Izixhobo ezincinci ezihambisa i-endoluminal, ezikwabizwa ngokuba zii-FREDs, yeyona nkqubela phambili ilandelayo kunyango lwee-aneurysms.
I-FRED, imfutshane kwisixhobo sokuhambisa i-endoluminal flow, inamaleko amabininickel-Titanium wire mesh ityhubhu eyenzelwe ukwalathisa ukuhamba kwegazi nge-aneurysm yobuchopho.
I-aneurysm yobuchopho yenzeka xa inxalenye ebuthathaka yodonga lwe-artery idumba, yenze i-bulge egcwele igazi. Xa ishiywe inganyangwanga, i<em>aneurysm evuzayo okanye egqabhukileyo ifana nebhombu yexesha elinokukhokelela kwistroke, ukonakala kwengqondo, isiqaqa nokufa.
Ngokuqhelekileyo, oogqirha baphatha i-aneurysms ngenkqubo ebizwa ngokuba yi-coil endovascular. Oogqirha botyando bafaka i-microcatheter ngokusebenzisa i-microcatheter encinci kwi-artery ye-femoral kwi-groin, bayidlulisele ebuchosheni, kwaye babophe i-sac ye-aneurysm, ukuthintela igazi ukuba liphume kwi-aneurysm. Indlela isebenza kakuhle kwii-aneurysms ezincinci, i-10 mm okanye ngaphantsi, kodwa kungekhona kwii-aneurysms ezinkulu.

"Xa sifaka i-coil kwi-aneurysm encinci, isebenza kakuhle," kusho u-Orlando Diaz, MD, i-neuroradiologist engenelelayo kwisibhedlele sase-Houston Methodist, apho wayekhokela uvavanyo lwezonyango lwe-FRED, olubandakanya izigulane ezininzi kunaso nasiphi na esinye isibhedlele. esibhedlele eMelika. I-USA. Kodwa ikhoyili inokujiya ibe yi-aneurysm enkulu. Isenokuqalisa ngokutsha ize ibulale umguli.”
Inkqubo ye-FRED, ephuhliswe yinkampani yezixhobo zonyango iMicroVention, iphinda iqondise ukuhamba kwegazi kwindawo ye-aneurysm. Oogqirha bafaka isixhobo nge-microcatheter kwaye bayibeke kwisiseko se-aneurysm ngaphandle kokuchukumisa ngokuthe ngqo i-sac aneurysmal. Njengoko esi sixhobo sityhalelwa ngaphandle kwe-catheter, siyakhula sibe ityhubhu ebhijeneyo yomnatha.
Esikhundleni sokuvala i-aneurysm, u-FRED wayeka ngokukhawuleza ukuhamba kwegazi kwi-aneurysmal sac nge-35%.
"Oku kutshintsha i-hemodynamics, ebangela ukuba i-aneurysm yome," kusho uDiaz. “Emva kweenyanga ezintandathu, liyabuna lize lizifele. Amashumi alithoba epesenti ye-aneurysms ayisekho.
Ngokuhamba kwexesha, izicubu ezijikeleze isixhobo ziyakhula kwaye zivale i-aneurysm, ngokufanelekileyo zenze umtya omtsha wegazi olungiswe.
