Aspiration thrombectomy yog cov txheej txheem dav siv los kho mob ischemic stroke, thiab kev xaiv catheter loj yog ib qho tseem ceeb ntawm cov txheej txheem no. Lub aspiration catheter qhov luaj li cas cuam tshuam qhov kev ua tau zoo ntawm thrombectomy thiab kev nyab xeeb ntawm cov txheej txheem. Qhov loj catheter loj tuaj yeem ua rau kom muaj feem cuam tshuam ntawm cov hlab ntsha, tab sis kuj tseem tuaj yeem ua rau muaj kev pheej hmoo ntawm kev raug mob ntawm cov hlab ntsha thiab lub plawv embolization. Hauv qhov sib piv, qhov me me catheter loj tuaj yeem muaj kev nyab xeeb dua tab sis tsis tshua muaj txiaj ntsig hauv kev tshem cov hlab ntsha. Hauv tsab xov xwm no, peb tshuaj xyuas qhov cuam tshuam ntawm aspiration catheter loj ntawm cov txiaj ntsig kho mob hauv aspiration thrombectomy.
Catheter loj - dab tsi yog qhov zoo tshaj plaws?
Qhov zoo tshaj plaws catheter loj rau aspiration thrombectomy yog ib qho kev sib cav, nrog rau ntau lub tuam txhab muab ntau qhov sib txawv catheter. Cov kev tshawb fawb tam sim no qhia tias lub catheter qhov loj me yuav tsum tau txiav txim siab raws li qhov loj ntawm cov hlab ntsha intracranial, lub nra hnyav, thiab cov khoom lag luam. Feem ntau, lub catheter loj dua yog nyiam rau cov hlab ntsha loj dua thiab ntau dua lub nra hnyav, thaum lub catheter me yog siv rau cov hlab ntsha me thiab qis dua lub nra.
Kev cuam tshuam ntawm catheter loj ntawm cov nqi revascularization
The revascularization rates are crucial in aspiration thrombectomy, and catheter size is a significant factor affecting this outcome. Studies have shown that a larger catheter size is associated with higher revascularization rates. For example, a study by Turk et al. found that the revascularization rate was 57.1% for a 5F catheter and 75% for a 6F catheter. Similarly, a study by Nambiar et al. found that a larger catheter size (>5.5F) tau txuam nrog ntau dua thawj-pass reperfusion tus nqi.
Kev cuam tshuam ntawm catheter loj raws sij hawm rau reperfusion
Time to reperfusion is another crucial outcome in aspiration thrombectomy. Studies have shown that a larger catheter size is associated with shorter time to reperfusion. For example, a study by Turk et al. found that the time from groin puncture to reperfusion was shorter with a 7F catheter than with a 5F catheter (37.4 min vs. 50.5 min). Similarly, a study by Turk et al. found that the time to reperfusion was shorter with a larger catheter size (>5.5 F). Cov txiaj ntsig no yog qhov tseem ceeb hauv kev mob stroke ischemic, qhov twg lub sijhawm yog qhov tseem ceeb.
Kev cuam tshuam ntawm catheter loj ntawm kev nyab xeeb
Safety is another critical aspect of aspiration thrombectomy, and larger catheter sizes may increase the risk of complications. Studies have shown that a larger catheter size is associated with more vessel injury, distal embolization, and hemorrhagic transformation. For example, a study by Ciccio et al. found that a 6F catheter was associated with a higher incidence of dissection (16.7%) than a 5F catheter (3.6%). Similarly, a study by Nambiar et al. found that a larger catheter size (>5.5F) tau cuam tshuam nrog qhov tshwm sim ntau dua ntawm distal embolization.

Tag nrho txhua yam, qhov loj me ntawm kev nqus catheter yog qhov tseem ceeb hauv kev ua kom lub cev thrombectomy, cuam tshuam rau kev ua tau zoo thiab kev nyab xeeb. Qhov zoo tshaj plaws catheter loj yuav tsum raug xaiv raws li qhov loj ntawm cov hlab ntsha intracranial, lub nra hnyav, thiab cov khoom pov thawj. Cov kev tshawb fawb tau pom tias qhov loj dua catheter yog txuam nrog ntau dua revascularization tus nqi thiab lub sij hawm luv dua rau reperfusion. Txawm li cas los xij, qhov loj dua catheter kuj tseem tuaj yeem ua rau muaj kev pheej hmoo ntawm cov teeb meem, xws li kev raug mob ntawm cov hlab ntsha, distal embolization, thiab hemorrhagic transformation. Yog li ntawd, kev xaiv ntawm catheter loj yuav tsum tau ua tib zoo xav, coj mus rau hauv tus account tus neeg mob thiab cov txheej txheem txheej txheem.
