Ko nga taputapu endoluminal whakaheke rere iti, e mohiotia ana ko FREDs, ko te ahunga whakamua nui e whai ake nei mo te maimoatanga o te aneurysms.
Ko te FRED, he poto mo te taputapu whakawhiti rerenga endoluminal, he papa-ruanickel-titanium wire mesh ngongo i hangaia hei whakatika i te rere o te toto i roto i te aneurysm roro.
Ka puta te mate o te roro i te wa e pupuhi ana tetahi wahi ngoikore o te pakitara uaua, ka puta he pupuhi ki tonu i te toto.Ki te kore e rongoatia, he rite te aneurysm kua pakaru, kua pakaru ranei ki te poma taima ka pa ki te whiu, te pakaru o te roro, te koma me te mate.
I te nuinga o te waa, ka rongoa e nga taote nga mate aneurysms me te tikanga e kiia nei ko te coil endovascular.Ka kuhu e nga kaitoi he microcatheter na roto i te werohanga iti i roto i te uaua o te wahine i roto i te riu, ka tukuna ki te roro, ka kohia te peke o te aneurysm, kia kore ai e rere te toto ki roto i te aneurysm.He pai te tikanga mo nga aneurysms iti, 10 mm iti iho ranei, engari kaua mo nga aneurysms nui ake.

"I te wa e whakauruhia ana e matou he kowiri i roto i te iti o te aneurysm, he pai te mahi," ko ta Orlando Diaz, MD, he tohunga neuroradiologist wawaotanga i Houston Methodist Hospital, i reira i arahina ai e ia te whakamatautau haumanu FRED, he maha atu nga turoro i era atu hohipera.hōhipera i te USA.USA."Engari ka taea e te porowhita te whakakoi ki roto i te aneurysm nui.Ka taea te whakaara ano me te patu i te manawanui."
Ko te punaha FRED, i hangaia e te kamupene taputapu rongoa MicroVention, ka huri i te rere toto ki te waahi o te aneurysm.Ka kuhuhia e nga taote te taputapu na roto i te microcatheter ka tuu ki te turanga o te aneurysm me te kore e pa tika ki te putea aneurysmal.I te wa e panaia ana te taputapu ki waho o te catheter, ka whakawhänui ki te hanga i te ngongo mata whiri.
Engari i te aukati i te aneurysm, ka mutu tonu a FRED i te rere o te toto i roto i te pute aneurysmal e 35%.
"Ka huri tenei i te hemodynamics, ka maroke te aneurysm," ko ta Diaz te korero.“I muri i te ono marama, ka maroke, ka mate ko ia anake.E iwa tekau paiheneti o nga aneurysm kua ngaro.
Ka roa te wa, ka tipu te kiko huri noa i te taputapu, ka kati i te aneurysm, ka whai hua te hanga i tetahi oko toto hou kua whakatikahia.
