O le ā le Embolic Microspheres?

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

O Mikosipela Embolicua faʻamoemoe e faʻaaogaina mo le faʻaosoina o arteriovenous malformations (AVMs) ma tumo hypervascular, e aofia ai fibroids uterine.

 

Igoa Masani po'o le Igoa Masani: Fa'avasegaga o Polyvinyl Alcohol Embolic Microspheres

Igoa: Meafaigaluega Fa'apipi'i Vascular

Fa'avasegaga: Vasega II

Vaega: Fa'ama'i o le fatu

 

Fa'amatalaga o le Masini

 

O Embolic Microspheres o ni hydrogel microspheres e mafai ona fa'apipi'i ma se foliga masani, foliga lamolemole, ma le tele ua fa'atulagaina, ia e fausia ona o le suiga fa'akemikolo i mea polyvinyl alcohol (PVA). O Embolic Microspheres e aofia ai se macromer e maua mai le polyvinyl alcohol (PVA), ma e hydrophilic, e le mafai ona mitiia, ma e maua i le tele o lapopo'a. O le vaila'au fa'asao o le 0.9% sodium chloride solution. O le aofa'i o le vai o le fully polymerized microsphere e 91% ~ 94%. E mafai e Microspheres ona tatalia le fa'apipi'iina e 30%.

O lo'o tu'uina atu Embolic Microspheres ua mama ma afifiina i totonu o fagu tioata ua fa'amaufa'ailogaina.

O Embolic Microspheres ua fa'amoemoe e fa'aoga mo le embolization o arteriovenous malformations (AVMs) ma hypervascular tumors, e aofia ai uterine fibroids. O le poloka o le tafe toto i le vaega o lo'o fa'atatau i ai, e leai ni mea'ai e maua mai i le tumo po'o le malformation ma fa'aitiitia ai lona tele.

E mafai ona tu'uina atu Embolic Microspheres e ala i microcatheters masani i le va o le 1.7-4 Fr. I le taimi e fa'aoga ai, e fa'afefiloi Embolic Microspheres ma se vaila'au fa'aeseese e le ionic e fai ai se vaila'au fa'asusu. O Embolic Microspheres ua fa'amoemoe mo le fa'aoga e tasi ma e tu'uina atu i se auala mama ma e le fa'ama'i. O fa'atulagaga o masini o Embolic Microsphere o lo'o fa'amatalaina i le Laulau 1 ma le Laulau 2 o lo'o i lalo.

I le tele eseese o le lapopo'a o Embolic Microspheres, o lapopo'a e mafai ona fa'aaogaina mo le uterine fibroid embolization e 500-700μm, 700-900μm ma le 900-1200μm.
