Thrombectomy rau distal vascular occlusion yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus ntawm cov cuab yeej xaiv thiab kev siv. Nws yog ib qho tsim nyog yuav tsum tsom rau kev txiav txim siab kom muaj kev nyab xeeb ntawm cov hlab ntsha distal thrombectomy kom ntau li ntau tau thaum lub sij hawm thrombectomy.
01 Microcatheter Micro Guide Wire Super Xaiv:
Rau stent thrombectomy nyob rau hauv cov hlab ntsha distal, nws yog ib qho tsim nyog los xaiv lub microcatheter mus rau qhov kawg ntawm qhov occlusion ua ntej, tshwj xeeb tshaj yog rau thrombus distal rau M2. Lub microcatheter feem ntau yuav tsum tau xaiv los ntawm M3, tsuas yog nyob rau hauv txoj kev no tuaj yeem ua haujlwm zoo ntawm cov stent nrog rau lub cev tseem ceeb ntawm cov thrombus, thaum tseem ua kom haum rau qhov tsis raug qhov kawg ntawm qhov kawg ntawm stent retriever. Txij li thaum cov hlab ntsha distal feem ntau tsis muaj zog hauv cov qauv thiab tortuous.Tej zaum yuav muaj kev hloov pauv thiab kev puas tsuaj ntawm cov hlab ntsha distal thaum lub sijhawm xaiv super, uas muaj qee yam txaus ntshai. Yog li ntawd, qhov nro ntawm tag nrho microcatheter thiab micro qhia xov hlau yuav tsum raug tso tawm hauv lub sijhawm thaum ua haujlwm. Lub taub ntawm micro qhia xov hlau yuav tsum tau zoo li tus me J zoo li ntau li ntau tau kom tsis txhob tag nrho lub cev dhia mus rau pem hauv ntej thiab ua rau cov hlab ntsha perforation. Rau qhov nyuaj embolisms, tej zaum yuav muaj teeb meem nyob rau hauv lub microcatheter microguide xaim, rov xaiv superselection yuav ua rau puas cov hlab ntsha, thiab txawm ua rau cov hlab ntsha perforation, uas yuav tsum tau kom peb yuav tsum tau maj mam thiab ceev faj nyob rau hauv lub lag luam.
02 Kev xaiv ntawm Thrombectomy Stent Retriever:
Cov qauv sib txawv ntawm thrombectomy stent retrieval li muaj qhov sib txawv ntawm txoj haujlwm ntawm microcatheter. Yog hais tias muaj ib tug distal tuag-kawg tsim, lub microcatheter yuav tsum tau muab tso rau deb. Yog tias tsis muaj qhov tsim nyog tuag, lub microcatheter tsis tas yuav tsum tau muab tso rau hauv qhov chaw deb dhau. Xav txog qhov kev pheej hmoo ntawm kev ua haujlwm tau coj los ntawm qhov kev xaiv ntawm qhov distal microcatheter thiab qhov kawg tuag, nws raug nquahu kom siv lub thrombectomy stent yam tsis muaj qhov kawg tsim rau qhov kawg ntawm lub nkoj occlusion.
03 Siv rau Intermediate Catheter:
Thrombectomy nyob rau hauv cov hlab ntsha distal yuav tsum tau txhawb nqa thiab pab los ntawm ib tug catheter nruab nrab. Vim yog tus txheej txheem ntawm thrombectomy nyob rau hauv lub distal hlab ntsha, cov hlab ntsha loj yuav tshwm sim thaum lub sij hawm ntawm rub rov qab lub thrombus stent retrieval. Piv txwv li, yog hais tias lub M2 ntu yog occluded, lub stent tau daig nyob rau hauv lub thrombus thaum lub sij hawm stent retrieval txheej txheem, kev sib txhuam quab yuam ntawm lub thrombus retrieval stent thiab lub vascular stent kuj loj, uas yuav ua rau cov kev hloov ntawm M2 thiab M1 hlab ntsha. , uas ua rau rupture ntawm vascular perforator thiab M1 hlab ntsha. Nyob rau hauv cov ntaub ntawv ntawm thrombectomy, peb tuaj yeem pom S-puab lossis yoj-puab hloov pauv deformation ntawm proximal M1, uas yog tshwm sim los ntawm kev hloov ntawm cov hlab ntsha thaum lub sij hawm thrombectomy. Nyob rau tib lub sijhawm, nws tseem yuav ua rau lub zog shear ntawm M1 thiab sab hauv carotid artery stent hlab ntsha, ua rau muaj kev puas tsuaj rau cov hlab ntsha tseem ceeb. Yog li ntawd, rau cov ceg ntawm cov hlab ntsha distal, cov catheter nruab nrab tuaj yeem ncav cuag M1 lub cev lossis qhov kawg ntawm M1 raws li qhov kev txhawb nqa kom txo tau cov hlab ntsha ntawm qhov thim rov qab, yog li txo qhov kev pheej hmoo ntawm vascular rupture thaum M2 thrombectomy.
04 Tso Tawm Stent Retriever:
Ntev stent retrievals tsis tas yuav muaj qhov zoo dua hauv kev tshem tawm cov hlab ntsha distal. Qhov laj thawj tseem ceeb yog qhov thrombus ntawm cov hlab ntsha embolism feem ntau luv dua, uas tsis tas yuav muaj lub nra hnyav dua li cov hlab ntsha loj occlusion. Thib ob, ntev thiab loj dua thrombectomy stents yuav muaj kev tiv thaiv tom qab tso tawm, ua rau muaj kev cuam tshuam vascular loj. Yog li ntawd, nws tsis tas yuav tso tag nrho cov stent retriever rau ntev stents. Kev tso tawm ntawm stent retrieval tsuas yog xav tau lub cev tseem ceeb ntawm stent los npog cov ntu occlusion. , thiab qhov sib thooj tsis tas yuav tsum tau tso tawm tag nrho, thiab nws yooj yim dua los txo qhov kev tawm tsam no los ntawm kev xaiv ib qho me me stent.
05 Thrombectomy Stent Recovery:
Cov txheej txheem ntawm stent tshem tawm yuav tsum tau ua tib zoo saib xyuas kom tshem tawm thiab deformation ntawm cov hlab ntsha. Yog tias muaj kev tawm tsam ntau heev thaum lub sijhawm rub rov qab, nws yog qhov yuav tsum tau tshem tawm ib feem ntawm stent, thiab tom qab ntawd sim rub rov qab dua kom txog thaum qhov kev tiv thaiv tuaj yeem tswj tau. Nws tuaj yeem pom tias stent retriever tuaj yeem txav mus qeeb. Qee zaum, nws yuav nyuaj rau khaws cov stent. Lub sijhawm no, kev pab cuam ntawm lub catheter nruab nrab yog xav tau los muab nws, txwv tsis pub qhov kev quab yuam rov qab yuav ua rau muaj kev pheej hmoo ntau dua ntawm kev raug mob vascular. Yog li ntawd, xav txog qhov kev pheej hmoo no, ib feem ntawm kev tso tawm ntawm thrombectomy stent yog ib qho kev xaiv zoo.
Distal vascular thrombectomy yog ib qho txuj ci heev. Txawm hais tias feem ntau ntawm cov stent retrievals yog ib qho yooj yim rau recanalize, tseem muaj ntau cov kev cov nyom nyob rau hauv tej rooj plaub. peb yuav tsum tau xyuam xim rau cov ntsiab lus ntawm txhua qhov kev khiav hauj lwm los ntawm super xaiv micro phau ntawv qhia rau kev txhawb nqa ntawm nruab nrab catheter, thiab peb kuj yuav tsum tau ua tib zoo ua hauj lwm ntau dua, thiaj li yuav txo tau txoj kev pheej hmoo ntawm kev ua hauj lwm thiab pab cov neeg mob kom tau recanalization yam xyuam xim.
