Transient Ischemic Attack yog hais txog kev cuam tshuam ntawm cov hlab ntsha hauv lub hlwb rau lub sijhawm luv luv, ua rau tsis siv cov ceg tawv lossis lub ntsej muag tuag tes tuag taw. Nws feem ntau ua ntej mob stroke, mob stroke ntawm qhov xwm txheej hnyav dua.

Transient Ischemic Attack, lossis TIA, yog ib qho teeb meem kev noj qab haus huv nyob rau hauv cov ntshav ntawm lub hlwb. Cov tom kawg muaj qhov xav tau tas li yuav tsum tau muab cov pa oxygen, uas cov ntshav coj mus rau nws hauv lub voj voog tsis kawg. Thaum cov ntshav poob qis los yog raug txiav tawm, nws tuaj yeem hu ua ischemia.

Ischemia tuaj yeem tshwm sim hauv txhua lub cev, vim muaj ntau yam ua rau (pob txha txhaws hlab ntsha, los ntshav lossis poob siab). A TIA yog li ntawd ib ntus poob rau hauv cov ntshav mus rau thaj tsam ntawm lub hlwb. Qhov ceev ceev yog qhov tseem ceeb ntawm no, vim tias TIA tsis ua rau muaj qhov tshwm sim, thiab feem ntau tsis kav ntev tshaj li ib teev. Yog tias qhov kev huam yuaj ntev dua, qhov chaw tsis zoo lossis tsis muaj dej hauv cov ntshav hauv lub hlwb yuav sai sai, uas yuav ua rau muaj qhov tshwm sim loj dua: Cerebral Vascular Accident (stroke), lossis infarction.

Peb tuaj yeem xaus lus los ntawm kev hais tias mob stroke yog TIA uas tau ua ntev dhau lawm. Los yog hloov pauv, TIA yog qhov luv luv. Feem ntau ntawm lawv tsis kav ntev tshaj kaum feeb, qhov phem tshaj ob peb teev. Qhov sib txawv yog nyob rau lub sijhawm ntawm qhov tsis muaj oxygen hauv thaj chaw cuam tshuam. Hauv cov ntsiab lus, AIT zoo ib yam li submerging lub taub hau hauv dej rau ob peb feeb, thaum mob stroke yuav poob rau ob peb feeb: qhov tshwm sim ntawm lub hlwb thiab cov kab mob yog dhau qhov ntsuas, tab sis qhov ua rau tseem zoo li qub.

Qhov txawv ntawm cov tsos mob?

Txawm li cas los xij, cov tsos mob yuav zoo ib yam li cov mob stroke, yog li qhov tseem ceeb ntawm kev paub txog lawv. Nws yog li kwv yees tias TIA feem ntau ua ntej mob stroke. Feem ntau cov neeg mob TIA muaj kev pheej hmoo siab mob stroke hauv 90 hnub. 

TIA yog li ntawd ib qho kev tiv thaiv kab mob stroke, nyob rau hauv lub siab hais tias ib tug yooj yim TIA feem ntau yuav tsis muaj txim rau lub faculties ntawm tus neeg mob, tab sis yuav tiv thaiv qhov tshwm sim ntawm mob stroke.

Qhov ua rau TIA yog ischemia, uas yog ib ntus thaiv ntawm cov hlab ntsha hauv lub hlwb. Cov laj thawj ntawm ischemia muaj ntau yam:

Ib qho hlab ntsha thaiv cov hlab ntsha

Lub clot yog ib lo lus siv los piav txog lub thrombus, ib pawg ntawm cov ntshav coagulated. Cov no tuaj yeem tsim ib txwm nyob hauv cov ntshav, thiab txawm tias muaj lub luag haujlwm ntawm kev kho cov kab nrib pleb hauv cov leeg thiab cov hlab ntsha. Tab sis qee zaum, cov "pob txha" no yuav xaus rau hauv qhov tsis ncaj ncees lawm: ntawm kev hla lossis ntawm qhov nkag ntawm lub valve, kom txog thaum lawv thaiv cov ntshav.

Nyob rau hauv rooj plaub ntawm TIA, lawv thaiv cov ntshav uas coj mus rau hauv cov hlab ntsha hauv ib cheeb tsam ntawm lub hlwb. Yog tias lawv tau tso tseg rau lub sijhawm ntev, nws tuaj yeem ua rau mob stroke, thiab ua rau qhov chaw qhuav. Hauv TIA, cov hlab ntsha zoo li tuaj tawm ntawm nws tus kheej, lossis tawg lawm.

Rupture, los ntshav

Hauv qhov no, cov hlab ntsha raug txiav lossis puas, hauv zos lossis sab hauv, uas tuaj yeem ua rau lub hlwb hemorrhage, uas los ntawm coagulating tuaj yeem ua rau ischemia.

Tshuab, compression

Compressed hlab ntsha nyob rau hauv lub hlwb tuaj yeem ua rau TIA yog tias cov hlab ntsha tau raug thaiv ib ntus.

Cov tsos mob ntawm TIA yog tib yam li cov mob stroke, tab sis rau lub sijhawm luv dua (los ntawm ob peb feeb mus rau ob peb teev feem ntau). Nov yog cov tsos mob tshwm sim tshaj plaws: 

• Sudden tsis pom kev nyob rau hauv ib lub qhov muag;
• Lub ntsej muag tuag tes tuag taw ntawm ib sab;
• Nyuaj qhia txog tus kheej hauv lub sijhawm luv luv;
• Poob lub zog nyob rau hauv ib tug limb (caj npab, ceg), nyob rau tib sab.

Mus ntsib koj tus kws kho mob sai sai

Qhov yuam kev tsis ua tom qab AIT yog coj nws maj mam. TIA feem ntau yog qhov ua ntej ntawm mob stroke. Yog li, txawm tias koj zoo dua tom qab ob peb feeb, thiab cov tsos mob tau ploj mus, koj tseem yuav tau ceev nrooj hu rau tus kws kho mob kom kuaj xyuas koj lub hlwb. Piv txwv li, nws muaj peev xwm ua rau cov ntshav txhaws hauv cov hlab ntsha hauv lub hlwb tseem nyob, thiab cov ntaub ntawv tshiab, lub sijhawm no loj dua.

Hu rau SAMU

Yog tias tsis ntseeg, nws tuaj yeem tiv tauj SAMU sai li sai tau thaum cov tsos mob tshwm sim ntau feeb. Thaum cov no tau ploj lawm, nws yog qhov zoo dua los tham nrog koj tus kws kho mob sai sai yam tsis tau ncua sijhawm.

Kev pw hauv tsev kho mob

Yog tias tus kws kho mob pom tias nws tsim nyog, kev mus pw hauv tsev kho mob yuav raug pom zoo thaum qee qhov kev sim ua tiav:

• MRI (Magnetic Repulsion Imaging);
• Ultrasound ntawm cov hlab ntsha ntawm lub caj dab lossis lub plawv;
• Kuaj ntshav.

Qhov ua rau TIA muaj ntau haiv neeg, thiab feem ntau txuas rau tus neeg mob txoj kev ua neej lossis ntau yam pathologies:

• Muaj cov roj (cholesterol) siab hauv cov ntshav;
• Mob ntshav qab zib;
• Ntshav siab;
• Kev rog, kev ua neej nyob sedentary;
• Haus luam yeeb, cawv;
• Arrhythmia, lub plawv dhia tsis zoo.

Txhua qhov laj thawj no yuav muaj kev tiv thaiv sib txawv, los ntawm kev noj zaub mov mus rau kev tawm dag zog lub cev, uas yuav tsum tau tsom mus rau koj tus kws kho mob.
