Stroke yog ib yam kab mob loj heev uas tuaj yeem ua rau muaj kev tsis taus thiab tuag. Mechanical thrombectomy tau tshwm sim raws li qhov kev kho mob nyiam rau mob ischemic stroke tshwm sim los ntawm cov hlab ntsha loj occlusion. Lub hom phiaj tseem ceeb ntawm kev kho mob thrombectomy yog tshem tawm cov thrombus los kho cov ntshav ntws mus rau lub hlwb thiab txo qhov kev raug mob ntawm lub hlwb. Aspiration catheters feem ntau yog siv los ua ib feem ntawm cov txheej txheem kho mob thrombectomy kom tshem tawm cov thrombus los ntawm cov hlab ntsha. Ib qho ntawm cov ntsiab lus tseem ceeb uas txiav txim siab qhov kev vam meej ntawm kev kho mob thrombectomy yog qhov zoo tshaj plaws ntawm lub aspiration catheter nyob rau hauv kev sib raug zoo rau txoj kab uas hla. Nyob rau hauv tsab xov xwm no, peb yuav tshuaj xyuas cov pov thawj muaj nyob rau ntawm qhov zoo tshaj plaws ntawm lub aspiration catheter nyob rau hauv relation mus rau lub arterial txoj kab uas hla thaum lub sij hawm kho tshuab thrombectomy rau mob stroke.
Cov txheej txheem thrombectomy txhua yam cuam tshuam nrog kev nkag ntawm lub catheter los ntawm cov hlab ntsha femoral hauv puab tais thiab kev nce qib ntawm catheter mus rau qhov chaw ntawm occlusion hauv lub hlwb. Tom qab ntawd lub catheter yog siv los tshem tawm cov thrombus los ntawm cov hlab ntsha occluded. Aspiration catheters feem ntau yog siv rau lub hom phiaj no. Cov catheters no tau muab tso rau hauv lub ntsiab catheter thiab tau nce mus txog thaum nws mus txog qhov chaw ntawm lub thrombus. Lub aspiration catheter ces tsim cov nyhuv suction uas tshem tawm cov thrombus los ntawm cov hlab ntsha.
Ntau yam kev tshawb fawb tau tshawb xyuas qhov pom qhov loj me ntawm lub aspiration catheter nyob rau hauv kev sib raug zoo rau txoj kab uas hla ntawm cov hlab ntsha thaum lub sij hawm kho thrombectomy. Cov kev tshawb fawb no tau pom tias cov catheter loj dua tuaj yeem tshem tawm cov thrombus loj dua, tab sis nws kuj ua rau muaj kev pheej hmoo siab dua ntawm cov hlab ntsha tawg thiab perforation. Ntawm qhov tod tes, ib lub catheter me me yuav tsis tshua muaj txiaj ntsig hauv kev tshem tawm cov thrombus, tab sis nws ua rau muaj kev pheej hmoo tsawg ntawm cov hlab ntsha raug mob.
Mechanical thrombectomy for acute ischemic stroke is effective and includes different technical approaches. Operators use direct aspiration, a stent retriever, or a combination of both. Direct aspiration can be performed with various catheters of different sizes depending on the diameter of the occluded vessel. A study also showed that an association between higher recanalization and a diameter of ratio >0.71 nruab nrab ntawm lub aspiration catheter thiab cov hlab ntsha occluded. Cov txiaj ntsig no tuaj yeem coj kev txiav txim siab txog kev txiav txim siab txog qhov tsim nyog xaiv ntawm aspiration catheters thaum lub tshuab thrombectomy nce tus nqi ntawm kev rov ua tiav. Ib txoj kev tshawb fawb loj tuaj yeem muab cov ntaub ntawv ntxiv los qhia ntxiv txog qhov zoo tshaj plaws piv.Txawm hais tias qhov kev tshawb pom no, qhov zoo tshaj qhov loj ntawm lub aspiration catheter nrog rau txoj kab uas hla ntawm cov hlab ntsha thaum lub sij hawm kho mob thrombectomy rau mob stroke yuav tsum tau txiav txim siab nyob rau hauv cov ntaub ntawv los ntawm lub hauv paus raws li lub cev ntawm lub hom phiaj ntawm lub nkoj, qhov loj ntawm lub thrombus, thiab lub cev. tus neeg ua haujlwm kev paub.
Hauv cov ntsiab lus, qhov pom qhov loj me ntawm lub aspiration catheter cuam tshuam nrog txoj kab uas hla ntawm cov hlab ntsha thaum lub sij hawm kho mob thrombectomy rau mob stroke yog qhov tseem ceeb uas txiav txim siab qhov ua tiav thiab kev nyab xeeb ntawm cov txheej txheem. Cov catheters loj dua tuaj yeem ua tau zoo dua hauv kev rho tawm cov thrombus, tab sis lawv kuj muaj kev pheej hmoo siab dua ntawm cov txheej txheem teeb meem. Ntawm qhov tod tes, me me catheters muaj kev pheej hmoo tsawg dua ntawm cov teeb meem tab sis tej zaum yuav tsis muaj txiaj ntsig zoo hauv kev tshem cov thrombus. Qhov loj ntawm lub catheter yuav tsum tau txiav txim siab raws li lub cev ntawm lub hom phiaj ntawm lub nkoj, qhov loj ntawm lub thrombus, thiab tus neeg teb xov tooj kev paub. Kev tshawb fawb ntxiv yog xav tau los tsim cov lus qhia txog qhov zoo tshaj plaws ntawm kev ua pa catheters hauv tshuab thrombectomy rau mob stroke.
