I-Doppler ultrasound, ebizwa nangokuthi i-doppler ultrasound noma i-color eco-doppler, isivivinyo esibalulekile sokuhlola ukujikeleza kwemithambo yegazi nokugeleza kwegazi esithweni esithile noma esifundeni somzimba. Ngakho-ke, kungacelwa udokotela ezimweni zokuncipha okusolwayo, ukuvuleka noma ukuvalwa kwesitsha segazi.

Ezinye zezinkomba eziyinhloko zalesi sivivinyo ukuhlolwa kwe-thrombosis, i-aneurysms noma i-varicose veins, ngokwesibonelo, futhi isetshenziswa kabanzi ngesikhathi sokukhulelwa, ukuhlola ukuthi ukugeleza kwegazi kusuka kumama kuya embungwini kwenzeka kahle, okwaziwa njenge-fetal doppler .

Njengokuhlolwa okuvamile kwe-ultrasound, i-doppler ultrasound yenziwa kusetshenziswa idivaysi ekwazi ukukhipha amagagasi omsindo, afinyelela izicubu bese ebuya njenge-echo, eguqulwa ibe yimifanekiso. I-doppler iyona eyengeziwe ekwazi ukukhomba nokubona ngeso lengqondo ukugeleza kwegazi kusayithi. Thola okuningi mayelana nezinhlobo eziyinhloko ze-ultrasound nokuthi zikhonjiswa nini.

I-Doppler ultrasonography yenziwa ngudokotela emitholampilo yezithombe noma esibhedlela, futhi itholakala mahhala yi-SUS noma ifakwe ezinhlelweni zezempilo. Ikakhulu, lokhu kuhlolwa kungabiza cishe ama-200 kuya kuma-500 reais, noma kunjalo, intengo iyahlukahluka ngokwendawo okwenziwa kuyo, indawo ebonwayo noma uma kukhona okungeziwe esivivinyweni, njengobuchwepheshe be-3D, isibonelo.

Yenzelwe ini

Ezinye zezimo eziyinhloko lapho kuboniswa khona umbala we-doppler ultrasound yizi:

• Fundisisa ukusebenza kokugeleza kwegazi kwemithambo nemithambo;
• Thola i-venous or arterial thrombosis;
• Xilonga futhi uhlole imithambo ye-varicose;
• Linganisa ukuhamba kwegazi kusuka kumama kuya embungwini, nge-placenta, ngesikhathi sokukhulelwa;
• Khomba ama-aneurysms noma ukuvuleka emithanjeni yegazi;
• Khomba ukuncipha noma ukuvaleka emithanjeni nasemithanjeni yegazi.

Amagagasi omsindo akhiqizwa ngesikhathi sokuhlolwa akhiqiza isithombe ngqo esikrinini sekhompyutha sedivayisi, ukuze udokotela abone ukuthi kukhona yini ushintsho.

Nakekela ukuhlolwa

Ukuhlolwa kwe-doppler ultrasound kulula futhi akunabuhlungu, okudinga ukulala kuphela ku-stretcher ngenkathi udokotela enza ukuhlolwa. Ukuzila ukudla akuvamile kudingekile, ngaphandle kwezivivinyo ezenziwa esifundeni sesisu, njenge-aortic doppler noma imithambo ye-renal.

Kulezi zimo, ukushesha kwamahora ayi-10 nokusetshenziswa kwemithi yamagesi, njenge-dimethicone, kungakhonjiswa ukunciphisa ukwakheka kwamagesi angaphazamisa ukuhlolwa.

Izinhlobo eziyinhloko

Umbala we-doppler ultrasound unga-oda ukuthi uhlole cishe zonke izifunda zomzimba. Kodwa-ke, ezinye zezicelo eziphambili zikadokotela yilezi:

1. I-Doppler ultrasound yemilenze

Ebizwa ngokuthi yi-doppler yezitho ezingezansi, kuvame ukucelwa ukuthi kutholakale imithambo ye-varicose, thrombosis, ukunciphisa imithambo yegazi, ukuhlola ukujikeleza kwegazi ngaphambi kokuhlinzwa esifundeni noma ngisho nokuhlola ubukhona bezimpawu zokungakwazi ukusebenza kahle kwemithambo yegazi noma kwemithambo yegazi, okubizwa nangokuthi ukusakazwa kahle komzimba .

Qonda ukuthi yini engadala ukusakazeka okungalungile nezimpawu eziyinhloko.

2. I-ultrasound yokubeletha eneDoppler

Eyaziwa nangokuthi i-fetal Doppler, ikhonjiswa ngudokotela obelethisa, futhi isebenza ukuhlola imithambo yegazi nokushesha kokugeleza kwegazi kusuka enkabeni nasempondweni, kubhekwe ukuthi ngabe kukhona yini ushintsho ekugelezeni kwegazi kuya embungwini, ukuze kusebenze kangcono izindlela noma isikhathi sokulethwa.

Lokhu kuhlolwa kuvamise ukwenziwa esikhathini sesithathu sokukhulelwa, phakathi kwamasonto angama-32 kuya kwangama-36, futhi kuyadingeka ikakhulukazi uma udokotela esola ushintsho olubangelwa yizimo ezinjengokungakhuli kahle, isifo sikashukela sikamama, izinguquko kwinani le-amniotic fluid, ukumitha amawele noma ukuncipha kokuhamba kombungu, isibonelo.

3. I-ultrasound ye-Thyroid Doppler

I-doppler yegilo ingakhonjiswa ngudokotela we-endocrinologist ukuhlola izici zemithambo yegazi yegilo, ukusiza uhlelo lokugcotshwa. Kuyasiza futhi ukukhomba izici eziyingozi ze-nodule, ngoba ukutholakala kwemithambo yegazi eyeqile kungaba esinye isibonakaliso se-nodule esolisayo.

Thola kabanzi mayelana nokuthi i-nodule yegilo ingaba yini umdlavuza.

4. I-Carotid Doppler Ultrasound

AmaCarotids yimithambo ehambisa igazi lisuka enhliziyweni liyise ebuchosheni, futhi lapho ihlangabezana nanoma yiziphi izinguquko, njengokuvinjelwa noma ukuncipha, zingadala izimpawu ezinjengokuzondwa ikhanda, ukuquleka noma kubangele nesifo sohlangothi.

Ngakho-ke, i-carotid doppler ikhonjiswa ngudokotela lapho kusolwa lezi zinguquko, ukuhlola ubungozi bokushaywa unhlangothi kanye nakubantu abahlushwe unhlangothi, ukusiza ukuthola imbangela. Funda kabanzi kulokho okushiwo yi-carotid ultrasound.

5. I-Doppler ultrasound yemithambo yezinso

Imvamisa kukhonjiswa yi-nephrologist ukutadisha ukuhamba kwemithambo yezinso, ifuna ukukhomba ukuncipha kanye nokuqhekeka kwale mikhumbi, okuyizimbangela zomfutho wegazi ophezulu okunzima ukuwulawula.

Zingakhonjiswa futhi ukuthi zibheke izimbangela zokushintshwa kwezinso, njengokuncipha kosayizi, ama-aneurysms okusolwa ngawo noma ukukhubazeka.

6. I-Doppler ultrasound ye-aorta

Kuboniswa ukuhlola ukutholakala kokuhlanza noma i-aneurysm ku-aorta, okungasolisa kubantu abanokukhononda kwesisu. Kuyasiza futhi ukuphenya ukuhlukaniswa kwemikhumbi kulo mkhumbi, okuyinkinga enkulu ebangelwa ukuhlukaniswa kwezindonga zawo, noma ngisho nokubona ukutholakala kwamapulangwe e-atherosclerosis angadala ukuvinjelwa kwe-aorta.

Lokhu kuhlolwa futhi kubaluleke kakhulu ukuhlela ukuhlinzwa kokulungisa, uma kukhonjiswa ngudokotela. Bheka ukuthi ungayibona kanjani i-aortic aneurysm nokuthi ungayelapha kanjani.
