Amadivaysi e-endoluminal aqondisa ukugeleza kabusha, aziwa nangokuthi ama-FRED, ayintuthuko enkulu elandelayo ekwelapheni ama-aneurysms.
I-FRED, ifushane ngedivayisi yokuqondisa kabusha ukugeleza kwe-endoluminal, iyizendlalelo ezimbilii-nickel-ithubhu le-titanium wire mesh elakhelwe ukuqondisa ukugeleza kwegazi nge-aneurysm yobuchopho.
I-aneurysm yobuchopho yenzeka lapho ingxenye ebuthaka yodonga lwe-artery ikhukhumala, yakhe iqhubu eligcwele igazi. Uma ingelashwa, i- aneurysm evuzayo noma ephukile ifana nebhomu lesikhathi elingaholela ekushayweni, ukulimala kobuchopho, ukukoma, nokufa.
Ngokuvamile, odokotela abahlinzayo baphatha i-aneurysms ngenqubo ebizwa ngokuthi i-endovascular coil. Odokotela abahlinzayo bashutheka i-microcatheter ngomthambo omncane we-femoral ku-groin, bayidlulisele ebuchosheni, futhi basonge isaka le-aneurysm, bavimbele igazi ukuthi lingagelezi ku-aneurysm. Indlela isebenza kahle kuma-aneurysms amancane, ama-10 mm noma ngaphansi, kodwa hhayi kuma-aneurysms amakhulu.

"Lapho sifaka ikhoyili ku-aneurysm encane, isebenza kahle," kusho u-Orlando Diaz, MD, isazi se-neuroradiologist esingenele esibhedlela sase-Houston Methodist, lapho ahola khona ukuhlolwa komtholampilo kwe-FRED, okuhlanganisa iziguli eziningi kunanoma yisiphi esinye isibhedlela. esibhedlela e-USA. USA. Kodwa ikhoyili ingajiya ibe yi-aneurysm enkulu, enkulu. Ingaqala kabusha ibulale isiguli.”
Uhlelo lwe-FRED, olwakhiwe inkampani yemishini yezokwelapha i-MicroVention, luqondisa kabusha ukugeleza kwegazi endaweni ye-aneurysm. Odokotela abahlinzayo bafaka idivayisi nge-microcatheter bese beyibeka ngaphansi kwe-aneurysm ngaphandle kokuthinta ngokuqondile isikhwama se-aneurysmal. Njengoba idivayisi iphushwa ngaphandle kwe-catheter, iyanwebeka ukuze yakhe ishubhu elinezikhala eligoqekile.
Esikhundleni sokuvala i-aneurysm, u-FRED wamisa ngokushesha ukugeleza kwegazi esakeni le-aneurysmal ngo-35%.
"Lokhu kushintsha i-hemodynamics, okubangela ukuthi i-aneurysm yome," kusho uDiaz. “Ngemuva kwezinyanga eziyisithupha, igcina ibunile futhi ishona yodwa. Amaphesenti angu-90 ama-aneurysms awasekho."
Ngokuhamba kwesikhathi, izicubu ezizungeze idivayisi ziyakhula futhi zivale i-aneurysm, zenze ngempumelelo umthambo omusha wegazi olungisiwe.
