Carotid ob lub tsev

Carotid duplex yog txoj kev kuaj ntshav ultrasound uas qhia pom tias cov ntshav khiav zoo li cas hauv cov hlab ntsha carotid. Cov hlab ntsha carotid nyob rau hauv lub caj dab. Lawv muab ntshav ncaj qha rau lub hlwb.

Ultrasound yog ib txoj kev tsis muaj kev mob uas siv cov suab ua suab los tsim cov duab sab hauv ntawm lub cev. Qhov ntsuas yog ua tiav hauv chav ntsuas ntshav lossis chav ntsuas hluav taws xob.

Kev ntsuas yog ua raws li hauv qab no:

• Koj pw ntxeev tiaj. Koj lub taub hau tau txais kev txhawb kom ua kom nws txav mus los. Tus kws tshaj lij ultrasound siv dej pleev xim rau gel rau koj lub caj dab kom pab nrog kis ntawm cov suab nthwv dej.
• Tom ntej no, tus kws tshaj lij txav ib lub xov paj hu ua transducer rov qab thiab thaj chaw.
• Cov cuab yeej xa suab xa mus rau cov hlab ntsha hauv koj lub caj dab. Lub suab ntsaj bounce tawm ntawm cov hlab ntshav thiab tsim daim duab lossis duab ntawm sab hauv ntawm cov hlab ntsha.

Tsis muaj kev npaj tsim nyog.

Koj tuaj yeem hnov ​​qee qhov siab vim tias lub zog hloov mus ntawm koj lub caj dab. Lub siab yuav tsum tsis txhob ua kom muaj mob. Koj kuj tuaj yeem hnov ​​lub suab "whooshing". Qhov no yog qhov qub.

Qhov kev kuaj no tshawb xyuas cov ntshav txaus hauv cov hlab ntsha carotid. Nws tuaj yeem tshawb pom:

• Ntshav (thrombosis)
• Nqaim hauv cov hlab ntsha (stenosis)
• Lwm qhov ua rau txhaws ntawm cov hlab ntsha carotid

Koj tus kws kho mob yuav xaj kom ntsuas yog tias:

• Koj tau mob stroke lossis trans ischemic nres (TIA)
• Koj yuav tsum tau rov soj ntsuam dua vim tias koj cov carotid leeg tau pom tias txoj kev nqaim yav dhau los lossis koj tau raug phais ntawm txoj leeg ntshav
• Koj tus kws kho mob hnov ​​suab txawv txawv hu ua bruit hla lub caj pas carotid. Qhov no txhais tau tias cov leeg leeg nqaim.

Cov txiaj ntsig yuav qhia rau koj tus kws kho mob li cas qhib lossis nqaim ntawm koj cov carotid hlab ntsha. Piv txwv, cov hlab ntsha yuav ua kom 10% nqaim, 50% nqaim, lossis 75% nqaim.

Ib qho txiaj ntsig tshwm sim txhais tau hais tias tsis muaj teeb meem nrog cov ntshav khiav hauv cov hlab ntsha carotid. Txoj hlab ntshav dawb tsis muaj qhov thaiv ntxiv, kev nqaim, lossis lwm yam teeb meem.

Qhov txawv txav tshwm sim txhais tau hais tias cov leeg ntshav tau nqaim, lossis qee yam hloov pauv cov ntshav hauv lub cev carotid. Qhov no yog lub cim ntawm atherosclerosis lossis lwm yam kev mob txog ntshav hlab ntsha.

Feem ntau, txoj kev sib tw ntawm txoj leeg muaj tsawg dua, qhov ntau dua koj yuav muaj mob stroke.

Nyob ntawm qhov txiaj ntsig tau, koj tus kws kho mob yuav xav kom koj:

• Xav txog kev phais mob
• Muaj kev sim ntxiv (xws li cerebral angiography, CT angiography, thiab Magnetic resonance angiography)
• Ua raws li kev noj zaub mov zoo rau lub cev thiab kev ua neej zoo los tiv thaiv qhov tawv ntawm cov hlab ntsha
• Rov ua qhov ntsuas nyob rau yav tom ntej

Nws tsis muaj kev pheej hmoo nrog kev ua tus txheej txheem no.
