Ngā Porowhita Irahiko Waipiro Polyvinyl Hoahoa Ātete Kore-Pirau

Ko ngā Irahiko Embolic he irahiko hydrogel ka taea te pēhi, he āhua ōrite, he mata maeneene, he rahi kua whakaritea, i hangaia hei hua o te whakarerekētanga matū i runga i ngā rauemi polyvinyl alcohol (PVA). Ko ngā Irahiko Embolic he macromer i ahu mai i te polyvinyl alcohol (PVA), ā, he hydrophilic, kāore e mimiti, ā, e wātea ana i roto i ngā rahi rerekē. Ko te otinga tiaki he 0.9% te otinga konutai pūhaumāota. Ko te nui o te wai o te irahiko polymerized kua oti te polymerize he 91% ~ 94%. Ka taea e ngā irahiko te tu atu ki te pēhitanga o te 30%.
Ka tukuna ngā Embolic Microspheres he parakore, ā, ka takaihia ki roto i ngā ipu karāhe hiri.
Ko ngā Embolic Microspheres he mea hanga hei whakamahi mā te embolization o ngā arteriovenous malformations (AVMs) me ngā pukupuku hypervascular, tae atu ki ngā fibroids uterine. Mā te aukati i te rere o te toto ki te wāhi ūnga, ka kore he matūkai i te pukupuku, i te malformation rānei, ā, ka iti haere te rahi.
Ka taea te tuku i ngā Maikoropiko Embolic mā roto i ngā maikoropiko catheter noa i te awhe 1.7-4 Fr. I te wā e whakamahia ana, ka konatunatua ngā Maikoropiko Embolic ki tētahi kaihoko rerekē kore-ionic hei hanga i tētahi otinga whakatārewatanga. Ko ngā Maikoropiko Embolic he mea hanga mō te whakamahinga kotahi, ā, ka tukuna he parakore, kāore hoki e pupuhi. Kei te Ripanga 1 me te Ripanga 2 i raro nei ngā whirihoranga taputapu o te Maikoropiko Embolic.
I roto i ngā awhe rahi rerekē o ngā Embolic Microspheres, ko ngā awhe rahi ka taea te whakamahi mō te embolization fibroid uterine ko te 500-700μm, 700-900μm me te 900-1200μm.
