I-Doppler ultrasound, ekwabizwa ngokuba yi-doppler ultrasound okanye umbala we-eco-doppler, luvavanyo olubalulekileyo lokuvavanya ukujikeleza kwemithambo yegazi kunye nokuhamba kwegazi kwilungu elithile okanye kwingingqi yomzimba. Yiyo ke loo nto inokucelwa ngugqirha kwimeko yokurhanelwa okukrokrelayo, ukunciphisa okanye ukuvalwa kwesitya segazi.

Ezinye zeempawu eziphambili zolu vavanyo kukuvavanywa kwe-thrombosis, i-aneurysms okanye i-varicose veins, umzekelo, kwaye iyasetyenziswa ngokubanzi ngexesha lokukhulelwa, ukujonga ukuba ukuphuma kwegazi ukusuka kumama kuye emntwaneni kwenzeka ngokufanelekileyo, okwaziwa njenge-fetal doppler .

Njengoluvavanyo oluqhelekileyo lwe-ultrasound, i-doppler ultrasound yenziwa kusetyenziswa isixhobo esikwaziyo ukukhupha amaza esandi, afikelela kwinyama kwaye abuye njenge-echo, eguqulwa ibe yimifanekiso. I-doppler yongezelelekileyo ekwaziyo ukubona nokujonga ukuhamba kwegazi kwindawo leyo. Fumanisa ngakumbi malunga neentlobo eziphambili ze-ultrasound kwaye xa zibonisiwe.

I-Doppler ultrasonography yenziwa ngugqirha kwiiklinikhi zokucinga okanye esibhedlele, kwaye ifumaneka simahla yi-SUS okanye ifakwe kwizicwangciso zezempilo. Ngokukodwa, olu vavanyo lunokubiza malunga ne-200 ukuya kwi-500 reais, nangona kunjalo, ixabiso liyahluka ngokwendawo eyenzelwe kuyo, indawo egcinwe kuyo okanye ukuba kukho ezongezelelweyo kuvavanyo, ezinje ngetekhnoloji ye-3D, umzekelo.

Yenzelwe ntoni

Ezinye zeemeko eziphambili apho kuboniswe umbala we-doppler ultrasound zezi:

• Funda ngokusebenza kwegazi kwimithambo kunye nemithambo;
• Khangela i-thrombosis ye-venous okanye ye-arterial;
• Ukuchonga nokuvavanya imithambo ye-varicose;
• Linganisa ukuhamba kwegazi ukusuka kumama kuye kwimveku, nge-placenta, ngexesha lokukhulelwa;
• Chonga ii-aneurysms okanye i-dilations kwimithambo yegazi;
• Chonga ukunciphisa okanye ukuvela kwimithambo kunye nemithambo.

Amaza esandi aveliswe ngexesha lovavanyo avelisa umfanekiso ngqo kwikhompyuter yesixhobo, ukuze ugqirha abone ukuba kukho utshintsho na.

Khathalela uviwo

Uvavanyo lwe-doppler ultrasound lulula kwaye alunantlungu, lufuna ukulala kuphela kwi-stretcher ngelixa ugqirha esenza uviwo. Ukuzila ukutya akuhlali kuyimfuneko, ngaphandle kweemviwo ezenziwa kwingingqi yesisu, njenge-aortic doppler okanye i-artery artery.

Kwezi meko, ukukhawuleza iiyure ezili-10 kunye nokusetyenziswa kwamayeza egesi, ezinje nge-dimethicone, kunokuboniswa ukunciphisa ukwenziwa kweegesi ezinokuphazamisa uviwo.

Iindidi eziphambili

Umbala we-doppler ultrasound unokuyalelwa ukuba uvavanye phantse yonke imimandla yomzimba. Nangona kunjalo, ezinye zezona zicelo ziphambili zikagqirha zezi:

1. I-Doppler ultrasound yemilenze

Ebizwa ngokuba yi-doppler yamalungu asezantsi, ihlala icelwa ukuba ichonge imithambo ye-varicose, thrombosis, ukunciphisa imithambo yegazi, ukuvavanya ukujikeleza kwegazi ngaphambi kotyando kulo mmandla okanye ukuvavanya ubukho beempawu zokungoneliseki kwemithambo-luvo okanye ukungasebenzi kakuhle komzimba, okwabizwa ngokuba kukujikeleza okungalunganga. .

Qonda ukuba yintoni enokubangela ukusasazeka okungalunganga kunye neempawu eziphambili.

2. I-ultrasound yokubeleka kunye neDoppler

Ikwabizwa ngokuba yi-Doppler engekazalwa, iboniswa yingcali yokubelekisa, kwaye isebenza ukuvavanya imithambo yegazi kunye nesantya sokuhamba kwegazi elivela kumbambo wesibeleko nakwi-placenta, kuqatshelwa ukuba ngaba lukhona utshintsho ekuhambeni kwegazi ukuya kwimveku, ukuze kulunge iindlela okanye ixesha lokuhanjiswa.

Olu vavanyo luhlala lwenziwa kwikota yesithathu yokukhulelwa, phakathi kweeveki ezingama-32 ukuya kwezingama-36, kwaye kubaluleke kakhulu ukuba ugqirha ukrokrela utshintsho olwenziwe zizinto ezinje ngokukhula kancinci, isifo seswekile, ukutshintsha kwenani le-amniotic fluid, ukumitha amawele okanye ukuncipha kokuhamba kombungu, umzekelo.

3. I-thyroid Doppler ultrasound

Idyspopler yegilo inokuboniswa ngugqirha endocrinologist ukuvavanya iimpawu zemithambo yegazi yegazi, ukunceda inkqubo yokugqobhoza. Kukwaluncedo ekuchongeni iimpawu ezinobungozi zesinqumka, kuba ubukho bemithambo yegazi engaphezulu kunokuba yenye into ebonisa ukukrokra.

Fumana ngakumbi malunga nokuba i-nodule ye-thyroid ingaba ngumhlaza.

4. ICarotid Doppler Ultrasound

IiCarotids ziimithambo ezihambisa igazi zisuka entliziyweni ziye kwingqondo, kwaye xa zifumana naluphi na utshintsho, njengokuphazamiseka okanye ukunciphisa, zinokubangela iimpawu ezinje ngokuba nesiyezi, ukutyhafa okanye ukubangela ukubetha.

Ke ngoko, i-carotid doppler iboniswa ngugqirha xa olu tshintsho lurhanelwa, ukuvavanya umngcipheko wokubetha kunye nakubantu abaye bahlaselwa sistroke, ukunceda ekuchongeni unobangela. Funda ngakumbi ukuba yeyiphi i-carotid ultrasound.

5. I-Doppler ultrasound yemithambo yegazi

Ihlala iboniswa ngugqirha wezifo zengqondo ukuba aphonononge ukuhamba kwemithambo yezintso, efuna ukubona ukubambeka kunye nokuvalwa kwezi nqanawa, ezingunobangela woxinzelelo lwegazi olunzima ukulawula.

Banokuboniswa ukuba bajonge oonobangela bokutshintsha kwezintso, njengokunciphisa ubungakanani, ii-aneurysms okanye iziphene ezikrokrelwayo.

6. I-Doppler ultrasound ye-aorta

Kuyaboniswa ukuvavanya ubukho bokuthamba okanye i-aneurysm kwi-aorta, enokuthi ikrokrele abantu abanesimbombo esiswini. Kukwaluncedo ukuphanda ukusikwa kwempahla kule nqanawa, ingxaki enzulu ebangelwe kukungqinelana kweendonga zayo, okanye nokujonga ubukho bamatye e-atherosclerosis anokubangela isithintelo se-aorta.

Olu vavanyo lukwabaluleke kakhulu ukucwangcisa utyando lokulungisa, ukuba kubonisiwe ngugqirha. Jonga indlela yokuchonga i-aortic aneurysm kunye nendlela yokuyinyanga.
