Lisebelisoa tse nyane tse tsamaisang phallo ea endoluminal, tse tsejoang hape e le FREDs, ke tsoelo-pele e latelang e kholo kalafong ea li-aneurysms.
FRED, e khuts'oane bakeng sa sesebelisoa sa ho tsamaisa phallo ea endoluminal, e na le likarolo tse pelinikele-titanium wire mesh tube e etselitsoeng ho tsamaisa phallo ea mali ka aneurysm ea boko.
Aneurysm ea boko e etsahala ha karolo e fokolang ea lerako la mothapo oa mali e kokomoha, e etsa leqhubu le tletseng mali. Ha e sa phekoloe, aneurysm e lutlang kapa e phatlohileng e tšoana le bomo ea nako e ka lebisang ho oeng, ho senyeha ha boko, ho akheha le lefu.
Ka tloaelo, lingaka tse buoang li phekola aneurysms ka mokhoa o bitsoang coil endovascular. Lingaka tse buoang li kenya microcatheter ka lesoba le lenyenyane la mothapo oa mothapo oa botšehali ka har'a groin, li o fetisetsa bokong, 'me li khoaela mokotla oa aneurysm, ho thibela mali ho phalla ka har'a aneurysm. Mokhoa ona o sebetsa hantle bakeng sa li-aneurysms tse nyane, 10 mm kapa ka tlase, empa eseng bakeng sa li-aneurysms tse kholoanyane.

Lingaka tse buoang li kenya sesebelisoa ka microcatheter ebe li e beha botlaaseng ba aneurysm ntle le ho ama ka ho toba mokotla oa aneurysmal. Ha sesebelisoa se sutumetsoa ka ntle ho catheter, sea atoloha ho etsa tšupu ea letlooeng.
Sebakeng sa ho koala aneurysm, FRED hang-hang e ile ea emisa phallo ea mali ka mokotleng oa aneurysmal ka 35%.
"Sena se fetola hemodynamics, e leng se etsang hore aneurysm e ome," ho boletse Diaz. “Ka mor’a likhoeli tse tšeletseng, e qetella e pona ’me e shoa ka bobona. Liphesente tse mashome a robong tsa li-aneurysms li felile. ”
