Nws tuaj yeem sib txuas rau hauv qhov me me ntawm qhov chaw kub me me rau kev thauj mus los yooj yim, thiab tuaj yeem rov qab kho dua tshiab, thiab tuaj yeem kho tau tias lub stent tuaj yeem qhib siab rau hauv cov hlab ntshav. Ntxiv rau, lub mesh loj thiab cov duab ntawm tus stent yog ua tib zoo tsim. Tus mesh tsim nyog yuav tsum muaj peev xwm ntes tau zoo li sai sai vim tias poob, thaum ua kom dhau los ntawm kev tsim txom cov hlab ntsha txhaws. Cov stents sib txawv uas muaj cov cwj pwm sib txawv hauv cov qauv tshuaj mesh. Ib co stents muaj meshes me dua thiab muaj peev xwm ua tau ntawm kev ntes me me tawg; Lwm tus muaj cov meshes loj dua thiab yog qhov tsim nyog rau loj dua thrombi.
Tus thrombectomy stent muaj ntau yam zoo. Piv nrog ib txwm entravenous thrombolysis, cov thrombectomy stent muaj cov ntshav ntau dua ntawm cov neeg mob luv luv thiab txo cov mob ischemic puas rau lub hlwb.
