Cia peb kawm txog lub 'hlab ntsha' tseem ceeb ntawm koj lub plawv (Ascending Aorta) thiab nws qhov tseem ceeb.

Niaj hnub no peb yuav tham txog ib feem tseem ceeb heev thiab, txawm hais tias nws yuav zoo li nyuaj me ntsis, tab sis yooj yim to taub ntawm peb lub cev. Ntawd yog (Ascending Aorta) . Hais yooj yim xwb, qhov no yog thawj feem ntawm cov hlab ntsha tseem ceeb, (Aorta) , uas pib ntawm peb lub plawv thiab faib cov ntshav mus rau tag nrho lub cev. Nws zoo li daim uas tau teeb tsa hauv cov kav dej tseem ceeb uas coj dej los ntawm lub taub dej mus rau hauv tsev. Yog li, cia peb saib seb qhov no (Ascending Aorta) yog dab tsi, muaj dab tsi tshwm sim rau nws, nws tuaj yeem ua rau muaj kab mob dab tsi, thiab yuav ua li cas kom nws noj qab haus huv.

(Ascending Aorta) yog dab tsi? Nws ua rau dab tsi?

Xav txog tias peb lub cev zoo li lub nroog loj. Txhua lub tsev, txhua lub khw, txhua qhov chaw hauv lub nroog no xav tau dej. Ib yam li ntawd, txhua lub cell hauv peb lub cev xav tau cov ntshav huv, muaj oxygen. Leej twg tso cov ntshav no thoob plaws lub cev? Peb lub plawv. Cov ntshav uas lub plawv tso tawm raug nqa thoob plaws lub cev los ntawm cov hlab ntsha loj tshaj plaws (Aorta) , lossis aorta loj.

Tam sim no qhov no (Aorta) muaj ntau qhov chaw.

1. (Ascending Aorta): Qhov no yog qhov uas nce mus rau saum toj thaum nws tawm hauv lub chamber tseem ceeb uas hu ua Left Ventricle ntawm sab laug ntawm lub plawv. Qhov no yog peb tus thawj coj hnub no.

2. (Aortic Arch): Ces lub raj no khoov rau saum toj zoo li tus kov ntawm tus pas ntoo. Nws hu ua (Aortic Arch).

3. (Descending Aorta): Tom qab ntawd lub raj no mus rau hauv qab, hla lub hauv siab, hla lub plab. Qhov ntawd hu ua (Descending Aorta).

Yog li, lub luag haujlwm tseem ceeb ntawm (Ascending Aorta) yog coj cov ntshav uas muaj oxygen ntau uas lub plawv nqus thiab pib faib nws mus rau (Aortic Arch) thiab los ntawm qhov ntawd mus rau tag nrho lub cev. Tshwj xeeb, ob lub hlab ntsha tseem ceeb heev hu ua Coronary Arteries uas muab ntshav rau lub plawv pib los ntawm qhov no (Ascending Aorta). Xav txog, lub twj tso dej kuj xav tau dej los ua haujlwm, yog li ntawd nws ua haujlwm li cas.

Qhov no (Ascending Aorta) nyob qhov twg? Nws zoo li cas?

Qhov no (Ascending Aorta) nyob hauv peb lub hauv siab, tshwj xeeb yog pob txha loj nyob hauv nruab nrab ntawm lub hauv siab, tom qab (Sternum) , sab laug ntawm lub plawv. Nws txuas ncaj qha rau (Left Ventricle) ntawm lub plawv thiab nthuav dav mus rau sab saud.

Yog saib ntawm sab nraud, tag nrho cov aorta zoo li ib tug pas me me xwb. Lub aorta ascending yog qhov luv tshaj plaws ntawm cov pas uas pib ze ntawm lub plawv thiab nce mus rau saum. Lub aortic arch yog qhov uas khoov zoo li lub tes tuav ntawm cov pas.

Feem ntau, lub plawv Ascending Aorta ntev li ntawm 5 txog 8 centimeters (kwv yees li 2 txog 3 ntiv tes) thiab dav li ntawm 3 txog 4 centimeters. Nws maj mam txo qhov dav thaum nws txav mus rau hauv siab.

Cov feem ntawm Ascending Aorta yog dab tsi? Nws tsim li cas?

Tag nrho cov aorta yog muab faib ua ob qhov tseem ceeb: lub thoracic aorta thiab lub plab aorta.Cov Aorta (Ascending Aorta), Aortic Arch (Aortic Arch), thiab Descending Aorta (Descending Aorta) sib koom ua ke los ua Thoracic Aorta (Thoracic Aorta).

Lub Ascending Aorta pib ze ntawm lub Aortic Heart Valve, uas nyob tom qab lub Left Ventricle. Lub Aortic Valve no zoo li lub qhov rooj. Nws qhib thiab kaw kom cov ntshav ntws los ntawm lub Left Ventricle mus rau hauv Aorta. Lub Ascending Aorta xaus ua ntej lub Brachiocephalic Artery, thawj ceg loj uas ceg tawm ntawm Aortic Arch.

Ascending Aorta muaj ob feem tseem ceeb:

1. (Aortic Root): Qhov no yog lub hauv paus ntawm (Ascending Aorta), qhov ze tshaj plaws rau (Aortic Valve). Sab hauv no muaj cov qhov me me zoo li lub noob hu ua (Aortic Sinuses) . Cov no yog qhov chaw uas sab xis thiab sab laug (Coronary Arteries) (arteries uas muab ntshav rau lub plawv) pib. Qhov no kuj yog qhov chaw (Sinotubular Junction - STJ) nyob. STJ yog qhov chaw (Ascending Aorta) dhau los ua ib lub raj ib txwm muaj.

2. Tubular (Ascending Aorta): Qhov no pib tom qab STJ thiab txuas ntxiv mus txog Aortic Arch. Tsis muaj lwm cov hlab ntsha ceg tawm ntawm qhov no.

Ib yam li lwm qhov ntawm lub aorta, lub aorta nce mus yog ua los ntawm peb txheej ntawm cov ntaub so ntswg. Xav txog nws zoo li ib lub yeeb nkab, nrog peb txheej:

• (Tunica Intima): Qhov no yog txheej sab hauv tshaj plaws. Ntshav ntws los ntawm qhov no.
• (Media): Qhov no yog txheej nruab nrab. Nws muaj ntau cov fibers elastic. Cov no tso cai rau (Aorta) kom cog thiab ncab raws li cov ntshav siab. Txawm li cas los xij, dhau sijhawm, cov fibers no tuaj yeem ua rau tsis muaj zog thiab phab ntsa tuaj yeem ua nyias dua.
• (Adventitia): Qhov no yog txheej sab nraud tshaj plaws. Nws muaj cov hlab ntsha me me uas muab zaub mov rau phab ntsa ntawm (Aorta).

Hais yooj yim xwb, Ascending Aorta yog ib qho tseem ceeb heev, muaj zog 'ib daim yeeb nkab' uas thawj zaug txais ntshav los ntawm lub plawv thiab pib xa nws mus thoob plaws lub cev.

Cov kab mob dab tsi cuam tshuam rau Ascending Aorta?

Tu siab kawg li, qhov tseem ceeb no kuj tseem tuaj yeem ua rau muaj ntau yam kab mob. Cia peb saib seb cov kab mob tseem ceeb yog dab tsi:

• Aortic Aneurysms: Qhov no yog ib qho teeb meem uas tshwm sim ntau heev. Aneurysm yog qhov tsis muaj zog ntawm phab ntsa ntawm cov hlab ntsha, ua rau nws o zoo li lub npas. Ntau tshaj 50% ntawm aortic aneurysms hauv lub hauv siab tshwm sim hauv ascending aorta. Lawv tuaj yeem tshwm sim hauv cov hauv paus aortic lossis tubular ascending aorta. Aortic aneurysms yog cov mob uas ua rau tuag taus. Qhov no yog vim tias aneurysm tuaj yeem ua rau cov txheej ntawm cov hlab ntsha tawg - ib qho mob hu ua aortic dissection . Lossis, yog tias nws tawg tag nrho, kev los ntshav hnyav tuaj yeem tshwm sim hauv lub cev. Qhov no yog qhov xwm txheej ceev.

• (Kev mob plawv ntawm lub plawv Aortic Stenosis):Txawm hais tias lub Aortic Valve tsis yog ib feem ntawm Ascending Aorta, nws txuas nrog phab ntsa sab hauv ntawm Ascending Aorta. Aortic Stenosis yog qhov nqaim ntawm Aortic Valve ntawm Aortic Root thiab Left Ventricle. Qhov no ua rau lub plawv ua haujlwm hnyav dua los tso ntshav mus rau hauv Aorta. Qhov no tuaj yeem ua rau cov leeg plawv loj dua.

• (Aortic Valve Regurgitation): Qhov no tshwm sim thaum (Aortic Valve) tsis kaw zoo. Tom qab ntawd, es tsis txhob mus rau pem hauv ntej rau hauv (Aorta), ntshav rov qab mus rau hauv (Left Ventricle). Qhov no ua rau lub plawv nqus ntshav ntau dua li qub. Raws li lub sijhawm dhau mus, lub plawv tuaj yeem qaug zog. (Aortic Valve Regurgitation) kuj tuaj yeem tshwm sim vim yog (Ascending Aorta) nthuav dav.

• Bicuspid Aortic Valve (BAV): Ib txhia neeg yug los muaj ob daim nplooj hauv lawv lub aortic valve es tsis yog peb daim. Cov neeg uas muaj hom valve no muaj feem yuav mob aneurysms ntawm ascending aortic. BAV feem ntau tuaj yeem ua rau aortic stenosis, aortic regurgitation, lossis ob qho tib si.

• Cov Kab Mob Txuas: Cov neeg uas muaj cov kab mob xws li (Marfan Syndrome) , (Loeys-Dietz Syndrome) , thiab (Ehlers-Danlos Syndrome) tuaj yeem muaj teeb meem xws li (Aneurysms) vim tias phab ntsa ntawm (Aorta) tuaj yeem qaug zog.

• Kev Mob Hlwb: Cov mob xws li Giant Cell Arteritis thiab Penetrating Atherosclerotic Ulcers kuj tseem tuaj yeem ua rau puas tsuaj rau phab ntsa ntawm aorta.

Txawm hais tias cov tsos mob no yuav zoo li txaus ntshai me ntsis los xij, lawv tuaj yeem tswj tau yog tias paub ntxov thiab kho kom zoo .

Kuv yuav ua li cas thiaj li khaws kuv lub Ascending Aorta kom noj qab nyob zoo?

Tib yam koj ua kom koj lub plawv thiab cov ntshav ncig zoo kuj zoo rau kev noj qab haus huv ntawm Ascending Aorta.

• Noj zaub mov kom zoo thiab sib npaug: Noj cov khoom noj uas muaj sodium (ntsev), cholesterol, thiab cov rog saturated tsawg. Noj ntau txiv hmab txiv ntoo, zaub, cov nplej tag nrho, thiab cov fiber.
• Ua si nawv tsis tu ncua: Ua ib yam dab tsi xws li taug kev, khiav, lossis ua luam dej tsawg kawg 30 feeb hauv ib hnub. Nws ua rau lub plawv muaj zog thiab tswj cov ntshav siab.
• Tso tseg kev haus luam yeeb thiab cov khoom siv luam yeeb kiag li: Kev haus luam yeeb yog tus yeeb ncuab loj rau cov hlab ntsha. Nws ua rau phab ntsa ntawm lub aorta tsis muaj zog thiab ua rau muaj kev pheej hmoo ntawm aneurysms.
• Txo lossis tsum tsis txhob haus cawv: Kev haus cawv ntau dhau kuj tseem tuaj yeem ua rau cov ntshav siab thiab ua rau lub plawv thiab cov hlab ntsha puas tsuaj.
• Mus kuaj mob tsis tu ncua: Nws yog ib qho tseem ceeb heev uas yuav tsum mus kuaj mob tsis tu ncua raws li koj tus kws kho mob hais, tshwj xeeb tshaj yog tias koj muaj teeb meem xws li ntshav siab, roj cholesterol, ntshav qab zib, lossis yog tias ib tug neeg hauv koj tsev neeg muaj teeb meem aorta.

Kuv yuav tsum mus ntsib kws kho mob thaum twg?

Yog tias koj tau kuaj pom tias muaj Ascending Aortic Syndrome lossis lwm yam mob plawv, mus ntsib koj tus kws kho mob tam sim ntawd yog tias koj muaj cov tsos mob tshiab lossis yog tias koj cov tsos mob uas twb muaj lawm hnyav zuj zus.

Tsis tas li ntawd, yog tias koj muaj ib lossis ntau yam ntawm cov tsos mob hauv qab no, nws yuav yog ib qho cim qhia tias aneurysm tawg thiab koj yuav tsum nrhiav kev kho mob thaum muaj xwm txheej ceev tam sim ntawd:

• Kiv taub hau los yog tsaus muag (tsaim muag).
• Lub plawv dhia ceev ceev.
• Mob hauv siab lossis mob nraub qaum sab saud heev.
• Ua pa nyuaj.

Tsis txhob tso tseg cov tsos mob zoo li no. Kev kho mob thaum ntxov tuaj yeem cawm tau ib tug neeg txoj sia.
