Nyob rau hauv cov teb ntawm neurointerventional thiab peripheral vascular interventional kev kuaj mob thiab kev kho mob, vascular embolization tshuab tau dhau los ua ib txoj hauv kev rau kev kho cov kab mob vascular xws li arteriovenous malformations thiab vascularized hlav. Cov kua embolization tshuab, nrog rau lawv qhov zoo ntawm kev nkag mus tau yooj yim thiab tswj tau occlusion, maj mam dhau los ua qhov kev xaiv tseem ceeb hauv kev kho mob. Nrog kev ua tiav tas mus li hauv kev siv tshuab kho mob hauv tsev, cov ntaub ntawv ua kua embolization raws li EVOH copolymers tau dhau los ua kev hloov kho thev naus laus zis, nqa cov tshuaj tshiab rau kev kho mob me me ntawm cov kab mob vascular.
Tus nqi tseem ceeb ntawm cov kua embolization yog nyob rau hauv kev kov yeej cov kev txwv ntawm cov tsoos mechanical embolization cov neeg ua haujlwm, ua rau lawv nkag mus tob rau hauv cov kab mob vascular tsis zoo thiab cov microvessels distal kom ua tiav vascular occlusion. Piv nrog rau cov khoom siv kho tshuab embolization xws li coils, cov kua embolization cov neeg ua haujlwm raug xa mus rau hauv cov kua dej, hloov mus rau qhov nyuaj vascular anatomy, tshwj xeeb tshaj yog tsom rau cov qauv nested ntawm arteriovenous malformations, ua tiav cov nyhuv embolization ntau dua thiab txo qhov kev pheej hmoo ntawm kev rov ua haujlwm tom qab. Tam sim no, cov chaw kho mob tseem ceeb ua kua embolization cov neeg ua haujlwm siv EVOH copolymers ua cov khoom tseem ceeb, ua ke nrog dimethyl sulfoxide (DMSO) hnyav thiab cov neeg ua haujlwm sib txawv. Qhov kev sib xyaw ua ke ntawm biocompatibility thiab kev tswj hwm kev ua haujlwm ua rau nws nyiam cov khoom siv los kho cov kab mob neurovascular thiab peripheral vascular.
Raws li qhov tseem ceeb ntawm kev ua kua embolization thev naus laus zis, daim ntawv thov ntawm EVOH copolymer tsis yog -adhesion thev naus laus zis tau daws tag nrho cov teeb meem ntawm cov tshuaj embolization cov neeg nyiam ua raws li catheters thiab muaj kev pheej hmoo ua haujlwm siab. Cov tiam tom ntej ntawm cov khoom, sawv cev los ntawm LAVA kua embolization system, tso siab rau qhov tseeb EVOH copolymer thev naus laus zis kom ua tiav tsis yog - nplaum xa tawm ntawm tus neeg sawv cev embolization. Qhov no tsis txhob muaj teeb meem kev phais xws li catheter tuav thiab tso cai rau nag lossis daus thiab khov kho kom tsim tau lub vascular cam khwb cia, ua kom lub neej ntev ntawm cov nyhuv embolization. Tsis tas li ntawd, txhawm rau hloov mus rau cov xwm txheej sib txawv, cov kua dej embolization muaj cov qauv tsim viscosity, xws li qis viscosity (12 cSt) mus rau siab viscosity (34 cSt), ua tau raws li qhov sib txawv ntawm cov kev xav tau ntawm distal microvascular embolization, kev kho cov kab mob vascular, thiab siab -. kev khiav hauj lwm ntau hom phiaj.
Precise visualization thiab controllable xa yog lwm qhov tseem ceeb ntawm cov kua embolization tshuab. Qhov sib ntxiv ntawm ultra-micronized tantalum hmoov zoo txhim kho qhov pom ntawm tus neeg sawv cev embolic nyob rau hauv kev yees duab, tso cai rau cov kws kho mob saib xyuas nws cov dej ntws thiab kev faib tawm hauv lub sijhawm tiag tiag rau lub hom phiaj embolization. Txhim kho cov kua dej ua kom tus neeg sawv cev embolic nkag mus tob rau hauv cov hlab ntsha, thiab ua ke nrog txoj kev xa khoom ruaj khov, maj mam ua tiav cov vascular occlusion, txhim kho qhov kev phais zoo. Hauv kev siv tshuaj kho mob, cov tshuab ua kua embolization tau dav siv rau kev kho mob embolization ntawm intracranial arteriovenous malformations, peripheral vascular malformations, thiab cov qog vascularized heev, dhau los ua cov cuab yeej tseem ceeb rau kev kho mob me me.
Nrog rau qhov nrov ntawm kev cuam tshuam kev kuaj mob thiab kev kho cov thev naus laus zis hauv Suav teb thiab kev nrawm ntawm kev hloov pauv hauv tsev, cov kua embolization tshuab tau siv rau hauv txoj hauv kev tshiab. Cov kev xav tau ntawm kev kho mob rau qhov tseeb, tsis tshua muaj kev cuam tshuam, thiab kev kho kom zoo yog tsav kev txhim kho cov ntaub ntawv embolization mus rau biocompatibility siab dua thiab kev ua haujlwm zoo dua. Cov khoom tsim hauv tsev, ua piv txwv los ntawm LAVA kua embolization system, tau ua tiav qhov sib xws nrog cov thev naus laus zis thoob ntiaj teb ua tsaug rau lawv cov txiaj ntsig tseem ceeb xws li kev tiv thaiv viscosity tag nrho, tsis yog - nplaum thev naus laus zis, thiab pom meej meej. Tsis tas li ntawd, lawv cov khoom tsim, haum rau cov kev xav tau ntawm kev kho mob, muab cov kws kho mob hauv tsev nrog tus nqi - kev xaiv kho tau zoo.
Nyob rau hauv lub neej yav tom ntej, kua embolization tshuab yuav mus txuas ntxiv mus rau ntau dua precision,kev txawj ntse, thiab adaptability rau complex lesions. Kev txuas ntxiv mus rau hauv kev siv thev naus laus zis hauv tsev yuav txhawb nqa kev siv dav dav ntawm vascular embolization therapy, coj kev cia siab tshiab rau kev kho mob me me rau ntau tus neeg mob cov kab mob vascular thiab pab Tuam Tshoj txoj kev kho mob kev lag luam nkag mus rau theem tshiab ntawm - kev txhim kho zoo.
