Embolic Microspheres yog cov microspheres hydrogel uas muaj cov duab zoo li qub, du, thiab qhov loj me, uas tau tsim los ntawm kev hloov kho tshuaj ntawm cov khoom siv polyvinyl cawv (PVA). Embolic Microspheres muaj cov macromer uas tau los ntawm polyvinyl cawv (PVA), thiab yog hydrophilic, tsis-resorbable, thiab muaj nyob rau hauv ntau qhov ntau thiab tsawg. Cov tshuaj khaws cia yog 0.9% sodium chloride kua. Cov dej hauv cov microsphere polymerized tag nrho yog 91% ~ 94%. Microspheres tuaj yeem tiv taus kev nias ntawm 30%.
Cov Embolic Microspheres yog siv los kho cov arteriovenous malformations (AVMs) thiab hypervascular tumors, suav nrog uterine fibroids. Los ntawm kev thaiv cov ntshav mus rau thaj chaw uas xav tau, qhov mob qog lossis malformation yuav tsis muaj cov as-ham thiab yuav me dua.
Hauv tsab xov xwm no, peb yuav qhia koj cov kauj ruam ntxaws txog kev siv Embolic Microspheres.
Kev npaj khoom
Yuav tsum npaj 1 lub koob txhaj tshuaj 20ml, 2 lub koob txhaj tshuaj 10ml, 3 lub koob txhaj tshuaj 1ml lossis 2ml, txiab phais peb txoj kev, khob huv, tshuaj kho mob chemotherapy, embolic microspheres, contrast media, thiab dej rau txhaj tshuaj.
Kauj Ruam 1: Kho cov tshuaj chemotherapy
Siv txiab phais kom qhib lub raj mis tshuaj kho mob thiab nchuav cov tshuaj kho mob rau hauv ib lub khob huv.
Hom tshuaj kho mob thiab qhov ntau npaum li cas nyob ntawm seb xav tau kev kho mob li cas.
Siv dej rau kev txhaj tshuaj kom yaj cov tshuaj chemotherapy, thiab qhov concentration pom zoo yog ntau dua 20mg / ml.
Atom qab cov tshuaj chemotherapeutic yaj tag, cov tshuaj chemotherapeutic tau rho tawm nrog 10ml koob txhaj tshuaj.
Kauj Ruam 2: Kev rho tawm cov microspheres embolic uas nqa tshuaj
Cov microspheres embolized tau raug co tag nrho, ntxig rau hauv lub koob txhaj tshuaj kom sib npaug qhov siab hauv lub raj mis,thiab rho tawm cov tshuaj thiab microspheres los ntawm lub raj mis cillin nrog lub koob txhaj tshuaj 20ml.
Cia lub koob txhaj tshuaj sawv ntsug li 2-3 feeb, thiab tom qab cov microspheres poob qis, cov supernatant raug thawb tawm ntawm cov tshuaj.
Kauj Ruam 3: Muab cov tshuaj Chemotherapeutic tso rau hauv Embolic Microspheres
Siv 3 txoj kev nres lub raj xa dej los txuas lub koob txhaj tshuaj nrog lub embolic microsphere thiab lub koob txhaj tshuaj nrog cov tshuaj chemotherapy, xyuam xim rau qhov kev sib txuas kom ruaj khov thiab qhov kev taw qhia ntws.
Siv ib sab tes thawb lub koob txhaj tshuaj chemotherapy, thiab siv lwm sab tes rub lub koob txhaj tshuaj uas muaj embolic microspheres. Thaum kawg, cov tshuaj chemotherapy thiab microsphere sib xyaw rau hauv lub koob txhaj tshuaj 20ml, co lub koob txhaj tshuaj kom zoo, thiab cia nws rau 30 feeb, co nws txhua 5 feeb thaum lub sijhawm ntawd.
Kauj Ruam 4: Ntxiv cov khoom siv sib piv
Tom qab cov microspheres tau muab cov tshuaj chemotherapeutic ntxiv rau 30 feeb, qhov ntim ntawm cov tshuaj tau raug suav.
Ntxiv 1-1.2 npaug ntawm qhov ntim ntawm cov tshuaj sib piv los ntawm peb txoj kev stopcock, co zoo thiab cia sawv rau 5 feeb.
Kauj Ruam 5: Microspheres siv rau hauv cov txheej txheem TACE
Los ntawm peb txoj kev stopcock, txhaj li ntawm 1ml ntawm microspheres rau hauv 1ml koob txhaj tshuaj.
Cov microspheres tau txhaj rau hauv microcatheter los ntawm kev txhaj tshuaj pulsed.
Cov lus qhia txog kev mloog:
Thov xyuas kom meej tias kev ua haujlwm aseptic.
Ua ntej muab cov tshuaj tso rau hauv, xyuas kom tseeb tias cov tshuaj chemotherapeutic yaj tag.
Qhov concentration ntawm cov tshuaj chemotherapy yuav cuam tshuam rau cov nyhuv ntawm kev thauj tshuaj, qhov concentration siab dua, qhov nrawm dua ntawm kev nqus, qhov concentration ntawm kev thauj tshuaj pom zoo tsis pub tsawg dua 20mg / ml.
Tsuas yog siv cov dej huv uas siv rau kev txhaj tshuaj lossis 5% glucose txhaj tshuaj xwb los yaj cov tshuaj kho mob qog noj ntshav.
Tus nqi ntawm doxorubicin yaj hauv dej huv rau kev txhaj tshuaj yog sai dua li 5% glucose txhaj tshuaj.
5% glucose txhaj tshuaj yaj pirarubicin sai dua li dej huv rau kev txhaj tshuaj.
Kev siv ioformol 350 ua cov tshuaj sib piv tau zoo dua rau kev ncua ntawm microspheres.
Thaum txhaj tshuaj rau hauv qhov mob los ntawm microcatheter, kev txhaj tshuaj pulse yog siv, uas yog qhov zoo dua rau microsphere suspension.
