ʻO nā hāmeʻa endoluminal hoʻoheheʻe liʻiliʻi liʻiliʻi, ʻike ʻia hoʻi ʻo FREDs, ʻo ia ka holomua nui e hiki mai ana i ka mālama ʻana i nā aneurysms.
ʻO FRED, pōkole no ka endoluminal flow redirecting device, he ʻelua-papanikela-titanium wire mesh tube i hoʻolālā ʻia e kuhikuhi i ke kahe koko ma o ka aneurysm lolo.
Hana ʻia ka aneurysm lolo i ka wā e pehu ai kahi ʻāpana nāwaliwali o ka paia o ke aʻa, e hana ana i kahi puʻupuʻu i piha i ke koko. Ke waiho ʻole ʻia, ʻo ka aneurysm leaking a i ʻole ruptured e like me kahi pōkā manawa hiki ke alakaʻi i ka hahau ʻana, ka lolo, coma, a me ka make.
ʻO ka maʻamau, mālama nā kauka lapaʻau i nā aneurysms me kahi kaʻina i kapa ʻia he endovascular coil. Hoʻokomo ka poʻe ʻokiʻoki i kahi microcatheter ma o kahi ʻoki liʻiliʻi i loko o ke aʻa femoral ma ka ʻāʻī, hele i ka lolo, a wili i ka ʻeke o ka aneurysm, e pale i ke kahe ʻana o ke koko i loko o ka aneurysm. Hana maikaʻi ke ʻano no nā aneurysms liʻiliʻi, 10 mm a i ʻole ka liʻiliʻi, akā ʻaʻole no nā aneurysms nui.

"Ke hoʻokomo mākou i kahi coil i kahi aneurysm liʻiliʻi, hana nui ia," i ʻōlelo ai ʻo Orlando Diaz, MD, he neuroradiologist interventional ma Houston Methodist Hospital, kahi i alakaʻi ai ʻo ia i ka hoʻokolohua lapaʻau FRED, kahi i loaʻa ai nā maʻi ma mua o nā haukapila ʻē aʻe. halemai ma USA. USA. "Akā hiki i ka coil ke hoʻopili i kahi aneurysm nui. Hiki iā ia ke hoʻomaka hou a pepehi i ka mea maʻi. "
ʻO ka ʻōnaehana FRED, i hoʻomohala ʻia e ka hui lāʻau lapaʻau MicroVention, hoʻihoʻi hou i ke kahe koko ma ke kahua o kahi aneurysm. Hoʻokomo ka poʻe ʻoka i ka mea ma o ka microcatheter a kau iā ia ma ke kumu o ka aneurysm me ka hoʻopā ʻole ʻana i ka ʻeke aneurysmal. Ke hoʻokuʻu ʻia ka hāmeʻa i waho o ka catheter, hoʻonui ia e hana i kahi paipu mesh coiled.
Ma kahi o ka hoʻopaʻa ʻana i ka aneurysm, ua hoʻōki koke ʻo FRED i ke kahe koko i loko o ka ʻeke aneurysmal e 35%.
"Hoʻololi kēia i ka hemodynamics, kahi e maloʻo ai ka aneurysm," wahi a Diaz. “Ma hope o ʻeono mahina, maloʻo a make ma kāna iho. He kanaiwa pakeneka o ka aneurysms ua hala.
I ka wā lōʻihi, ulu ka ʻiʻo a puni ka hāmeʻa a hoʻopaʻa i ka aneurysm, e hana maikaʻi ana i kahi moku koko hou i hoʻoponopono ʻia.
