Qee zaum tus neeg sab nrauv zoo li noj qab nyob zoo, tab sis xav tias tsis muaj zog thiab muaj kev kiv taub hau. Ib tus kws kho mob paub txog qhov no yuav xav tias cov ntshav tsis txaus rau lub hlwb thiab hais kom kuaj xyuas cov hlab ntsha brachiocephalic. Qhov kev ntsuam xyuas no ua li cas thiab ua rau tus neeg muaj tus mob zoo li cas?

Cov hlab ntsha brachiocephalic yog dab tsi?

Peb tab tom tham txog cov hlab ntsha tseem ceeb hauv cov ntshav muab rau cov nqaij mos ntawm lub taub hau thiab lub hlwb. Txhawm rau kom lub paj hlwb tau txais cov ntshav tsim nyog, carotid, brachiocephalic thiab sab laug ceg ntawm cov hlab ntsha subclavian tau koom nrog hauv nws cov khoom. Tab sis nws yog cov hlab ntsha brachiocephalic uas ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tseem ceeb no. Lwm ob txoj hlab ntsha tuaj yeem suav tias yog txoj hauv kev ntxiv ntshav, tab sis yog tias lub ntsiab tsis ua haujlwm, lawv yuav tsis tiv nrog txoj haujlwm.

Lub voj voog Wellisian yog dab tsi?

Carotid, brachiocephalic thiab sab laug ceg ntawm cov hlab ntsha subclavian ntawm lub hauv paus ntawm lub hlwb tsim lub voj voog vicious, nws yog hu uaWellisiev. Lub voj voog yog lub luag haujlwm rau cov khoom sib xws ntawm txhua qhov chaw ntawm lub hlwb nrog cov ntshav tshiab. Nws suav nrog cov hlab ntsha uas muab ntshav rau sab xis ntawm lub xub pwg nyom. Yog hais tias lub patency ntawm qee qhov ntawm lub voj voog raug cuam tshuam, tag nrho cov kab ke raug yuam kom rov tsim kho, vim tias qhov kev faib tawm ntawm cov ntshav cuam tshuam. Xws li kev ua txhaum ntawm cov ntshav cerebral tuaj yeem ua rau muaj qhov tshwm sim loj heev, piv txwv li, ua rau mob stroke.

Dab tsi yog atherosclerosis?

Ntau zaus cov hlab ntsha brachiocephalic raug kev txom nyem los ntawm atherosclerosis. Tus kab mob no raug cais raws li cov txheej txheem ntev. Nws yog qhia nyob rau hauv deposition ntawm cov cholesterol atheromatous plaques nyob rau hauv lub lumen ntawm lub hlab ntsha. Plaques ua rau kev loj hlob ntawm cov ntaub so ntswg thiab calcification ntawm cov phab ntsa elastic, raws li qhov tshwm sim ntawm lub nkoj deformed, nqaim, thiab qee zaum tag nrho txhaws.

Tshuaj qhia qhov txawv ntawm ob hom kab mob:

  1. Neurostenosing, uas yog, atherosclerosis, uas cov cholesterol plaques loj hlob ntev yam tsis thaiv lub lumen ntawm lub nkoj.
  2. Stenosing, uas yog, atherosclerosis nrog kev loj hlob ntawm cov plaques. Hom no muaj kev phom sij ntau dua, vim nws tuaj yeem thaiv cov ntshav ntws tag nrho.

Kev kho mob atherosclerosis nyob ntawm hom thiab theem ntawm tus kab mob.

Diagnosis

Txhawm rau lees paub lossis tsis lees paub qhov ua rau tus neeg mob noj qab haus huv tsis zoo, tus kws kho mob tau sau ntawv rau kev kawm txog cov hlab ntsha brachiocephalic. Rau cov hom phiaj no, cov cuab yeej siv niaj hnub no yog siv uas tsis cuam tshuam nrog X-ray irradiation, piv txwv li, ultrasound thiab ultrasound lossis sib nqus.resonance angiography, uas siv tus neeg sawv cev sib txawv thiab x-rays.

Surveying

Ultrasound ntawm brachiocephalic hlab ntsha yog suav tias yog txoj kev tshawb fawb zoo tshaj plaws. Ultrasonic nthwv dej ua rau nws muaj peev xwm txiav txim siab ob qho tib si lub xeev anatomical thiab qib ntawm patency ntawm cov hlab ntsha. Cov txheej txheem yog qhov yooj yim heev thiab tsis xav tau kev npaj nyuaj los ntawm tus neeg mob. Kev ntsuam xyuas yog ua nrog ib lub cuab yeej tshwj xeeb. Tus neeg mob muab tso rau ntawm lub rooj zaum, ib tug menyuam yaus muab tso rau hauv qab lub caj dab. Raws li qhov kev thov ntawm tus kws kuaj mob, lub taub hau yuav tsum tig mus rau qhov kev taw qhia rov qab rau lub sensor.

UZDG

Nyob rau yav dhau los, cov hlab ntsha brachiocephalic tau kuaj los ntawm dopleography nkaus xwb. Doppler ua rau nws muaj peev xwm txiav txim siab qhov kev taw qhia thiab ceev ntawm cov ntshav khiav, tab sis tsis muaj peev xwm ntsuas qhov kev hloov pauv ntawm cov phab ntsa vascular. Lub sensor xa ib nthwv dej uas tau cuam tshuam los ntawm cov ntshav cov ntsiab lus. Txawm hais tias nws tsis zoo tag nrho, cov txheej txheem tau cawm ntau tus tib neeg txoj sia, tso cai rau lub sijhawm rov qab los ntawm cov ntshav mus rau lub hlwb. Thaum ua ultrasound ntawm cov hlab ntsha brachiocephalic, cov zaub tau pom cov duab thiab cov spectrum, thiab tsis yog cov duab ntawm cov hlab ntsha. Yog li, tus kws kuaj mob tau txais cov ntaub ntawv tsis tiav txog tus neeg mob tus mob.

Ntau tus kws kho mob tseem siv txoj kev "dig muag dopleography" niaj hnub no, vim tias nws tsis xav tau cov nqi siab los ntawm cov tsev kho mob lossis cov neeg mob. Txoj kev qhia tsuas yog kev ua txhaum cai tag nrho, tab sis siv sijhawm me ntsis. Yog tias pom muaj teeb meem loj thaum kuaj cov hlab ntsha brachiocephalic, tus neeg mob tau txais kev teem sijhawm ntxivrau duplex lossis triplex scanning.

Duplex Scan

Hom kev kuaj xyuas ntawm cov hlab ntsha ntawm lub caj dab thiab lub taub hau kuj yog raws li ultrasonic tsis. Cov txheej txheem duplex hu ua vim qhov tseeb tias nws ua ke ob-dimensional ultrasound nrog Doppler hom. Cov txheej txheem tso cai rau koj kom pom tsis tau tsuas yog daim duab thiab spectrum ntawm kev txav, tab sis kuj kom tau txais daim duab ob sab ntawm lub nkoj brachiocephalic. Qhov screen qhia cov yam ntxwv ntawm cov qauv ntawm cov hlab ntsha thiab cov ntaub so ntswg. Txhawm rau kom yooj yim, kev txav ntawm cov ntshav los ntawm cov hlab ntsha yog pom hauv cov ntshav liab, thiab cov ntshav venous hauv xiav.

Duplex scanning ntawm brachiocephalic hlab ntsha ntsuas cov hauv qab no tsis:

  • ntshav ntws ntim;
  • qhov nrawm ntawm nws txoj kev nce qib hauv cov nkoj;
  • yam ntxwv ntawm cov qauv ntawm cov hlab ntsha thiab cov leeg;
  • obstacles to blood flow;
  • mob ntawm cov ntaub so ntswg uas nyob ib sab.

Txoj kev tso cai rau koj los txiav txim siab txog ntau yam vascular pathologies ntawm cov hlab ntsha brachiocephalic, uas suav nrog: atherosclerosis, ntau yam vasculitis, angiopathy, cov qauv tsis xws luag, vascular deformities, aneurysms txuas fistulas ntawm venous thiab arterial ntshav khiav, thrombosis thiab ntau ntxiv..

Triplex Study

Koj puas xav tias qhov no yog kev hloov pauv ntawm kev kawm txog cov hlab ntsha hauv caj dab thiab lub taub hau? Qhov tseeb, tag nrho qhov sib txawv tsuas yog nyob ntawm tus naj npawb ntawm cov qauv ntsuas. Muaj 2 hom kev ntsuam xyuas ntawm qhov screen thaum lub sij hawm kuaj duplex, thiab 3 thaum lub sij hawm kuaj triplex, nws yuav yooj yim dua rau tus kws kho mob saib cov duab,tab sis qhov zoo ntawm kev kuaj mob los ntawm qhov no nce me ntsis. Yog tias tus nqi ntawm cov txheej txheem tsis ua lub luag haujlwm loj rau tus neeg mob, nws tuaj yeem raug kuaj xyuas triplex. Tab sis yog hais tias tus nqi tseem ceeb, ces kev ntsuam xyuas duplex yuav txaus los txiav txim qhov tseeb.

Ntau yam khoom siv niaj hnub no muaj 3D qauv ua haujlwm. Qhov tseeb, qhov no yog daim duab zoo nkauj kim uas tuaj yeem ua rau kev txaus siab. Qhov kev kuaj no tsis muab cov ntaub ntawv ntxiv rau tus kws kho mob.

Lub sijhawm npaj thiab contraindications

Tsis xav tau kev npaj tshwj xeeb rau hnub ua ntej txheej txheem. Kev kuaj ultrasound ntawm cov hlab ntsha brachiocephalic tuaj yeem ua tau tam sim tom qab lub sijhawm teem tseg, vim tias tsis muaj zaub mov lossis lub cev ntawm tus neeg mob muaj kev cuam tshuam zoo rau qhov tshwm sim. Qhov tsuas yog qhov tsim nyog tso tseg yog siv cov khoom noj lossis dej haus uas ua rau vasospasm. Cov no yog cov tshuaj yej thiab kas fes zoo tib yam, Pepsi lossis Cola haus, txhua hom dej haus, cawv thiab luam yeeb. Yog tias tus neeg mob noj cov tshuaj uas kws kho mob tau sau tseg, tsis tas yuav ncua lub sijhawm teem tseg.

Ultrasound ntawm cov hlab ntsha tseem ceeb uas muab cov ntshav rau lub hlwb tuaj yeem ua tau txawm tias cov niam cev xeeb tub thiab lactating niam. Contraindications rau kev tshawb fawb tsuas yog ib tug tshiab caj dab raug mob los yog pustular lesions nyob rau hauv cheeb tsam no. Qhov no yog vim lub fact tias lub sensor yuav ua rau lub caj dab thiab cov gel yuav siv tau. Qhov kev raug mob no tuaj yeem ua rau mob hnyav lossis kis kab mob los ntawm daim tawv nqaij.

Dab tsi yog muab rautxhais tes rau tus neeg mob

Tus kws tshuaj ntsuam xyuas yuav tsum tau muab rau tus neeg mob cov lus xaus piav qhia txog lub xeev ntawm cov hlab ntsha kuaj. Cov lus xaus yuav tsum muaj ntau cov ntaub ntawv tseem ceeb rau kev kuaj mob. Cov no yog qhov loj ntawm cov hlab ntsha, thiab qhov ceev ntawm cov ntshav khiav, thiab lwm yam tsis. Nws raug nquahu kom xa cov duab ntawm thaj chaw teeb meem pom los ntawm tus kws kuaj mob.
