LavaTMEVOH kua embolic yog ib yam tshiab ntawm cov kua embolic khoom uas tau tsim los kho endovascular ntawm vascular malformations xws li arteriovenous malformations (AVMs) thiab hlwb aneurysms. Cov khoom no muaj cov khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig zoo hauv cov hlab ntsha thaum tseem muaj kev nyab xeeb rau kev siv hauv tib neeg lub cev.
Ib qho tseem ceeb tshaj plaws ntawm LavaTMkua embolic tus neeg saib xyuas yog nws lub peev xwm mus rau diffuse thiab nkag mus rau hauv cov hlab ntsha me tshaj plaws. Cov cuab yeej no yog hu ua "diffusivity" lossis "diffusion coefficient", thiab nws txiav txim siab tias cov khoom siv embolic tuaj yeem kis tau zoo npaum li cas thiab ua rau cov hlab ntsha hauv lub hom phiaj. LavaTMCov kua embolization tus neeg sawv cev muaj qhov sib txawv siab heev, uas txhais tau hais tias nws tuaj yeem yooj yim thiab nrawm nrawm thoob plaws hauv lub vascular network, sau tag nrho cov nooks thiab crannies ntawm cov hlab ntsha txawv txav uas yuav tsum tau occluded.
Lwm qhov tseem ceeb ntawm EVOH embolic tus neeg sawv cev yog nws lub peev xwm los qhia meej meej raws li kev kuaj pom zoo xws li X-ray, CT scan lossis MRI. Cov cuab yeej no yog hu ua "radiopacity" lossis "radiographic visibility", thiab nws yog ib qho tseem ceeb heev rau kev taw qhia cov txheej txheem embolization thiab xyuas kom meej tias cov khoom siv embolization raug faib raws li qhov yuav tsum tau ua. EVOH kua embolic system muaj cov xov tooj cua siab, uas ua rau tus kws phais mob tuaj yeem taug qab nws txoj kev txav mus rau hauv cov hlab ntsha thiab xyuas seb qhov degree ntawm occlusion ntawm cov hlab ntsha.
Ntxiv rau nws qhov diffusivity thiab radiopacity, Lava kuj muaj lwm yam khoom uas ua rau nws muaj txiaj ntsig zoo rau kev kho mob endovascular. Piv txwv li, nws yog biocompatible, txhais tau hais tias nws tsis ua rau muaj kev phiv los yog toxicity rau lub cev nqaij daim tawv, hlwb los yog lub cev. Nws kuj tsis yog nplaum, txhais tau hais tias nws tsis lo rau hauv lub catheter los yog cov phab ntsa ntawm cov hlab ntsha, uas txo qhov kev pheej hmoo ntawm catheter entrapment los yog hlab ntsha puas.
Cov kua nplaum uas tsis yog kua nplaum yog xa mus rau cov hlab ntsha ntawm cov hlab ntsha ntawm lub catheter uas tau muab tso rau hauv ib qho me me ntawm daim tawv nqaij thiab navigated los ntawm cov hlab ntsha uas siv fluoroscopy lossis lwm yam kev yees duab. Ib zaug hauv cov hlab ntsha uas xav tau, cov khoom siv ua kua embolic maj mam txhaj kom txog thaum lub nkoj occluded lossis qhov xav tau qib ntawm embolization tiav. Tus kws phais mob tuaj yeem saib xyuas cov txheej txheem hauv lub sijhawm tiag tiag uas siv cov qauv ntsuas thiab kho tus nqi thiab tus nqi txhaj tshuaj raws li qhov tsim nyog.
