Embolization yog cov txheej txheem siv los thaiv cov ntshav ntws mus rau qee qhov chaw hauv lub cev, feem ntau yog kev kho mob qog nqaij hlav, arteriovenous malformations. Nws koom nrog kev kho cov mob no los ntawm kev txhob txwm thaiv cov hlab ntsha uas muab cov pa oxygen thiab cov as-ham.
Ib txoj hauv kev ntawm embolization yog siv cov kua embolic agents. Cov neeg ua haujlwm no yog cov kua dej uas tau txhaj rau hauv cov hlab ntsha uas pub cov ntaub so ntswg uas muaj teeb meem, ua kom khov thiab thaiv cov ntshav ntws mus rau thaj tsam ntawd. Lawv muab ntau qhov zoo dua li cov tshuaj embolic, xws li cov coils lossis cov khoom, uas lawv tuaj yeem ua tau zoo dua lub hom phiaj thiab sau cov hlab ntsha cuam tshuam, thiab tseem tuaj yeem tswj tau meej txog qhov ntau npaum li cas txhaj thiab qhov twg nws txhaj.
Muaj ntau ntau hom kua embolic cov neeg ua haujlwm tam sim no siv, suav nrog polyvinyl cawv, cyanoacrylate, thiab Lava. Cov neeg sawv cev no txhua tus muaj cov khoom tshwj xeeb uas ua rau lawv tshwj xeeb haum rau kev siv sib txawv.
Piv txwv li, polyvinyl cawv cov khoom yog cov khoom me me uas tuaj yeem yooj yim txhaj rau hauv cov hlab ntsha. Thaum lawv mus txog thaj chaw lub hom phiaj, lawv nqus dej thiab nthuav dav, cuam tshuam cov ntshav ntws. Qhov no ua rau lawv zoo rau kev siv los kho cov qog, qhov chaw uas lawv tuaj yeem ua rau cov hlab ntsha me me uas muab cov kev loj hlob.
Cyanoacrylate yog lwm cov kua embolic tus neeg sawv cev uas feem ntau siv hauv cov txheej txheem embolization. Nws yog cov nplaum nplaum uas ua rau tawv tawv ntawm kev sib cuag nrog cov ntshav, ua rau nws zoo tagnrho rau kev siv los kho cov hlab ntsha txawv txav lossis aneurysms. Cov khoom nplaum ntawm cyanoacrylate tso cai rau nws ua kom ruaj khov rau cov phab ntsa ntawm cov hlab ntsha, zoo sealing tawm ntawm qhov txawv txav los yog cov ntaub so ntswg.
Cov kua embolic kawg yog Lava. Tus neeg sawv cev no yog cov kua polymer uas tau txhaj rau hauv cov hlab ntsha uas cuam tshuam, qhov twg nws nrawm nrawm thiab tsim cov khoom hnyav. Lava muaj ntau yam zoo dua li cov tshuaj embolic ib txwm muaj, nrog rau kev muaj peev xwm ntws tau yooj yim dua rau hauv cov hlab ntsha me me, uas ua rau cov hlab ntsha loj hlob tuaj. Nws kuj tseem tso cai rau kev tswj hwm ntau dua ntawm qhov ntws ntawm tus neeg sawv cev embolic, ua kom yooj yim rau lub hom phiaj tshwj xeeb thiab tsis txhob cuam tshuam cov hlab ntsha ib txwm muaj.
Cov kua dej embolic tuaj yeem muab ntau yam txiaj ntsig tshaj cov tshuaj embolic ib txwm muaj. Lawv feem ntau ua haujlwm zoo dua ntawm kev tsom thiab thaiv cov ntshav ntws mus rau cov chaw tshwj xeeb, thiab tuaj yeem tswj tau ntau dua thaum lub sijhawm ua haujlwm. Txawm hais tias lawv yuav tsis yog qhov kev xaiv zoo tshaj plaws rau txhua txoj kev embolization, lawv yog cov cuab yeej tseem ceeb hauv kev kho mob ntawm ntau yam mob. Raws li ib txwm muaj, cov neeg mob yuav tsum sab laj nrog lawv tus kws kho mob txhawm rau txiav txim siab seb cov kua embolic yog qhov kev xaiv zoo tshaj plaws rau lawv tus kheej li cas.
