Embolic Microspheres sune microspheres hydrogel masu matsawa tare da siffa ta yau da kullun, daɗaɗaɗɗen wuri, da girman calibrated, waɗanda aka samo su sakamakon gyare-gyaren sinadarai akan kayan polyvinyl barasa (PVA). Embolic Microspheres sun ƙunshi macromer da aka samo daga polyvinyl barasa (PVA), kuma suna da hydrophilic, ba za a iya sake sakewa ba, kuma suna samuwa a cikin kewayon masu girma dabam. Maganin adanawa shine 0.9% maganin sodium chloride. Abubuwan da ke cikin ruwa na cikakken microsphere polymerized shine 91% ~ 94%. Microspheres na iya jure wa matsawa na 30%.

Embolic Microspheres ana kawo bakararre kuma an shirya su a cikin gilashin da aka rufe.

An yi nufin amfani da Microspheres na Embolic don ƙaddamar da ƙwayoyin cuta na arteriovenous (AVMs) da kuma ciwon hawan jini, ciki har da fibroids na mahaifa. Ta hanyar toshe isar da jini zuwa wurin da aka yi niyya, ƙwayar cuta ko rashin lafiya yana fama da yunwar abubuwan gina jiki kuma yana raguwa cikin girma.

Za a iya isar da Microspheres Embolic ta hanyar microcatheters na yau da kullun a cikin kewayon 1.7-4 Fr. A lokacin amfani, Embolic Microspheres an haxa su tare da wakili mai bambanci na nonionic don samar da maganin dakatarwa. Embolic Microspheres an yi niyya don amfani guda ɗaya kuma ana ba su bakararre da marasa pyrogenic. An kwatanta saitunan na'urar Embolic Microsphere a cikin Table 1 da Table 2 a ƙasa.

Daga cikin daban-daban size jeri na Embolic Microspheres, girman jeri da za a iya amfani da igiyar ciki fibroid embolisation ne 500-700μm, 700-900μm da 900-1200μm.
