Tab sis tsis txhob txhawj, koj lub plawv tseem tuaj yeem ua haujlwm li qub yam tsis muaj qhov me me no.
Yog li cas tiag tiag tshwm sim nrog LAA?
Nws lub luag haujlwm tseem ceeb yog pab tswj cov ntshav hauv lub plawv. Xav txog, thaum cov ntshav nkag mus rau hauv lub plawv ntau ntxiv thiab cov phab ntsa ntawm LAA ncab, nws tso tawm cov protein hu ua natriuretic peptides rau hauv cov ntshav.
Cov peptides no ua qee yam zoo kawg nkaus hauv peb lub cev:
- Lawv teeb liab peb lub raum kom tso zis ntau ntxiv ntsev thiab dej los ntawm cov zis.
- Nws kuj ua rau peb cov hlab ntsha xoob me ntsis.
Cov txheej txheem no pab txo peb cov ntshav siab.
Tam sim no tej zaum koj yuav xav paub tias muaj dab tsi tshwm sim rau cov peptides no thaum LAA raug phais tshem tawm. Qhov zoo kawg nkaus yog tias li peb lub hlis tom qab phais, lub cev hloov kho thiab cov peptide theem rov qab mus rau qhov qub.
Lub LAA zoo li cas thiab nws cov duab zoo li cas?
Feem ntau nws ntev li ob nti, loj li daim npav rho nyiaj. Nws muaj peev xwm ntim tau li ob diav me me ntawm cov ntshav (kwv yees li 9 milliliters).
Tiamsis tsis yog txhua tus neeg lub LAA zoo ib yam. Muaj ntau yam duab sib txawv. Nyob ntawm cov duab no, qhov kev pheej hmoo ntawm kev mob stroke tuaj yeem sib txawv. Cia peb saib seb cov duab tseem ceeb yog dab tsi.
| Lub npe duab | Kev piav qhia thiab kev pheej hmoo |
|---|---|
| Tis qaib (zoo li tis qaib) | Qhov no yog hom uas feem ntau pom. Nws muaj qhov khoov me ntsis hauv nruab nrab. Qhov no suav tias yog hom uas muaj feem yuav mob stroke tsawg tshaj plaws. |
| Cactus (zoo li cactus) | Muaj ib feem tseem ceeb nyob hauv nruab nrab, thiab lwm qhov uas zoo li ceg tawm ntawm nws. |
| Windsock (zoo li lub hnab cua) | Qhov no tsuas muaj ib feem ntev, tseem ceeb xwb. |

Cov xwm txheej twg cuam tshuam rau LAA?
Muaj ntau yam teeb meem tseem ceeb uas cuam tshuam rau LAA:
- Kev Sib Tsoo: Tej yam xws li kev sib tsoo tsheb tuaj yeem ua rau puas tsuaj lossis rhuav tshem LAA.
- Kev txhaws ntawm lub plawv mitral: Kev nqaim ntawm lub plawv mitral ua rau cov ntshav ntws qeeb los ntawm LAA. Qhov no tuaj yeem ua rau muaj kev pheej hmoo ntawm cov ntshav txhaws.
- Atrial fibrillation (Afib): Qhov no yog qhov peb yuav tsum tau them sai sai rau. Nrog Afib, lub plawv atria tsis ua haujlwm zoo, tab sis hloov chaw co. Qhov no tuaj yeem ua rau cov ntshav sib sau ua ke hauv LAA thiab ua rau muaj kev pheej hmoo ntawm cov ntshav txhaws.
Qhov ua rau mob stroke hauv ib tus neeg uas muaj atrial fibrillation (Afib) yog cov ntshav txhaws uas tsim nyob rau hauv LAA. Mob stroke tshwm sim thaum cov ntshav txhaws no tawg thiab mus rau hauv cov hlab ntsha hauv lub hlwb.
Yuav ua li cas los xyuas seb tus LAA puas noj qab haus huv?
Yog koj tus kws kho mob xav kuaj xyuas qhov mob ntawm LAA, muaj ntau qhov kev kuaj tshwj xeeb rau qhov ntawd.
- Kev siv lub tshuab hluav taws xob transesophageal (TEE): Qhov no yog ib txoj kev kho mob uas siv ib lub raj me me ntxig rau hauv caj pas kom thaij tau cov duab ntawm lub plawv kom meej heev. Qhov no yog ib txoj kev siv ntau heev los saib LAA.
- Kev kuaj MRI (Magnetic Resonance Imaging) thiab Cardiac CT (Computed Tomography) ntawm lub plawv:Cov no tuaj yeem muab cov duab 3D ntxaws ntxaws ntawm lub plawv thiab LAA.
Cov kev kho mob rau LAA yog dab tsi?
Kev kho mob rau LAA nyob ntawm tus neeg mob tus mob.
- Yog tias muaj kev raug mob, nws yuav raug kho los ntawm kev phais .
- Yog tias muaj teeb meem ntawm lub valve, xws li 'mitral valve stenosis', ces yuav kho tau .
- Yog tias muaj kev pheej hmoo ntawm kev mob hlwb vim yog Afib, LAA raug kaw, tshem tawm, lossis thaiv kom tsis txhob muaj cov ntshav txhaws. Qhov no tam sim no yog kev kho mob zoo heev. Qhov no tuaj yeem txo qhov kev pheej hmoo ntawm kev mob hlwb.
Kuv yuav ua li cas thiaj saib xyuas kuv lub siab tau zoo?

Cov Lus Qhia Txog Kev Coj Mus Tsev
- Lub plawv sab laug (Left Atrial Appendage - LAA) yog ib feem me me zoo li lub hnab ntawm lub plawv uas txuas rau lub plawv sab laug. Nws tsis tseem ceeb rau kev ua haujlwm ntawm lub plawv.
- Qhov kev pheej hmoo tseem ceeb ntawm qhov no yog tias rau cov neeg uas muaj Atrial Fibrillation (Afib), cov ntshav txhaws tuaj yeem tsim sab hauv lub plawv, mus rau lub hlwb, thiab ua rau mob stroke.
- Qhov kev pheej hmoo ntawm kev mob stroke sib txawv nyob ntawm seb lub LAA zoo li cas. Lub duab 'cauliflower' yog qhov muaj kev pheej hmoo siab tshaj plaws.
- Kev kaw, tshem tawm, lossis thaiv LAA yog ib txoj kev kho mob zoo los txo qhov kev pheej hmoo ntawm kev mob stroke.
- Yog koj muaj Afib, tham nrog koj tus kws kho mob txog qhov no thiab cov kev kho mob uas yog rau koj.
