Duplex ultrasound

Duplex ultrasound yog ib qho kev ntsuam xyuas kom pom ntshav txav li cas los ntawm koj cov hlab ntsha thiab leeg ntshav.

Duplex ultrasound ua ke:

• Tsoos ultrasound: Qhov no siv lub suab tsis muaj suab nrov uas thaws tawm ntawm cov hlab ntshav los tsim cov duab.
• Doppler ultrasound: Cov ntaub ntawv no lub suab tsis muaj suab xav txog cov khoom txav mus los, xws li ntshav, ntsuas lawv qhov ceev thiab lwm yam ntawm cov dej ntws li cas.

Nws muaj ntau ntau yam ntawm cov kuaj duplex ultrasound. Qee tus muaj xws li:

• Arterial thiab venous duplex ultrasound ntawm lub plab mog. Kev kuaj ntshav no kuaj xyuas cov ntshav kev ntshav thiab ntshav ntws hauv qhov chaw mob plab.
• Carotid duplex ultrasound saib ntawm cov carotid leeg hauv caj dab.
• Duplex ultrasound ntawm qhov kawg ua tau saib ntawm caj npab lossis ceg.
• Cov hlwv pob zeb hlaws duplex muaj tshuaj xyuas lub raum thiab lawv cov hlab ntshav.

Koj yuav tsum tau hnav khaub ncaws hnav kom zoo. Koj yuav tau pw ntawm lub rooj noj mov, thiab tus kws tshaj lij ultrasound yuav kis tus gel hla qhov chaw kuaj. Cov dej hiav txwv pab lub suab ntab tawm hauv koj cov ntaub so ntswg.

Ib qho wand, hu ua transducer, tau txav mus thaj chaw raug sim. Cov wand no xa tawm lub suab vuag. Khoos phib tawj ntsuas seb lub suab nthwv dej rov qab li cas, thiab hloov lub suab ua suab nrov rau hauv cov duab. Doppler tsim lub suab "zaws", uas yog lub suab ntawm koj cov ntshav txav los ntawm cov hlab ntsha thiab leeg ntshav.

Koj yuav tsum tau nyob twj ywm thaum lub sijhawm xeem. Tej zaum koj yuav raug hais kom pw ntawm cov kev ua haujlwm sib txawv hauv lub cev, lossis sib sib zog nqus pa thiab puag nws.

Qee zaum thaum lub zaws ultrasound ntawm ob txhais ceg, tus kws kho mob tuaj yeem suav lub pob taws-khiab mis taw (ABI). Koj yuav tsum tau hnav ris tsho ntshav siab rau ntawm koj txhais tes thiab ceg txhawm rau qhov kev ntsuas no.

Tus lej ABI tau txais los ntawm kev faib cov ntshav siab hauv pob taws los ntawm cov ntshav siab hauv caj npab. Tus nqi ntawm 0.9 lossis siab dua yog ib txwm.

Feem ntau, tsis muaj kev npaj rau qhov kev ntsuas no.

Yog tias koj muaj qhov ua pa ntawm koj lub plab, tej zaum yuav kom koj tsis txhob noj lossis haus tom qab ib tag hmo. Qhia tus neeg uas kuaj ntsuas ultrasound yog tias koj noj tshuaj, xws li ntshav ua kom nyias nyias. Cov no yuav cuam tshuam cov txiaj ntsig ntawm kev ntsuas.

Koj tuaj yeem hnov ​​qee qhov siab vim tias wand tau tsiv mus thoob lub cev, tab sis tsis muaj qhov tsis xis nyob feem ntau.

Duplex ultrasound tuaj yeem pom tias cov ntshav ntws mus rau ntau qhov chaw hauv lub cev li cas. Nws kuj tseem tuaj yeem qhia qhov dav ntawm txoj hlab ntsha thiab qhia qhov thaiv tau. Qhov kev sim no yog qhov kev xaiv tsis yooj yim dua li cov hlab ntsha thiab cov duab xis.

Duplex ultrasound tuaj yeem pab kuaj xyuas cov mob hauv qab no:

• Mob plab pob txha aneurysm
• Arterial occlusion
• Cov ntshav txhaws
• Carotid occlusive disease (Saib: Carotid duplex)
• Mob raum vascular
• Varicose leeg
• Venous tsis txaus

Lub raum duplex ultrasound tseem siv tau tom qab hloov chaw phais. Qhov no qhia tau hais tias lub raum tshiab ua haujlwm li cas.

Ib qho tshwm sim ib txwm yog ib txwm muaj ntshav ntws los ntawm cov leeg thiab hlab ntsha. Muaj ntshav siab ib txwm thiab tsis muaj phiajcim nqaim lossis thaiv ntawm cov hlab ntsha.

Qhov tshwm sim txawv txav yog nyob ntawm thaj chaw tshwj xeeb uas tau tshuaj xyuas. Qhov tshwm sim txawv txav yuav yog vim ntshav txhaws lossis ntshav hniav txhaws hauv txoj hlab ntshav.

Tsis muaj kev pheej hmoo.

Kev haus luam yeeb tuaj yeem hloov qhov tshwm sim ntawm kev sib chwv ntawm caj npab thiab ceg. Qhov no tshwm sim vim tias nicotine tuaj yeem ua rau cov hlab ntsha kom tuaj yeem (txwv).
