Zoo rau lub doppler scan

Vascular doppler ultrasound ntawm lub qis extremities yog ib tug muaj kev ruaj ntseg thiab mas tuav txoj kev uas yuav ntsuam xyuas cov ntshav khiav. Nws yuav siv tsis tau tsuas yog rau kev tshawb nrhiav tus kab mob, thaum cov ntshav khiav yog ho tsis hnov, tab sis kuj los mus txiav txim ntawm qhov pib ntawm tus kab mob ntawm ib theem thaum muaj kev soj ntsuam tej yam tshwm sim yog tsis tuaj kawm ntawv.

Cov qauv no yog raws li nyob rau hauv lub fact tias cov ultrasonic yoj yog reflected los ntawm tsiv khoom. Qhov no hloov lub zaus ntawm lub outputted teeb liab. Siv doppler ultrasound yuav txiav txim nyob rau hauv uas cov kev taw qhia thiab nyob li cas ceev yog tsiv ntshav, mus saib lub atherosclerotic stenosis, saib mem. Tsis tas li ntawd, qhov no txoj kev tso cai rau peb los laij rau tus feeb ntshav txaus thiab qhia hais tias tus daig cov hlab ntsha. Nrog nws saib efficiency collateral ncig.

Tab sis qhov tseem tuav yog ob lub tsev PP, nyob rau hauv uas sib nrug los ntawm cov pa ultrasonography thiab ua ib qho ultrasound. Nrog rau tom kawg txoj kev, koj yuav saib tau lub anatomical nta ntawm lub vascular qauv.

Qhov ntawd yuav ntsib ib tug kws kho mob thaum lub sij hawm ntawm txoj kev

Thaum lub sij hawm ultrasonography ntawm lub qis extremities specialist yuav paub tej yam kev ua txhaum. Txoj kev tshawb no muab ib lub sij hawm kom to taub ua li cas rau cov hlab ntsha, thiab tsim kom muaj ib qho tseeb kuaj mob. Yog li, thaum lub sij hawm soj ntsuam, koj yuav:

- xyuas seb tus mem tes yoj hloov;

- diagnosing poob ntshav txaus nyob rau hauv tej cheeb tsam;

- pom hais tias cov ntshav khiav yog sis tsis ncaj;

- sau lub retrograde ntshav txaus nyob rau hauv lub sij hawm ntawm so, los yog, conversely, loads;

- saib cov kev hloov nyob rau hauv pob luj taws-brachial Performance index: ib tug Performance index uas yog muab xam rau ntawm tus piv ntawm lub siab nyob rau hauv cov leeg ntawm ceg nyob ze ntawm lub pob luj taws thiab brachial leeg;

- sau hais tias muaj yog txawv txav paug ntawm cov ntshav rau perforating leeg;

- muaj ib tug poob saum tib cov ntshav-siab txog ntsha.

Ib tug los yog ntau tshaj pathological cov tsos mob cia tus kws kho mob los tsim ib tug mob. Yog hais tias tsim nyog, tus kws khomob tshwjxeeb yuav coj tus neeg mob mus ntxiv kev soj ntsuam.
