1. Cov txheej txheem stent thrombectomy
Thaum siv lub stent los khaws cov thrombus, tus neeg teb xov tooj yuav tsum tau tsom mus rau yuav ua li cas kom muaj kev sib koom ua ke ntawm lub stent thiab thrombus, thiab tib lub sij hawm ua tib zoo saib xyuas kom txo nws cov kev puas tsuaj rau phab ntsa ntawm cov hlab ntsha.
2. Cov txheej txheem aspiration thrombectomy
Tus yuam sij rau catheter aspiration thrombectomy thev naus laus zis yog yuav ua li cas txhawm rau ua kom lub zog aspiration ntawm lub aspiration catheter ntawm thrombus. Cov nyhuv aspiration nyob ntawm qhov txheeb ze ntawm lub catheter thiab thrombus thiab lub zog aspiration ntawm lub catheter. Thaum siv thev naus laus zis aspiration kom tshem tawm cov thrombus, nws yog ib qho tsim nyog yuav tsum ntsuas txoj kab uas hla ntawm cov hlab ntsha occluded ua ntej ua haujlwm, thiab xaiv lub catheter uas tsim nyog raws li txoj kab uas hla ntawm cov hlab ntsha.
Raws li seb qhov nruab nrab catheter kov lossis hla lub thrombus thiab qhov sib txawv ntawm kev ua haujlwm tsis zoo ntawm lub siab aspiration, thev naus laus zis ntawm stent ua ke aspiration thrombus tshem tawm tuaj yeem muab faib ua ntau txoj hauv kev. Cov txheej txheem Solumbra thaum ntxov (intermediate catheter assisted thrombectomy thev naus laus zis) tau siv los ua ib qho kev ntsuas kho rau aspiration thrombectomy. Thaum lub sijhawm ua haujlwm, lub catheter nruab nrab tuaj yeem hla qhov qhib ntawm anterior cerebral artery (ACA) thiab nkag mus rau hauv nruab nrab cerebral artery yam tsis tau kov lub thrombus. Tab sis qhov nruab nrab catheter thiab stent retriever feem ntau yuav tsis thim tib lub sijhawm. Aspiration pull-back thrombectomy technique (ARTS), thaum tshem cov thrombectomy stent mus rau lub aspiration catheter, nres qhov kev tshem tawm ntawm stent thaum muaj kev tiv thaiv thaum lub sij hawm tshem tawm, thiab khaws cov stent thiab lub aspiration catheter thim tag nrho. Cov yam ntxwv ntawm cov txheej txheem no yog tias lub aspiration catheter thiab stent retrieval raug tshem tawm tib lub sijhawm. Proximal balloon occlusion ua ke nrog cov txheej txheem thrombus aspiration (ASAP) yog kom cov catheter nruab nrab nyob rau hauv qhov chaw raws li thrombus retrieval channel, thiab rub lub thrombus stent retrieval ncaj qha mus rau hauv nruab nrab catheter, uas tuaj yeem tiv thaiv thrombus los ntawm kev khiav mus rau lwm cov hlab ntsha, xws li ACA. SAVE thev naus laus zis yog lub tshuab stent-pab tsis zoo rau lub tshuab kaw lus, uas yog tus cwj pwm nyob rau hauv lub aspiration catheter yog siv los ua kom nquag plias mus rau thrombus, thiab tom qab lub siab tsis zoo yog generated los ntawm lub aspiration catheter. SAVE thev naus laus zis muaj kev ua tau zoo nyob rau hauv ob qho tib si sab hauv kev ncig thiab tom qab ncig cov hlab ntsha loj occlusion thrombectomy. DAT thev naus laus zis (Double Aspiration Technology), uas txuas cov kav ntev / coj cov catheter thiab cov catheter nruab nrab nrog 50ml syringes. Thaum lub stent raug tshem tawm, ob lub koob txhaj tshuaj yog aspirated nyob rau tib lub sij hawm kom tswj tau qhov tsis zoo siab lub xeev rau thrombectomy. Piv nrog rau kev siv tshuab ib txwm siv, DAT thev naus laus zis muaj txiaj ntsig zoo rau thrombectomy. ADVANCE thev naus laus zis thawb lub distal txhawb DAC catheter mus rau qhov kawg ntawm qhov kawg thiab hla lub thrombectomy stent. Tib lub sijhawm ADVANCE thev naus laus zis siv 50ml syringe rau aspiration ntawm qhov kawg. Thaum DAC catheter hla qhov kawg ntawm thrombectomy stent retrieval, tshem lub thrombectomy stent thiab koom tes nrog tsis zoo siab aspiration tib lub sijhawm. Tom qab tshem tawm cov stent, txuas ntxiv nqus tawm yam tsawg 20ml ntawm cov ntshav kom txog thaum tsis muaj thrombus. Yog tias qhov aspiration raug thaiv, tshem DAC catheter nyob rau hauv qhov tsis zoo. Rov qab ib nrab rov qab thev naus laus zis, uas ib nrab tshem tawm thrombectomy stent mus rau hauv lub distal aspiration catheter (rau pem hauv ntej thawb lub aspiration catheter) ua ntej thrombectomy, uas muaj qhov zoo ntawm kev txo cov thrombus fragments thiab vascular puas.
