Dab tsi yog Doppler ultrasound?

Doppler ultrasound yog kev sim ntsuas uas siv lub suab tsis ua suab los qhia cov ntshav txav los ntawm cov hlab ntshav. Ib qho zaus tsis tu ncua tseem siv lub suab tsis ua suab los tsim cov duab ntawm cov qauv hauv lub cev, tab sis nws tsis tuaj yeem pom ntshav txaus.

Doppler ultrasound ua haujlwm los ntawm kev ntsuas cov suab nrov uas tau xav txog los ntawm cov khoom txav, xws li ntshav liab. Qhov no paub li Doppler effect.

Nws muaj ntau yam kev ntsuam xyuas Doppler ultrasound. Lawv suav nrog:

  • Xim Doppler. Hom Doppler no siv lub khoos phis tawm los pauv suab yoj suab mus rau hauv cov xim sib txawv. Cov xim no qhia txog kev nrawm thiab kev coj ntawm cov ntshav khiav hauv lub sijhawm.
  • Lub Zog Doppler, hom xim dua tshiab Doppler. Nws tuaj yeem muab cov ncauj lus qhia ntxiv ntawm cov ntshav txaus dua li qauv xim Doppler. Tab sis nws tsis tuaj yeem qhia cov kev taw qhia ntawm cov ntshav ntws, uas tuaj yeem yog qhov tseem ceeb hauv qee kis.
  • Spectral Doppler. Qhov ntsuam xyuas no qhia cov ntshav ntws cov ntaub ntawv ntawm daim duab piav qhia, tsis yog cov duab xim. Nws tuaj yeem pab qhia tawm ntau npaum li cas ntawm cov hlab ntshav txhaws.
  • Duplex Doppler. Txoj kev kuaj no siv cov qauv ntsuas hluav taws xob (ultrasound) coj los siv cov duab ntawm cov hlab ntsha thiab cov khoom nruab nrog cev. Tom qab ntawd lub khoos phis tawm hloov cov duab mus rau hauv cov teeb, raws li hauv Doppler spectral.
  • Nruam yoj Doppler. Hauv qhov kev ntsuas no, cov suab nrov tau xa thiab tau txais txuas ntxiv. Nws tso cai rau ntau tshaj qhov tseeb ntsuas ntawm cov ntshav uas ntws ntawm qhov nrawm dua.

Lwm lub npe: Doppler ultrasonography


Nws siv rau dab tsi?

Kev ntsuam xyuas Doppler yog siv los pab cov kws kho mob kom pom tias koj muaj tus mob uas txo lossis thaiv koj cov ntshav cov ntshav. Nws kuj tseem siv los pab txheeb xyuas qee cov kab mob hauv lub plawv. Qhov kev ntsuam xyuas yog feem ntau siv rau:

  • Xyuas lub plawv muaj nuj nqi. Nws feem ntau ua nrog ib daim electrocardiogram, ib qho kev sim uas ntsuas lub teeb liab hluav taws xob hauv plawv.
  • Saib rau blockages hauv cov ntshav txaus. Cov ntshav txhaws hauv ob txhais ceg tuaj yeem ua rau tus mob hu ua sib zog nqus ntshav muaj zog (DVT).
  • Tshawb xyuas cov ntshav kev puas tsuaj thiab rau qhov tsis xws luag hauv tus qauv ntawm lub siab.
  • Saib kom pom txoj kev nqaim ntshav. Cov hlab ntsha nqaim nyob hauv caj npab thiab txhais ceg txhais tau tias koj muaj tus mob hu ua peripheral arterial (PAD). Nqa cov hlab ntsha hauv caj dab tuaj yeem txhais tau tias koj muaj ib qho mob hu ua carotid artery stenosis.
  • Saib xyuas ntshav ntws tom qab kev phais.
  • Kuaj ntshav txaus hauv tus poj niam cev xeeb tub thiab nws tus menyuam hauv plab.

Vim li cas kuv thiaj xav tau Doppler ultrasound?

Koj yuav xav tau Doppler ultrasound yog tias koj muaj cov tsos mob txo qis ntshav lossis lub plawv mob. Cov tsos mob txawv raws tus mob ua rau muaj teeb meem. Qee qhov kev mob ntshav ntws thiab cov tsos mob tshwm sim hauv qab no.


Cov tsos mob ntawm tus mob hlab ntsha hlwb (PAD) suav nrog:

  • Loog lossis tsis muaj zog hauv koj txhais ceg
  • Mob ntswj mob hauv koj lub duav lossis txhais ceg leeg thaum taug kev lossis nce ntaiv
  • Kev hnov ​​txias nyob hauv koj sab ceg lossis taw
  • Hloov xim thiab / lossis tawv nqaij ci rau ntawm koj txhais ceg

Cov tsos mob ntawm lub plawv muaj xws li:

  • Ua tsis taus pa
  • O hauv koj txhais ceg, ko taw, thiab / lossis plab
  • Nkees

Koj kuj tseem xav tau Doppler ultrasound yog tias koj:

  • Mob stroke lawm. Tom qab mob hlab ntsha tawg, koj tus kws saib xyuas kev noj qab haus huv yuav xaj ib qho tshwj xeeb ntawm Doppler kuaj, hu ua transcranial Doppler, los kuaj ntshav ntws mus rau lub hlwb.
  • Muaj kev raug mob rau koj cov hlab ntshav.
  • Raug kho rau cov ntshav khiav tsis zoo.
  • Cev xeeb tub thiab koj tus kws kho mob xav tias koj lossis koj tus menyuam hauv plab yuav muaj teeb meem ntshav ntws. Koj tus kws kho mob yuav xav tias muaj teeb meem yog tias koj tus menyuam hauv plab tseem me dua nws yuav tsum nyob rau theem ntawm cev xeeb tub no lossis yog koj muaj qee yam mob. Cov no suav nrog cov kab mob hauv cov ntshav lossis preeclampsia, ib hom ntshav siab uas cuam tshuam rau cov poj niam cev xeeb tub.

Dab tsi tshwm sim thaum Doppler ultrasound?

Doppler ultrasound feem ntau suav nrog cov kauj ruam hauv qab no:


  • Koj yuav tau pw ib lub rooj, tso cov cheeb tsam ntawm koj lub cev uas raug sim.
  • Tus kws kho mob yuav xa ib qho gel tshwj xeeb rau ntawm daim tawv nqaij hla thaj chaw ntawd.
  • Tus muab kev pab cuam yuav txav cov khoom siv zoo li wand, hu ua transducer, hla thaj chaw.
  • Cov cuab yeej xa suab tsis mus rau koj lub cev.
  • Kev txav txav ntawm cov qe ntshav ua rau kev hloov lub suab hloov suab. Koj tuaj yeem hnov ​​cov lus nrov nrov los ntawm kev hais lus lossis suab nrov mem tes thaum lub sijhawm txheej txheem.
  • Cov vuag tau kaw tseg thiab hloov mus ua duab lossis duab rau ntawm ib lub monitor.
  • Tom qab sim tas lawm, tus kws kho mob yuav so cov gel tawm ntawm koj lub cev.
  • Qhov kev xeem yuav siv li 30-60 feeb los ua kom tiav.

Kuv puas yuav tau ua ib yam dab tsi txhawm rau npaj rau qhov kev xeem?

Txhawm rau npaj rau Doppler ultrasound, koj yuav tsum:

  • Tshem cov khaub ncaws thiab cov hniav nyiaj hniav kub ntawm thaj chaw ntawm lub cev uas tau mus kuaj.
  • Zam kev haus luam yeeb thiab lwm cov khoom lag luam uas muaj cov nicotine mus txog ob xuab moos ua ntej koj txoj kev kuaj mob. Nicotine ua rau cov hlab ntsha nqaim, uas tuaj yeem cuam tshuam koj cov txiaj ntsig.
  • Rau qee yam kev ntsuam xyuas Doppler, koj yuav raug thov kom yoo mov (tsis txhob noj lossis haus) rau ob peb teev ua ntej ntsuas.

Koj tus kws kho mob yuav qhia rau koj paub yog tias koj xav tau ua ib yam dab tsi los npaj rau qhov kev sim koj.

Puas muaj kev pheej hmoo rau kev kuaj?

Tsis muaj qhov paub tias yuav ua kom muaj Doppler ultrasound. Nws kuj tseem pom tias muaj kev nyab xeeb thaum cev xeeb tub.

Cov txiaj ntsig li cas?

Yog tias koj cov txiaj ntsim tau tsis zoo, nws yuav txhais tau tias koj muaj:

  • Ib qhov txhaws lossis ntshav hauv cov leeg ntshav
  • Nqaim ntshav hlab ntsha
  • Kev ntshav khiav tsis zoo
  • Aneurysm, zais pa zoo li zais hauv cov hlab ntsha. Nws ua rau cov hlab ntsha plam thiab nyias. Yog hais tias lub phab ntsa ua heev dhau, cov leeg tuaj yeem tuaj yeem ua rau mob, ua rau kom muaj sia nyob ntawm ntshav.

Cov txiaj ntsig kuj tseem tuaj yeem ua qhia tau yog tias muaj ntshav khiav tsis zoo hauv tus menyuam mos hauv plab.

Lub ntsiab lus ntawm koj cov txiaj ntsig tau zoo nyob ntawm seb thaj chaw ntawm lub cev tau kuaj li cas. Yog koj muaj lus nug txog koj cov txiaj ntsig, nrog koj tus kws kho mob tham.
