Spontaneous subarachnoid hemorrhage yog ib yam kab mob uas muaj kev tuag siab thiab muaj kev tsis taus. Qhov tshwm sim feem ntau yog aneurysm rupture thiab los ntshav. Aneurysms yog qhov zoo tshaj plaws kho nrog kev cuam tshuam embolization. Ntawm cov aneurysms uas tau kho nrog kev cuam tshuam embolization, qee qhov aneurysms muaj lub caj dab dav, thiab nws nyuaj rau ua tiav embolization siv ib qho microcatheter embolization. Stents, balloons lossis lwm yam kev pabcuam embolization yuav tsum tau ua. Muab ob npaug rau microcatheter thev naus laus zis yog ib txoj hauv kev xaiv nrog rau qhov tshwj xeeb ntawm kev siv.
Yooj yim coil packing yog qhov nyuaj dua rau qhov dav-caj dab aneurysms. Tsuas yog nrog kev pab los ntawm balloons lossis stents tuaj yeem khaws cia ntawm lub caj dab dav aneurysms thaum ua rau niam txiv cov hlab ntsha patency. Txawm li cas los xij, nws qhov tsis zoo tseem ceeb yog:
1. Muaj ib qho kev xa khoom ntxiv thiab lub stent microcatheter yog qhov nyuaj, uas yog qhov nyuaj rau qhov chaw rau tortuous lossis distal aneurysms.
2. Cov tshuaj antiplatelet aggregation yuav tsum tau tom qab phais.
3. Cov txheej txheem ntim cov zais pa yuav tsum muaj kev thaiv ib ntus ntawm cov niam txiv cov hlab ntsha ntawm cov hlab ntsha, ua rau muaj kev pheej hmoo ntawm ischemia.
4. Lub stent lossis balloon txwv kev txav ntawm lub microcatheter thiab cuam tshuam rau kev ntim khoom.
5. Kev tso tawm ntawm stent ntawm bifurcation ntawm cov hlab ntsha tuaj yeem txo cov ntshav ntws mus rau sab nraud thaum tiv thaiv cov ntshav ntws ntawm ib sab, yog li ua rau muaj kev pheej hmoo ntawm ischemia.
Ob chav microcatheter thev naus laus zis rau embolizing aneurysms yog qhov tsim nyog rau aneurysms nrog lub caj dab dav, uas yog, aneurysms nrog lub caj dab / qog lub cev ntau dua lossis sib npaug rau 0.5 tab sis tsawg dua lossis sib npaug rau 1. Ob chav microcatheter thev naus laus zis expands qhov kev siv ntawm yooj yim coil aneurysm packing. Piv nrog rau qhov tsis xws luag ntawm balloon lossis stent-pab thev naus laus zis, nws qhov zoo yog:
1. Kev ua haujlwm yog qhov yooj yim. Ob lub microcatheters tuaj yeem ua haujlwm tib lub sijhawm los ntawm tib lub 6F qhia catheter. Lub microcatheter hloov tau yooj yim dua li stent catheter thiab yooj yim mus cuag cov hlab ntsha distal.
2. Tsis tas yuav tsum tau thaiv cov hlab ntsha ntawm cov qog nqaij hlav ib ntus thaum phais kom txo tau qhov kev pheej hmoo ntawm ischemia.
3. Tsis tas yuav txhawj xeeb txog qhov yuav tsum tau muaj cov tshuaj tiv thaiv kab mob sib sau ua ke tom qab kev phais vim kev tso stent.
4. Piv nrog ib leeg microCatheter emolatheter, ob npaug cov microcatheter muaj teeb meem ntawm cov kab noj hniav sib txawv, uas muaj cov teeb meem ntawm cov microCatheter thaum phais.
