Osawonongeka Elastic Design Polyvinyl Alcohol Embolic Microspheres

Embolic Microspheres ndi ma compressible hydrogel microspheres okhala ndi mawonekedwe okhazikika, osalala pamwamba, ndi kukula kwake, omwe amapangidwa chifukwa cha kusintha kwa mankhwala pa zida za polyvinyl mowa (PVA). Embolic Microspheres imakhala ndi macromer yochokera ku polyvinyl alcohol (PVA), ndipo ndi hydrophilic, yosasinthika, ndipo imapezeka mosiyanasiyana. Njira yothetsera vutoli ndi 0.9% sodium chloride solution. Madzi okhala ndi polymerized microsphere ndi 91% ~ 94%. Ma Microspheres amatha kulekerera kupsinjika kwa 30%.
Ma Embolic Microspheres amaperekedwa osabala ndipo amapakidwa mu mbale zagalasi zomata.
Embolic Microspheres adapangidwa kuti azigwiritsidwa ntchito popanga ma arteriovenous malformations (AVMs) ndi zotupa za hypervascular, kuphatikiza uterine fibroids. Mwa kutsekereza magazi kudera lomwe mukufuna, chotupacho kapena cholakwikacho chimakhala ndi njala yazakudya ndikuchepa kukula.
Embolic Microspheres imatha kuperekedwa kudzera mu ma microcatheter wamba mumtundu wa 1.7-4 Fr. Panthawi yogwiritsira ntchito, Embolic Microspheres imasakanizidwa ndi chinthu chosiyana ndi nonionic kuti apange yankho loyimitsidwa. Embolic Microspheres amapangidwa kuti azigwiritsidwa ntchito kamodzi ndipo amaperekedwa osabala komanso osakhala pyrogenic. Kukonzekera kwa chipangizo cha Embolic Microsphere akufotokozedwa mu Table 1 ndi Table 2 pansipa.
Pakati pa kukula kosiyanasiyana kwa Embolic Microspheres, kukula kwake komwe kungagwiritsidwe ntchito popanga uterine fibroid embolization ndi 500-700μm, 700-900μm ndi 900-1200μm.
