Cov ntshav txhaws yog qhov ua rau mob hnyav thiab tuag thoob ntiaj teb. Lawv tuaj yeem ua rau mob stroke, plawv nres, pulmonary embolism, thiab tob vein thrombosis, thiab lwm yam. Nyob rau hauv xyoo tas los no, muaj kev txhim kho tseem ceeb ntawm cov khoom siv los kho cov ntshav los kho cov mob no. Clot retrieval devices yog cov cuab yeej siv tsawg kawg nkaus uas pab txhawm rau tshem tawm cov ntshav txhaws los ntawm lub cev cov hlab ntsha. Qhov kev tshuaj xyuas no tsom mus rau qhov kev hloov pauv tsis ntev los no hauv cov khoom siv los kho cov hlab ntshav thiab lawv lub luag haujlwm hauv kev tswj hwm cov kab mob ntsig txog cov ntshav.
Thrombectomy yog cov txheej txheem ntau tshaj plaws rau kev tshem tawm cov ntshav txhaws, thiab cov khoom siv los kho cov ntshav txhaws ua lub luag haujlwm tseem ceeb hauv nws. Muaj ntau hom kev kho cov hlab ntsha tuaj yeem pab tshem tawm cov hlab ntsha ntawm cov hlab ntsha. Cov khoom siv sib txawv hauv kev tsim, kev nyuaj, thiab kev siv tshuab. Peb yam tseem ceeb ntawm cov khoom siv los kho cov ntshav muaj xws li nqus thrombectomy catheters, mechanical thrombectomy devices, thiab aspiration thrombectomy devices.
Aspiration thrombectomy catheters yog qhov yooj yim tshaj plaws los kho cov khoom siv muaj. Lawv siv phau ntawv los yog cov tshuab nqus dej kom tshem tawm cov hlab ntsha los ntawm vasculature. Mechanical thrombectomy devices, ntawm qhov tod tes, yog cov cuab yeej nyuaj dua nrog lub tshuab tswj lub cev muaj zog uas tsim kom muaj lub zog nqus. Lawv tau ua pov thawj tias muaj txiaj ntsig zoo dua li kev nqus thrombectomy catheters, thiab ntau zaus, lawv ua haujlwm sai dua. Lawv tuaj yeem siv los ua cov kab ke ib leeg lossis ua ke nrog lwm cov khoom siv thrombectomy.
Aspiration thrombectomy devices yog lwm chav kawm ntawm cov khoom siv los kho cov ntshav. Lawv muaj ntau lub catheter tsim uas tso cai rau cov extraction ntawm cov hlab ntsha los ntawm kev nqus ntawm cov hlab ntsha mus rau hauv lub cuab yeej. Aspiration thrombectomy li tuaj yeem yog ib leeg-lumen, dual-lumen, lossis tri-lumen, thiab lawv cov kev ua tau zoo sib txawv nrog tus tsim. Tsis ntev los no, flowNS, lub tshuab nqus dej tshiab, tau tsim kho uas siv lub tshuab catheter hloov tau nrog ntau lub qhov sab kom tso cai rau cov kua dej tas mus li thaum tshem cov hlab ntsha.
Sib nrug los ntawm kev tsim cov khoom siv los kho cov hlab ntshav, kuj tseem muaj kev nce qib hauv lawv cov thev naus laus zis, txhawm rau txhim kho lawv cov txiaj ntsig thiab kev siv tau. Piv txwv li, cov tuam txhab tsim khoom tau tsim cov khoom siv los kho cov hlab ntsha nrog lub zais pa catheter uas tso cai rau qhib cov hlab ntsha ntawm cov hlab ntsha ua ntej tshem tawm cov ntshav. Tsis tas li ntawd, cov thev naus laus zis siab heev tau ua kom pom lub sijhawm tiag tiag ntawm cov hlab ntsha thaum tshem tawm, uas ua rau muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Clot retrieval cov cuab yeej siv tau nce ntxiv hauv kev tswj hwm cov kab mob cuam tshuam vim yog lawv qhov cuam tshuam tsawg kawg nkaus thiab kev ua tiav siab. Piv txwv li, cov cuab yeej siv tshuab thrombectomy tau siv dav hauv kev tswj cov mob ischemic mob stroke, ntawm lwm yam mob uas cuam tshuam nrog. Cov kev tshawb fawb tsis ntev los no tau pom tias kev siv cov khoom siv los kho cov hlab ntshav hauv kev tswj hwm ntawm ischemic stroke ua rau muaj feem ntau dua ntawm kev ua tiav rov ua tiav thiab cov txiaj ntsig zoo dua rau cov neeg mob dua li cov kev kho mob ib txwm muaj.
Nyob rau hauv lub neej yav tom ntej, yuav muaj kev txhim kho txuas ntxiv ntawm cov khoom siv los kho cov ntshav txhawm rau txhawm rau txhim kho lawv cov txiaj ntsig thiab kev nyab xeeb. Nrog rau kev nce qib hauv thev naus laus zis, yuav muaj kev hloov pauv ntau dua hauv kev tsim cov khoom siv los kho cov hlab ntshav, ua rau cov cuab yeej siv tau zoo dua thiab muaj kev nyab xeeb dua rau kev tshem tawm cov ntshav. Tsis tas li ntawd, cov kev tshawb fawb soj ntsuam ntau ntxiv yuav raug tshawb nrhiav kev ua tau zoo ntawm cov cuab yeej no, nrog rau kev nthuav dav ntawm lawv cov kev siv rau lwm yam mob ntsig txog ntshav.
Hauv cov ntsiab lus, cov khoom siv los kho cov hlab ntshav tau hloov pauv kev tswj hwm ntawm cov kab mob ntsig txog ntshav, thiab kev nce qib tsis ntev los no tau ua rau cov cuab yeej siv tau zoo thiab muaj kev nyab xeeb dua rau kev tshem tawm cov ntshav. Kev txhim kho txuas ntxiv ntawm cov khoom siv los kho cov ntshav yuav ua rau muaj txiaj ntsig zoo dua rau cov neeg mob thiab txo qis qhov tshwm sim ntawm kev mob ntshav qab zib thiab kev tuag vim yog mob ntshav txhaws.
