Iyini i-Embolic Microspheres?

Izinkomba Zokusetshenziswa (Chaza)

I-Embolic Microsphereskuhloswe ukuthi kusetshenziselwe ukuhlanganisa i-arteriovenous malformations (AVMs) kanye nezimila ze-hypervascular, kuhlanganise ne-uterine fibroids.

 

Igama Elivamile noma Elivamile: I-Polyvinyl Alcohol Embolic Microspheres Classification

Igama: I-Vascular Embolization Device

Ukuhlukaniswa: Ikilasi II

Iphaneli: Inhliziyo

 

Incazelo Yedivayisi

 

Ama-Embolic Microspheres ama-microsphere e-hydrogel acindezelayo anomumo ojwayelekile, indawo ebushelelezi, nosayizi olinganisiwe, akhiwa ngenxa yokuguqulwa kwamakhemikhali ezintweni ze-polyvinyl alcohol (PVA). I-Embolic Microspheres iqukethe i-macromer ethathwe ku-polyvinyl alcohol (PVA), futhi ayi-hydrophilic, ayi-resorbable, futhi atholakala ngebanga losayizi. Isixazululo sokulondoloza yisisombululo se-sodium chloride esingu-0.9%. Okuqukethwe kwamanzi e-microsphere eyenziwe nge-polymerized ngokugcwele kungama-91% ~ 94%. Ama-Microsphere angakwazi ukubekezelela ukucindezelwa okungama-30%.

I-Embolic Microspheres inikezwa inyumba futhi ifakwe ezitsheni zengilazi ezivaliwe.

I-Embolic Microspheres ihloselwe ukusetshenziselwa ukuhlanganisa i-arteriovenous malformations (AVMs) kanye nezimila ze-hypervascular, kuhlanganise ne-uterine fibroids. Ngokuvimbela ukunikezwa kwegazi endaweni okuhlosiwe, isimila noma ukukhubazeka kulambile ngenxa yezakhi zomzimba futhi ziyancipha ngosayizi.

I-Embolic Microspheres ingalethwa ngama-microcatheter ajwayelekile ebangeni elingu-1.7- 4 Fr. Ngesikhathi sokusetshenziswa, i-Embolic Microspheres ixubene ne-nonionic ejenti yokungafani ukuze yenze isisombululo sokumiswa. Ama-Embolic Microspheres ahloselwe ukusetshenziswa kanye futhi ahlinzekwa ayinyumba futhi angeyona i-pyrogenic. Ukulungiselelwa kwedivayisi ye-Embolic Microsphere kuchazwe kuThebula 1 nakuThebula 2 ngezansi.

Phakathi kobubanzi obuhlukahlukene bosayizi be-Embolic Microspheres, ububanzi besayizi obungasetshenziswa ekuhlanganisweni kwe-uterine fibroid yi-500-700μm, 700-900μm kanye no-900-1200μm.
