Embolic Microspheresyog compressible hydrogel microspheres nrog cov duab tsis tu ncua, du nto, thiab calibrated loj, uas yog tsim los ntawm kev hloov kho tshuaj ntawm polyvinyl cawv (PVA) cov ntaub ntawv. Embolic Microspheres muaj cov macromer muab 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 tov. Cov dej ntsiab lus ntawm tag nrho polymerized microsphere yog 91% ~ 94%. Microspheres tuaj yeem tiv taus compression ntawm 30%.

Embolic Microspheres tau muab cov khoom tsis muaj menyuam thiab ntim rau hauv cov iav kaw.

Embolic Microspheres yog npaj los siv rau embolization ntawm arteriovenous malformations (AVMs) thiab hypervascular hlav, nrog rau cov uterine fibroids. Los ntawm kev thaiv cov ntshav mus rau thaj tsam ntawm lub hom phiaj, cov qog los yog malformation yog tshaib plab ntawm cov as-ham thiab shrinks loj.

Embolic Microspheres tuaj yeem xa los ntawm cov microcatheters hauv 1.7- 4 Fr ntau. Thaum lub sij hawm siv, Embolic Microspheres yog tov nrog ib tug nonionic contrast tus neeg sawv cev los tsim ib tug ncua kev kawm ntawv. Embolic Microspheres yog npaj rau kev siv ib leeg thiab muab cov khoom tsis muaj menyuam thiab tsis yog pyrogenic. Cov cuab yeej teeb tsa ntawm Embolic Microsphere tau piav qhia hauv Table 1 thiab Table 2 hauv qab no.

Ntawm ntau qhov loj me ntawm Embolic Microspheres, qhov loj me uas tuaj yeem siv rau kev siv lub tsev menyuam fibroid embolization yog 500-700μm, 700-900μm thiab 900-1200μm.
