Pos us micrhpheres yog constressible hydrogel microspheres nrog cov duab tsis tu ncua, du los ua cov tshuaj kho mob ntawm polyvinyl cawv (pva) cov ntaub ntawv. Purnolic jearcheles muaj macromer muab tau los ntawm polyvinyl cawv (PVA), thiab yog-resigable, thiab muaj nyob hauv ntau yam ntawm cov ntau thiab tsawg. Kev tshuaj tiv thaiv yog 0.9% sodium vloride tov. Cov ntsiab lus dej ntawm tag nrho polymerized micymerized yog 91% ~ 94%. Jearchares tuaj yeem ua siab ntev compression ntawm 30%.
Cov emburbic tsom iav yog npaj los siv rau cov embolization ntawm cov qog ntshav (avps) thiab hypervascular qog, suav nrog uterine fibroids. Los thaiv cov ntshav rau lub hom phiaj, cov qog lossis malformation yog stinved ntawm cov as-ham thiab shrinks loj.
Hauv tsab xov xwm no, peb yuav qhia koj cov ncauj lus kom ntxaws txog kev yuav siv cov micron chophe.
Khoom npaj
Nws yog ib qho tsim nyog los npaj 1 20ml koob txhaj tshuaj, 2 lub khob sawb, kev phais mob, tshuaj xyuas kev phais, piv rau kev txhaj tshuaj.
Kauj ruam 1: Tshuaj Kho Mob Siv Tshuaj
Siv cov tshuaj kho mob tsis huv ntawm cov tshuaj kho mob thiab muab tshuaj kws kho mob siv tshuaj rau hauv lub khob.
Hom thiab ntau npaum ntawm cov tshuaj kho mob tshuaj nyob ntawm qhov xav tau kev soj ntsuam.
Siv dej rau kev txhaj tshuaj kom yaj siv tshuaj kho mob, thiab cov pom zoo xav tau ntau dua 20mg / ml.
AFTER cov tshuaj kho tshuaj tshuaj tau yaj tag li, kev siv tshuaj kho yeeb tshuaj tau muab rho tawm nrog 10ml syringe.
Kauj ruam 2: Extraction tshuaj-nqa cov embolic jookpheres
Embolized microlized tau shaken, ntxig rau hauv lub koob txhaj tshuaj rab koob kom sib npaug lub siab hauv lub raj mis,thiab rho tawm cov tshuaj thiab cov tsom iav ntawm lub taub hau hauv lub taub hau nrog 20ml koob txhaj tshuaj.
Cia cov koob txhaj tshuaj sawv ntsug rau 2-3 feeb, thiab tom qab lub microspheres khom, tus supernatant yog thawb tawm ntawm kev daws teeb meem.
Kauj ruam 3: Thauj cov tshuaj kho mob tshuaj rau hauv cov roj hmab micphpheres
Siv 3 txoj hauv kev nres kom txuas cov koob txhaj tshuaj nrog cov tshuaj tiv thaiv yeeb yaj kiab thiab cov tshuaj ntxuav tshuaj, them nyiaj rau kev sib txuas kom ruaj khov thiab khiav.
Thawb cov tshuaj kho mob syringer nrog ib sab tes, thiab rub lub koob txhaj tshuaj, thiab rub lub koob txhaj tshuaj, thiab rub lub koob txhaj tshuaj uas muaj cov embic muaj nrog lwm tes. Thaum kawg, tshuaj kho tshuaj thiab cov microsphere tau muab sib xyaw ua ke hauv 20ml koob txhaj tshuaj, thiab cia nws rau 30 feeb, nws yuav tsum txhua 5 feeb thaum lub sijhawm.
Kauj ruam 4: Ntxiv cov xov xwm sib piv
Tom qab lub tsom iav tau ntim nrog cov tshuaj kho mob rau 30 feeb, qhov ntim ntawm cov kev daws tau muab xam.
Ntxiv 1-1.2 lub sijhawm ntim ntawm tus neeg sawv cev ntawm peb txoj kev nres, co zoo thiab cia sawv ntsug li 5 feeb.
Kauj Ruam 5: Kev rub tawm yog siv hauv cov txheej txheem ntawm cov txheej txheem
Los ntawm peb txoj kev nres, txhaj txog 1mL ntawm microspheres rau hauv 1mL syringe.
Lub tsom iav tsom iav tau txhaj rau hauv cov microcatheter los ntawm pulsed txhaj.
Cov Ntawv Qhia Mloog:
Thov saib xyuas kev ua haujlwm zoo li qub.
Paub meej tias cov tshuaj kho tshuaj yog yaj ua ntej thauj cov tshuaj.
Cov concentration tshuaj yuav cuam tshuam cov kev thauj cov tshuaj uas tau txais, rov qab ua rau cov tshuaj adsorption tsis muaj tsawg dua 20mg / ml.
Tsuas yog cov dej tsis huv rau kev txhaj tshuaj lossis 5% kev txhaj tshuaj zoo nkauj yuav tsum tau siv los ua kom yaj siv tshuaj kho mob.
Tus nqi ntawm dexorubicin kev sib cais hauv dej tsis huv kom txhaj tshuaj tau nrawm dua 5% cov kua pleev zoo nkauj.
5% kev txhaj tshuaj zoo li roj hmab sai sai dua li cov dej tsis huv rau kev txhaj tshuaj.
Kev siv ntawm iOformol 350 raws li qhov nruab nrab sib piv tau muaj txiaj ntsig ntau dua rau kev ncua ntawm lub microspheres.
Thaum txhaj rau cov qog nqaij hlav los ntawm cov microcatheter, cov mem tes txhaj tshuaj yog siv, uas yog qhov ua tau zoo dua rau cov tsom iav ncua.
