Diki inoyerera-inotungamira endoluminal zvishandiso, inozivikanwawo seFREDs, ndiyo inotevera kufambira mberi kukuru mukurapa aneurysms.
FRED, ipfupi kune endoluminal kuyerera redirecting mudziyo, ari maviri-layernickel-titanium waya mesh chubhu yakagadzirirwa kutungamira kuyerera kweropa kuburikidza neuropi aneurysm.
Aneurysm yeuropi inoitika apo chikamu chisina kusimba chemadziro etsinga chinozvimba, kuumba bundu rakazara neropa.Kukasarapwa, kubuda ropa kana kuti kuputika kweaneurysm kwakafanana nebhomba renguva rinogona kutungamirira kusitiroko, kukuvara kweuropi, pakoma, uye rufu.
Kazhinji, vanachiremba vanorapa aneurysms nemaitiro anonzi endovascular coil.Vanachiremba vanopinza microcatheter kuburikidza nekachekwa kadiki mutsinga yemukadzi mugiriro, voipfuudza kuuropi, uye vokoira saga retsinga, kudzivirira ropa kuyerera richipinda mutsinga.Iyo nzira inoshanda zvakanaka kune madiki aneurysms, 10 mm kana pasi, asi kwete kune yakakura aneurysms.

"Patinoisa coil mune diki aneurysm, inoshanda zvakanaka," akadaro Orlando Diaz, MD, anopindira neuroradiologist paHouston Methodist Hospital, kwaakatungamira FRED kiriniki yekuedza, iyo yaisanganisira varwere vakawanda kupfuura chero imwe chipatara.chipatara muUSA.USA.“Asi coil yacho inogona kuita mbichana mbichana kuita hombe, hofori yeaneurysm.Inogona kutangazve uye kuuraya murwere. ”
Iyo FRED system, yakagadziridzwa nekambani yekurapa michina MicroVention, inodzoreredza kuyerera kweropa panzvimbo yeaneurysm.Vanachiremba vanoisa mudziyo kuburikidza ne microcatheter uye woiisa pazasi peaneurysm pasina kubata zvakananga aneurysmal sac.Sezvo mudziyo unosundirwa kunze kwecatheter, unowedzera kuumba yakamoneredzwa mesh chubhu.
Panzvimbo yekuvharira aneurysm, FRED akabva amisa kubuda kweropa muaneurysmal sac ne35%.
"Izvi zvinoshandura hemodynamics, izvo zvinoita kuti aneurysm iome," akadaro Diaz.“Pashure pemwedzi mitanhatu, inopedzisira yasvava uye inofa yoga.Makumi mapfumbamwe muzana eaneurysms aenda. "
Nekufamba kwenguva, matishu akatenderedza mudziyo anokura uye anovhara aneurysm, achigadzira tsinga itsva yakagadziridzwa yeropa.
