Ib tug phooj ywg ntawm peb lub siab: Cia peb kawm txog Circumflex Artery!

Koj puas tau xav tias peb lub plawv ua haujlwm zoo kawg li cas? Hauv lub plawv me me ntawd muaj ib lub network tseem ceeb heev ntawm cov hlab ntsha. Ib tug phooj ywg tshwj xeeb hauv lub network ntawd hu ua 'Circumflex Artery'. Koj tus kws kho mob kuj tseem yuav hu nws ua 'LCx' artery, lossis 'circ'. Yog li, hnub no, peb yuav tham txog 'Circumflex Artery' no kom ntxaws ntxiv?

"Circumflex Artery" yog dab tsi? Cia peb nkag siab yooj yim!

Zoo, xav txog nws li no. Muaj ob lub hlab ntsha tseem ceeb uas muab ntshav rau peb lub plawv. Lawv yog cov hlab ntsha sab laug thiab sab xis. Cov hlab ntsha sab laug tseem ceeb (Left Main Coronary Artery) ces faib ua ob ceg me me. Ib qho ntawm cov ceg ntawd yog cov hlab ntsha circumflex uas peb tab tom tham txog. Lwm ceg yog cov hlab ntsha sab laug pem hauv ntej nqis (LAD Artery). Cov kws kho mob hu qhov no ua kev sib cais ntawm cov hlab ntsha.

Yog li, lub luag haujlwm tseem ceeb ntawm '(Circumflex Artery)' no yog nqa cov ntshav huv thiab muaj oxygen mus rau sab nraub qaum thiab sab ntawm cov chav twj tso kua mis ntawm sab laug ntawm lub plawv. Nws zoo li lub yeeb nkab nqa dej mus rau lub twj tso kua mis.

Muaj dab tsi tshwm sim nrog qhov 'Circumflex Artery' no?

Peb muaj ib lub cev uas nqa cov ntshav thoob plaws peb lub cev, uas peb hu ua Circulatory System. Lub "Circumflex Artery" no yog ib txoj hlab ntshav tseem ceeb uas txuas nrog lub plawv hauv lub cev ntawd.

Qhov uas tshwm sim ntawm no yuav txawv me ntsis nyob ntawm txhua tus neeg lub cev . Txawm li cas los xij, rau txhua tus neeg, cov seem hauv qab no ntawm sab laug ntawm lub plawv tau txais cov ntshav nplua nuj oxygen los ntawm "Circumflex Artery":

• Sab laug Atrium - Qhov no yog chav sab laug sab saud ntawm lub plawv.
• Sab laug Ventricle - Qhov no yog lub chamber loj nyob rau sab laug qis ntawm lub plawv.
• Cov leeg nqaij papillary sab hauv lub ventricle sab laug.

Rau qee tus neeg, tab sis tsis yog txhua tus, qhov "Circumflex Artery" no muab ntshav mus rau lwm qhov tseem ceeb ntawm lub plawv. Qhov ntawd yog "Sinoatrial Node" ("SA Node"). Rau feem ntau ntawm cov neeg, txoj haujlwm no yog ua los ntawm cov hlab ntsha loj sab xis. Qhov "SA Node" no yog ib feem ntawm lub plawv lub zog hluav taws xob uas tswj peb lub plawv dhia. Cov kws kho mob kuj hu nws ua "natural pacemaker" ntawm lub plawv.

Yog li ntawd, qhov 'Circumflex Artery' no nyob qhov twg?

Peb twb hais lawm tias cov hlab ntsha sab laug ntawm peb lub plawv faib ua ob ceg. Qhov no yog qhov uas '(Circumflex Artery)' no pib. Nws nyob hauv txheej sab nraud ntawm lub plawv hu ua '(Epicardium).' Yog xav kom meej, nws mus ncig los ntawm ib lub kwj dej me me ntawm ob lub chav ntawm sab laug ntawm lub plawv.

Puas muaj lwm ceg ntawm cov hlab ntsha hu ua 'Circumflex Artery'?

Yog lawm, qhov '(Circumflex Artery)' no kuj muab cov ceg me me. Cov no hu ua 'Marginal Artery Branches'. Tus naj npawb ntawm cov ceg no tsis zoo ib yam rau txhua tus. Qee tus neeg tsuas muaj peb ceg mus rau sab hu ua 'Obtuse Marginal Branches'. Cov ceg me me no feem ntau mus raws sab nraud ntawm 'Left Ventricle', mus rau nws 'Apex'.

Hauv cov neeg tsawg tsawg xwb, qhov "Circumflex Artery" no muaj lwm ceg hu ua "Left Posterior Ventricular - LPV Artery". Txawm li cas los xij, rau cov neeg feem coob, qhov "LPV Artery" no (tseem hu ua "Posterolateral Artery") muaj lwm ceg hu ua "(Circumflex Artery)" los ntawm txoj hlab ntsha loj sab xis.

Coronary Arterial Dominance yog dab tsi?

Qhov no yog ib qho kev kawm tob me ntsis, tab sis cia peb sim nkag siab yooj yim. Cov hlab ntsha tseem ceeb uas xa cov ntshav mus rau txheej nqaij nruab nrab ('Myocardium') ntawm peb lub plawv yog 'Posterior Descending Artery' ('PDA'). Yog li, koj qhov kev txiav txim siab ntawm koj cov hlab ntsha coronary yog txiav txim siab los ntawm ceg hlab ntsha tseem ceeb twg xa cov ntshav mus rau '(PDA)' no hauv koj lub plawv.

Qhov no tuaj yeem tshwm sim hauv peb txoj hauv kev tseem ceeb:

• Kev ncig ntshav sab xis uas tswj tau: Qhov no yog yam uas feem ntau ntawm cov neeg (kwv yees li 85 ntawm 100) muaj. Ntawm no, PDA tau txais ntshav los ntawm cov hlab ntsha sab xis.
• Kev ncig ntshav sab laug tseem ceeb: Qhov no tshwm sim rau kwv yees li 1 ntawm 10 tus neeg. Ntawm no, PDA tau txais cov ntshav los ntawm Circumflex Artery lossis LAD Artery.
• Kev ncig ntshav sib npaug: Qhov mob no tshwm sim rau kwv yees li 2 ntawm 10 tus neeg. PDA tau txais ntshav los ntawm ob qho tib si txoj hlab ntsha sab xis thiab txoj hlab ntsha sab laug lossis LAD hlab ntsha.

Xav txog nws zoo li cov kav dej loj uas xa dej mus rau lub tsev. Muaj tej lub tsev tsuas tau dej los ntawm cov kav dej sab xis xwb, qee lub los ntawm sab laug, thiab qee lub los ntawm ob sab.

Puas muaj lwm cov hlab ntsha hom 'Circumflex' hauv peb lub cev?

Yog lawm, ntxiv rau "Circumflex Artery" hauv lub plawv, muaj lwm hom hlab ntsha hauv peb lub cev hu ua lub npe no.

• Cov hlab ntsha Femoral Circumflex: Cov no yog ob ceg tob uas ceg tawm ntawm cov hlab ntsha tseem ceeb hauv peb lub duav, Femoral Artery. Cov hlab ntsha Femoral nqa cov ntshav los ntawm lub plab mus rau ob txhais ceg. Qee zaum, thaum lub sijhawm phais mob plawv, cov kws kho mob coj Circumflex Artery los ntawm lub duav thiab siv nws ua ib qho graft.
• Cov hlab ntsha Circumflex ntawm Humeral:Cov no raug faib los ntawm '(Axillary Artery)' hauv peb thaj tsam qhov tsoob. '(Axillary Artery)' no yog qhov uas nqa cov ntshav los ntawm lub hauv siab mus rau lub xub pwg nyom thiab caj npab. Tshwj xeeb, peb pob txha caj npab sab saud ('Humerus') feem ntau yog cov ntshav los ntawm '(Posterior Humeral Circumflex Artery)' no.

Cov kab mob dab tsi cuam tshuam rau 'Circumflex Artery'?

Ib yam li lwm cov hlab ntsha hauv lub plawv, cov hlab ntsha circumflex kuj tuaj yeem raug cuam tshuam los ntawm ib yam mob hu ua kab mob plawv (CAD). Qhov no yog thaum cov rog (plaque) sib sau ua ke hauv cov hlab ntsha, thaiv nws. Nws zoo li xeb txhaws cov kav dej.

Qhov kev sib sau ua ke ntawm cov plaque thiab cov phab ntsa ntawm cov hlab ntsha no hu ua atherosclerosis, uas txhais tau tias "cov hlab ntsha tawv" lossis "cov hlab ntsha tawv." Yog tias tus mob CAD no tsis raug kho kom zoo, nws ua rau muaj kev pheej hmoo ntawm kev mob txaus ntshai xws li mob plawv nres, mob plawv tsis ua haujlwm, thiab mob hlwb .

Cov tsos mob ntawm kev txhaws hauv 'Circumflex Artery' yog dab tsi?

Thaum cov ntshav ntws tsawg dua vim yog cov hlab ntsha nqaim, mob hauv siab tuaj yeem tshwm sim. Qhov no hu ua "Angina". Qhov mob "Angina" no tuaj yeem ua rau mob plawv nres. Qhov no yog xwm txheej ceev hauv kev kho mob, yog li koj yuav tsum hu rau 911 tam sim ntawd.

Vim tias qhov txhaws ntawm cov hlab ntsha circumflex kuj yog ib feem ntawm CAD, cov tsos mob zoo sib xws. Tej zaum koj yuav muaj tej yam zoo li no:
