Lub LavaTMkua embolic cov neeg ua hauj lwm nyob rau hauv interventional radiology yog siv nyob rau hauv ntau yam ntawm interventional radiology txheej txheem.Lava kua embolic agents yog siv los sau cov hlab ntsha txawv txav thiab nres cov ntshav khiav, kho AVM thiab hypervascular hauv hlwb. AVMs tuaj yeem kho nrog cov kua embolic los ntawm kev txhaj tshuaj rau hauv cov hlab ntsha uas pub cov kev sib txuas tsis zoo. Raws li cov kua embolic tus neeg sawv cev solidifies, nws thaiv cov hlab ntsha thiab tiv thaiv cov ntshav ntws mus rau AVM, uas txo cov kev pheej hmoo ntawm cov teeb meem.Ib qho ntawm cov yam ntxwv tseem ceeb ntawm Lava kua embolic cov neeg ua haujlwm yog lawv lub peev xwm los tswj tau meej thaum txhaj tshuaj. Qhov no yog vim Lava tau tsim los ua cov kua dej qeeb, uas tso cai rau kev ua kom zoo dua hauv cov txheej txheem embolization. Tsis tas li ntawd, Lava tuaj yeem ua pwm thiab ua kom zoo li qub thaum nws raug txhaj, kom nws ua raws li cov duab ntawm lub nkoj tau kho. Qhov no ua rau nws zoo tagnrho rau kev kho mob AVMs thiab lwm yam kev nyuaj.Lwm feature ntawm Lava yog nws stability thiab durability. Thaum nws tau txhaj tshuaj, Lava hardens rau hauv cov khoom hnyav, tsim kom muaj kev thaiv mus tas li hauv cov hlab ntsha tsom. Tsis zoo li lwm cov tshuaj embolic, LAVA tsis tawg thaum lub sijhawm, yog li tsis tas yuav rov kho dua.
Khoom nta
Cov kua dej embolic muaj ntau yam tshwj xeeb hauv kev cuam tshuam hluav taws xob. Nov yog qee qhov ntawm cov yam ntxwv tseem ceeb:
1. Tswj Kev Xa Khoom: Cov kua embolic tuaj yeem xa tuaj raws li kev tswj hwm los ntawm lub catheter mus rau hauv cov hlab ntsha tsom. Qhov no tso cai rau tus kws kho mob radiologist kom tswj tau tus nqi thiab qhov chaw ntawm tus neeg sawv cev embolic, ua kom muaj kev nyab xeeb thiab ua tau zoo ntawm cov txheej txheem.
2. Radiopacity: Cov kua embolic agents yog radiopaque, uas txhais tau hais tias lawv pom ntawm cov kev tshawb fawb imaging xws li X-rays, CT scans, thiab MRIs. Qhov no tso cai rau tus kws kho mob radiologist kom paub meej qhov tseeb qhov chaw ntawm tus neeg sawv cev embolic thiab saib xyuas nws cov teebmeem hauv lub sijhawm.
3. Qhov qis viscosity thiab siab diffusion coefficient ntawm Lava -12 tso cai rau nws nkag mus tob rau hauv cov ntaub so ntswg hypervascular, muab kev ua tiav tiav ntau dua li cov tshuaj ib txwm muaj.
4. Cov Khoom Tsis-Adhesive: Lava muaj kev pheej hmoo tsawg dua ntawm catheter entrapment, ua kom muaj kev nyab xeeb dua thiab txo qhov xav tau kev cuam tshuam ntxiv. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov txheej txheem nyuaj uas yuav tsum tau txhaj tshuaj ntau, vim lub sijhawm tshem tawm catheter txo qis, thiab lub sijhawm tag nrho ntawm cov txheej txheem yog luv.
5. Cov kua nplaum uas tsis yog nplaum embolic kuj tseem muaj peev xwm nkag mus tau zoo dua, ua rau lawv ncav cuag thiab occlude txawm tias qhov tsawg tshaj plaws ntawm cov hlab ntsha zoo.
