Cov tshuaj ua kua embolic tau siv ntau xyoo hauv kev kho mob arteriovenous malformations (AVMs). Txoj kev kho ib txwm muaj cuam tshuam nrog kev phais, uas ua rau muaj kev pheej hmoo loj thiab tsis tas yuav ua tiav. Cov tshuaj ua kua embolic tau dhau los ua qhov kev xaiv nrov vim lawv qhov cuam tshuam tsawg kawg nkaus, yooj yim ntawm kev siv, thiab ua haujlwm tau zoo. Daim ntawv no yog tsom los tshuaj xyuas cov kev kawm tsis ntev los no hauv cov kua embolic cov neeg ua haujlwm thiab lawv cov kev siv peev xwm hauv thaj tsam ntawm neurointervention.
Cov tshuaj ua kua embolic raug cais raws li lawv cov txheej txheem ntawm kev ua thiab muaj pes tsawg leeg. Feem ntau siv cov kua embolic yog cyanoacrylates, Lava, thiab kua nplaum. Cyanoacrylates yog ib hom ntawm cov nplaum uas polymerize thaum sib cuag nrog cov ntshav, tsim cov khoom embolic loj. Lava yog ib qho tsis-nplaum kua embolic tus neeg sawv cev uas polymerizes thaum sib cuag nrog ib tug aqueous tov, tsim ib tug khoom embolic loj. Cov kua nplaum yog ib hom nplaum uas tau qhib los ntawm qhov ua rau sab nraud thiab dhau los ua ib qho khoom embolic loj thaum sib cuag nrog cov ntshav.
Vim muaj qhov tsis zoo ntawm cov tshuaj ua kua embolic, xws li qhov nyuaj ntawm kev tswj cov qib ntawm polymerization thiab xav tau cov cuab yeej tshwj xeeb, tau muaj kev tsom mus rau kev tsim cov kua embolic tshiab uas kov yeej cov kev txwv no. Qee qhov kev nce qib hauv qhov no yog:
1. Prepolymerized Liquid Embolic Agents: Prepolymerized kua embolic agents tau tsim los txo cov txheej txheem nyuaj. Hom kua embolic tus neeg sawv cev no twb tau pom zoo rau kev kho mob hauv Tebchaws Europe. Prepolymerized kua embolic cov neeg ua haujlwm muaj peev xwm txo tau cov sijhawm ua haujlwm, txhim kho kev nyab xeeb, thiab txo qhov xav tau ntawm cov cuab yeej tshwj xeeb.
2. Radiopaque Liquid Embolic Agents: Radiopaque kua embolic agents tau txhim kho qhov pom kev zoo piv rau cov tshuaj ua kua embolic. Kev muaj peev xwm ua kom pom cov khoom siv embolic tso cai rau kev soj ntsuam zoo dua ntawm kev ua tiav ntawm cov txheej txheem thiab cov teeb meem tshwm sim.
3. Biocompatible Liquid Embolic Agents: Biocompatible kua embolic agents tau tsim los txhim kho kev nyab xeeb thiab txo qhov kev pheej hmoo ntawm kev tsis zoo. Cov tshuaj embolic no tau txhim kho biocompatibility zog, txo qhov kev pheej hmoo ntawm o thiab lwm yam kev phiv.
Cov kev siv tau ntawm cov kua embolic cov neeg ua haujlwm hauv neurointervention yog qhov loj thiab ntau yam. Qee qhov kev kho mob feem ntau siv cov kua embolic yog:
1. Arteriovenous Malformations (AVMs): Cov kua dej embolic yog ib txoj hauv kev zoo rau kev phais kho AVMs. Lawv tau pom tias txo qis qhov loj ntawm AVMs thiab tseem txhim kho cov txiaj ntsig ntawm tus neeg mob.
2. Aneurysms: Cov kua dej embolic yog ib qho kev xaiv nrov rau kev kho mob aneurysms tsis zoo, tshwj xeeb tshaj yog rau cov neeg mob uas tsis zoo rau kev phais. Lawv tau pom tias txo qhov loj ntawm aneurysms thiab tiv thaiv rupture.
3. Arteriovenous Fistulas: Cov kua embolic feem ntau yog siv los kho arteriovenous fistulas, ib qho mob uas muaj qhov txawv txav ntawm cov hlab ntsha thiab cov hlab ntsha. Lawv tau pom tias yuav txhim kho cov txiaj ntsig ntawm tus neeg mob thiab txo cov teeb meem.
Kev nce qib tsis ntev los no hauv cov kua embolic cov neeg ua haujlwm tau ua rau kev txhim kho cov tshuaj tshiab thiab txhim kho cov neeg ua haujlwm kom muaj kev nyab xeeb dua, siv tau zoo dua, thiab siv tau yooj yim dua. Cov kev siv peev xwm ntawm cov kua embolic cov neeg ua haujlwm hauv neurointervention yog qhov loj thiab ntau yam, ua rau lawv muaj txiaj ntsig zoo rau kev cuam tshuam kev phais. Raws li daim teb no txuas ntxiv mus, peb tuaj yeem cia siab tias yuav pom kev nce qib ntxiv hauv cov kua embolic cov neeg ua haujlwm thiab kev nthuav dav ntawm lawv cov ntawv thov hauv neurointervention.
