Kev siv cov bore aspiration catheters tau hloov pauv kev tswj hwm ntawm mob stroke ischemic. Cov catheters no muaj kev xaiv tsawg kawg nkaus rau kev tshem tawm cov ntshav txhaws uas ua rau mob stroke, ua rau kev kho mob stroke sai thiab zoo dua. Nyob rau hauv tsab xov xwm no, peb yuav tshawb nrhiav daim ntawv thov ntawm cov bore aspiration catheters hauv kev tswj cov mob stroke ischemic.
Feem ntau ua rau mob stroke yog qhov txhaws hauv cov hlab ntsha uas muab lub hlwb nrog oxygen thiab cov as-ham. Qhov blockage no feem ntau tshwm sim los ntawm cov ntshav txhaws uas tsim nyob rau hauv cov hlab ntsha. Qhov blockage ntev dua, qhov kev puas tsuaj rau lub hlwb ntau dua. Qhov no yog vim li cas nws yog ib qho tseem ceeb kom tshem tawm cov clot kom sai li sai tau.
Loj bore aspiration catheters yog tsim los ua li ntawd. Lawv muab tso rau hauv cov hlab ntsha uas cuam tshuam thiab nce mus rau qhov chaw ntawm cov hlab ntsha. Thaum nyob ntawd, lub catheter yog siv los nqus cov hlab ntsha los ntawm cov hlab ntsha, rov ua kom cov ntshav ntws mus rau lub hlwb. Qhov no yog hu ua mechanical thrombectomy.
Mechanical thrombectomy yog ib qho kev kho mob zoo heev rau mob stroke ischemic. Cov kev tshawb fawb tau pom tias cov neeg mob uas tau txais cov txheej txheem no muaj qhov muaj txiaj ntsig zoo ntawm kev ua haujlwm ywj pheej thiab muaj kev pheej hmoo ntawm kev tuag tsawg dua li cov uas tau txais kev kho mob ib leeg. Qhov tseeb, American Heart Association pom zoo kom siv tshuab thrombectomy raws li kev kho mob nyiam rau cov neeg mob tsim nyog nrog mob ischemic stroke.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov bore aspiration catheters yog lawv lub peev xwm los kho cov ntshav ntws mus rau lub hlwb sai. Qee zaum, cov txheej txheem tuaj yeem ua tiav hauv tsawg li 30 feeb. Qhov no yog qhov sib piv rau cov qauv kev kho mob, uas tuaj yeem siv sijhawm ob peb teev kom siv tau. Cov ntshav rov qab sai dua, qhov kev puas tsuaj tsawg dua yog ua rau cov ntaub so ntswg ntawm lub hlwb, txhim kho tus neeg mob txoj kev pheej hmoo ntawm kev rov zoo tag nrho.
Lwm qhov zoo dua ntawm cov bore aspiration catheters yog lawv versatility. Lawv tuaj yeem siv tau rau ntau qhov xwm txheej sib txawv, suav nrog rau cov neeg mob uas tsis tsim nyog rau cov hlab ntsha thrombolysis, cov hlab ntsha loj lossis ze ze, thiab cov uas muaj cov qhab nia siab National Institutes of Health Stroke Scale (NIHSS). Qhov no tso cai rau ntau tus neeg mob kom tsim nyog rau kev kho mob thrombectomy, txhim kho kev kho mob stroke tag nrho.
Kev siv cov bore aspiration catheters kuj tau nthuav dav lub qhov rais kho rau mob ischemic stroke. Kev lig kev cai, mechanical thrombectomy tsuas yog ua tau hauv thawj 6 teev ntawm qhov tshwm sim tshwm sim. Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no tau pom tias cov txheej txheem tuaj yeem ua tiav mus txog 24 teev tom qab pib hauv cov neeg mob xaiv. Qhov no tso cai rau cov neeg mob ntau dua kom tau txais kev saib xyuas mob stroke zoo tshaj plaws, txawm tias cov neeg uas tsis tuaj yeem nthuav tawm hauv qhov kev kho mob ib txwm muaj.
Tag nrho cov nyob rau hauv tag nrho, daim ntawv thov ntawm loj bore aspiration catheters tau zoo heev txhim khu kev tswj ntawm mob ischemic stroke. Cov catheters no muaj qhov cuam tshuam me me, muaj txiaj ntsig zoo rau kev tshem cov ntshav txhaws, rov ua kom cov ntshav ntws mus rau lub hlwb, thiab txhim kho cov txiaj ntsig ntawm tus neeg mob. Nrog lawv cov kev ua tau zoo thiab nthuav dav kho qhov rai, ntau tus neeg mob tsim nyog rau kev kho mob thrombectomy dua li yav dhau los. Raws li peb txuas ntxiv txhim kho peb txoj kev nkag siab txog kev kho mob stroke, cov bore aspiration catheters yuav tsum tsis txhob ua lub luag haujlwm tseem ceeb hauv kev kho mob stroke.
