O le a le Embolic Microspheres?

Fa'ailoga mo le Fa'aaogaina (Fa'amatala)

Embolic Microspheresua fa'amoemoe e fa'aoga mo le fa'amamaina o fa'ama'i fa'aletonu (AVMs) ma tumo hypervascular, e aofia ai fibroid uterine.

 

Igoa masani pe masani: Polyvinyl Alcohol Embolic Microspheres Fa'avasegaga

Igoa: Vascular Embolization Device

Fa'avasegaga: Vasega II

Vaega: Cardiovascular

 

Fa'amatalaga o Meafaigaluega

 

Embolic Microspheres o microspheres hydrogel compressible ma se foliga masani, lamolemole luga, ma calibrated tele, lea e faia o se taunuuga o suiga vailaau i luga o le polyvinyl alcohol (PVA) mea. Embolic Microspheres e aofia ai se macromer e maua mai le polyvinyl alcohol (PVA), ma e hydrophilic, e le mafai ona faʻaaogaina, ma e maua i le tele o lapopoa. Ole vaifofo fa'asao ole 0.9% ole vaifofo ole sodium chloride. Ole mea ole vai ole microsphere atoa polymerized e 91% ~ 94%. Microspheres e mafai ona faʻafeiloaʻi le faʻamalosi o le 30%.

Embolic Microspheres o lo'o tu'uina atu ma fa'aputu i totonu o fagu tioata fa'amaufa'ailoga.

Embolic Microspheres ua fa'amoemoe e fa'aoga mo le fa'atupuina o fa'aletonu o le arteriovenous (AVMs) ma tumo hypervascular, e aofia ai fibroids uterine. E ala i le polokaina o le sapalai o le toto i le vaega o loʻo taulaʻi i ai, o le tuma poʻo le faʻaleagaina ua matelaina i meaʻai ma faʻaitiitia le lapopoa.

Embolic Microspheres e mafai ona tu'uina atu e ala ile microcatheters masani ile 1.7-4 Fr range. I le taimi o le faʻaaogaina, Embolic Microspheres e faʻafefiloi ma se sui faʻatusatusa e le ninionic e fai ai se fofo faʻamalolo. Embolic Microspheres ua faʻamoemoe mo le faʻaoga tasi ma e tuʻuina atu i le vaʻaia ma le le pyrogenic. O faʻasologa o masini a le Embolic Microsphere o loʻo faʻamatalaina i le Table 1 ma le Table 2 i lalo.

Faatasi ai ma le tele o lapopoa tele o Embolic Microspheres, o le tele o laina e mafai ona faʻaaogaina mo le uterine fibroid embolization o le 500-700μm, 700-900μm ma le 900-1200μm.
