Taw qhia
Intracranial aneurysm yog ib qho kev puas siab puas ntsws uas ua rau muaj kev hem thawj rau tus neeg mob. Cov tsos mob no yog tshwm sim los ntawm bulging los yog ballooning ntawm phab ntsa ntawm cov hlab ntsha nyob rau hauv lub hlwb. Yog tias tsis kho, qhov aneurysm tuaj yeem tawg, ua rau hemorrhagic stroke. Cov kev tshawb fawb tau pom tias ruptured intracranial aneurysms yog lub luag hauj lwm rau kwv yees li 80% ntawm tag nrho cov uas tsis yog-traumatic subarachnoid hemorrhage mob. Ua tsaug, kev nce qib hauv kev kho mob thev naus laus zis tau muab cov kev xaiv tshiab rau kev kho mob intracranial aneurysms, suav nrog kev siv cov kua embolic.
Liquid Embolic Agents
Liquid embolic agents (LEAs) yog ib hom khoom siv kho mob uas tau txhaj rau hauv cov hlab ntsha nrog lub hom phiaj ntawm kev ua kom lub cev tsis muaj zog thiab txhawb kev tsim cov ntshav txhaws. LEAs tuaj nyob rau hauv ob hom: non-adhesive thiab nplaum. Cov tshuaj tsis yog nplaum muaj xws li ethylene vinyl cawv thiab n-butyl cyanoacrylate.
Qhov zoo ntawm Liquid Embolic Agents
1. Ua tiav Aneurysm Occlusion: Ib qho txiaj ntsig tseem ceeb ntawm kev siv LEAs hauv kev kho mob intracranial aneurysms yog lawv lub peev xwm ua tiav occlusion ntawm aneurysm. Aneurysm occlusion yog ua tiav los ntawm kev txhaj tshuaj ntawm LEAs ncaj qha mus rau hauv cov hlab ntsha, qhov chaw uas lawv polymerize thiab tsim cov khoom ntim ruaj khov uas tiv thaiv cov ntshav ntws mus rau hauv lub hnab aneurysm. Thaum lub aneurysm tau occluded, qhov kev pheej hmoo ntawm rupture yog ho txo.
2. Kev Txhim Kho Lub Sij Hawm Ntev: Vim lawv muaj peev xwm ua tiav occlusion tiav, LEAs tau pom tias yuav txhim kho cov txiaj ntsig ntev rau cov neeg mob intracranial aneurysms. Cov kev tshawb fawb tau pom tias qhov rov tshwm sim tom qab kho endovascular aneurysm yog qhov qis dua thaum LEAs tau siv piv rau ntau txoj hauv kev.
3. Txo lub Sijhawm Txheej Txheem: Lwm qhov tseem ceeb ntawm kev siv LEAs hauv kev kho mob intracranial aneurysms yog lub sijhawm txo cov txheej txheem. Piv nrog rau lwm cov kev kho mob endovascular aneurysm, kev siv LEAs tuaj yeem txo lub sijhawm xav tau rau cov txheej txheem. Qhov no yog vim kev siv LEAs tshem tawm qhov xav tau rau ntau qhov kev hla ntawm lub catheter.
4. Yam tsawg kawg nkaus raug hluav taws xob: Raws li nrog rau tag nrho cov txheej txheem endovascular, ib qho tsis zoo yog qhov muaj peev xwm raug hluav taws xob. Txawm li cas los xij, nrog kev siv LEAs, qhov hluav taws xob raug rau tus neeg mob thiab pab pawg kho mob tau txo qis. Cov txheej txheem tuaj yeem ua tau raws li cov tshuaj fluoroscopy tsawg lossis tsis muaj fluoroscopy.
Xaus
Hauv kev xaus, intracranial aneurysms sawv cev rau kev noj qab haus huv tseem ceeb rau cov tib neeg cuam tshuam. Txawm li cas los xij, kev siv cov tshuaj ua kua embolic muab txoj hauv kev nyab xeeb thiab zoo los kho cov no. Kev siv cov tshuaj no tsis yog tsuas yog ua kom tiav occlusion ntawm aneurysm tab sis kuj txhim kho cov txiaj ntsig ntev rau cov neeg mob. Nrog rau kev nce qib ntxiv hauv kev kho mob, nws cia siab tias kev siv cov kua embolic cov neeg ua haujlwm txuas ntxiv yuav yog ib qho kev kho mob zoo rau cov neeg mob uas muaj intracranial aneurysms.
