Yintoni i-Embolic Microspheres?

Iimpawu zokusetyenziswa (Chaza)

Embolic Microsphereszenzelwe ukuba zisetyenziswe embolization of arteriovenous malformations (AVMs) kunye ne-hypervascular tumors, kubandakanywa ne-uterine fibroids.

 

Igama eliqhelekileyo okanye eliQhelekileyo: I-Polyvinyl Alcohol Embolic Microspheres Classification

Igama: Isixhobo seVascular Embolization

Ukuhlelwa: Udidi II

Iphaneli: Intliziyo

 

Inkcazo yesixhobo

 

I-Embolic Microspheres i-compressible hydrogel microspheres enemilo eqhelekileyo, indawo egudileyo, kunye nobukhulu obulinganisiweyo, obunjwe ngenxa yokuguqulwa kweekhemikhali kwizinto ze-polyvinyl alcohol (PVA). I-Embolic Microspheres iqulethe i-macromer evela kwi-polyvinyl alcohol (PVA), kwaye i-hydrophilic, i-non-resorbable, kwaye ifumaneka kuluhlu lweesayizi. Isisombululo sokugcina yi-0.9% yesisombululo se-sodium chloride. Isiqulatho samanzi se-polymerized microsphere ngokupheleleyo yi-91% ~ 94%. I-Microspheres inokunyamezela ukunyanzeliswa kwe-30%.

I-Embolic Microspheres zibonelelwa zinyumba kwaye zipakishwe kwiibhotile zeglasi ezitywiniweyo.

Ii-Microspheres ze-Embolic zenzelwe ukusetyenziselwa ukunyanzeliswa kwe-arteriovenous malformations (AVMs) kunye ne-hypervascular tumors, kuquka i-uterine fibroids. Ngokuthintela ukunikezelwa kwegazi kwindawo ekujoliswe kuyo, i-tumor okanye i-malformation ilambile izondlo kwaye iyancipha ngobukhulu.

I-Embolic Microspheres inokuhanjiswa ngee-microcatheters eziqhelekileyo kuluhlu lwe-1.7-4 Fr. Ngexesha lokusetyenziswa, i-Embolic Microspheres ixutywe kunye ne-agent engafaniyo ye-nonionic ukwenza isisombululo sokumiswa. Ii-Microspheres ze-Embolic zenzelwe ukusetyenziswa okukodwa kwaye zibonelelwa ngeenyumba kunye ne-non-pyrogenic. Ukucwangciswa kwesixhobo se-Embolic Microsphere kuchazwe kwiThebhile 1 kunye neThebhile 2 ngezantsi.

Phakathi kweentlobo ezahlukeneyo zobukhulu be-Embolic Microspheres, ububanzi besayizi obunokusetyenziswa kwi-uterine fibroid embolization yi-500-700μm, 700-900μm kunye ne-900-1200μm.
