Cia peb kawm txog Subclavian Artery, yog ib qho ntawm cov hlab ntsha tseem ceeb tshaj plaws uas nqa ntshav mus rau koj lub xub pwg nyom, caj dab, thiab taub hau!

Nyob zoo! Koj puas tau xav paub tias koj txhais caj npab, caj dab, thiab qee qhov ntawm koj lub taub hau tau ntshav li cas? Peb lub cev muaj cov hlab ntsha zoo kawg nkaus. Hnub no peb yuav tham txog ib qho tseem ceeb tshaj plaws, tab sis tej zaum tsis tshua muaj neeg tham txog, ntawm lub cev ntawd. Ntawd yog cov hlab ntsha subclavian .

Cov hlab ntsha subclavian yog dab tsi? Nws ua dab tsi?

Hais yooj yim xwb, koj cov hlab ntsha subclavian yog ob lub hlab ntsha tseem ceeb uas nqa cov ntshav nplua nuj oxygen los ntawm koj lub plawv mus rau koj lub cev sab saud, suav nrog koj txhais tes, caj dab, thiab taub hau. Xav txog lawv zoo li ob lub kav dej tseem ceeb uas nqa dej los ntawm lub taub dej mus rau koj lub tsev. Lawv nyob hauv qab koj cov pob txha caj dab (hu ua koj cov clavicles), ib qho ntawm txhua sab. Muaj ob sab ntawm sab xis thiab ob sab ntawm sab laug.

Yog li, txoj haujlwm tseem ceeb ntawm cov hlab ntsha subclavian no yog xa cov ntshav oxygenated los ntawm lub plawv mus rau koj lub taub hau, caj dab, thiab caj npab. Ib txoj haujlwm tseem ceeb heev, puas yog?

Peb tuaj yeem nkag siab nws txoj haujlwm los ntawm kev faib cov hlab ntsha no ua peb ntu:

• Qhov thib ob mus rau qhov chaw ntawm koj lub caj dab hu ua costocervical trunks .
• Qhov thib peb , uas yog qhov nyob deb me ntsis ntawm qhov chaw uas cov hlab ntsha no pib, muab ntshav rau koj txhais tes. Qhov ntawd txhais tau tias ntshav mus rau txhua yam los ntawm koj cov leeg nqaij biceps, triceps, cov leeg nqaij xub pwg nyom, cov leeg nqaij caj npab, thiab lwm yam.

Cov hlab ntsha subclavian nyob qhov twg tiag?

Raws li peb tau hais ua ntej lawm, ob lub hlab ntsha no nyob hauv qab koj cov pob txha caj dab (cov 'clavicles'). Txawm li cas los xij, cov hlab ntsha sab laug subclavian thiab cov hlab ntsha sab xis subclavian pib txawv me ntsis.

• Cov hlab ntsha sab xis subclavian ntawm koj sab xis pib nrog ib txoj hlab ntsha hu ua koj cov hlab ntsha brachiocephalic .
• Cov hlab ntsha sab laug subclavian ntawm koj sab laug pib ncaj qha los ntawm lub arch ntawm koj cov hlab ntsha loj loj, lub aortic arch .

Ob lub hlab ntsha no mus ncig sab nraud ntawm nruab nrab ntawm koj lub cev, dhau los ntawm ob lub leeg nqaij hauv koj lub caj dab hu ua "cov leeg nqaij scalene pem hauv ntej thiab nruab nrab. " Lawv txuas mus rau koj tus tav thawj zaug, thiab los ntawm qhov ntawd lawv dhau los ua "axillary arteries," uas yog cov hlab ntsha uas mus ncaj qha rau koj txhais caj npab.

Cov hlab ntsha subclavian no txuas mus ua cov ceg me me. Lawv kuj tseem ceeb heev:

• Cov hlab ntsha ntawm lub vertebral: Cov no muab ntshav rau qee qhov ntawm koj lub hlwb thiab lub brainstem . Cov hlab ntsha no feem ntau yog nruab nrab ntawm 3 thiab 5 millimeters hauv txoj kab uas hla.

Yog tias qhov no tshwm sim hauv cov hlab ntsha subclavian, nws thaiv cov ntshav ntws.
• Thoracic Outlet Syndrome: Hauv qhov mob no, cov hlab ntsha subclavian ua rau nqaim ( stenosis) vim muaj kev nyuaj siab los ntawm cov pob txha, cov leeg, lossis lwm cov ntaub so ntswg.) hloov. Ces cov ntshav uas mus rau tes yuav txo qis.
• Takayasu's arteritis: Qhov no yog ib hom vasculitis . Nws ua rau o, lossis o, ntawm cov hlab ntsha subclavian, uas tuaj yeem txo qhov ntau ntawm cov pa oxygen mus txog lub taub hau, caj dab, lossis caj npab.
• Kab mob Subclavian Steal Syndrome: Qhov no feem ntau yog tshwm sim los ntawm atherosclerosis . Qhov tshwm sim ntawm no yog tias cov hlab ntsha subclavian tau nqaim ( stenosis ), thiab qee cov ntshav uas yuav tsum mus rau lub hlwb tau "nyiag" ntawm caj npab. Yog vim li ntawd nws thiaj hu ua "nyiag."

Cov tsos mob ntawm teeb meem ntawm cov hlab ntsha subclavian yog dab tsi? Koj paub li cas?

Yog tias muaj teeb meem nrog cov hlab ntsha subclavian, cov tsos mob yuav txawv nyob ntawm tus kab mob uas cuam tshuam rau nws. Txawm li cas los xij, muaj qee cov tsos mob uas pom tau:
