Iyini iDoppler ultrasound?

I-Doppler ultrasound isivivinyo sokuthatha izithombe esisebenzisa amagagasi omsindo ukukhombisa ukuhamba kwegazi emithanjeni yegazi. I-ultrasound ejwayelekile futhi isebenzisa amagagasi omsindo ukudala izithombe zezakhiwo ngaphakathi komzimba, kodwa ayikwazi ukukhombisa ukugeleza kwegazi.

I-Doppler ultrasound isebenza ngokulinganisa amaza omsindo abonakala ezintweni ezihambayo, njengamaseli abomvu egazi. Lokhu kwaziwa njengomphumela weDoppler.

Kunezinhlobo ezahlukahlukene zokuhlolwa kwe-Doppler ultrasound. Kubandakanya:

• Umbala Doppler. Lolu hlobo lweDoppler lusebenzisa ikhompyutha ukushintsha amaza omsindo abe yimibala ehlukene. Le mibala ikhombisa ukushesha nokuqondisa kokugeleza kwegazi ngesikhathi sangempela.
• I-Power Doppler, uhlobo olusha lombala iDoppler. Inganikeza imininingwane eminingi yokuhamba kwegazi kuneDoppler yombala ojwayelekile. Kepha ayikwazi ukukhombisa ukuhanjiswa kwegazi, okungabaluleka kwezinye izimo.
• I-Spectral Doppler. Lokhu kuhlolwa kukhombisa imininingwane yokuhamba kwegazi kwigrafu, kunezithombe zombala. Kungasiza ukukhombisa ukuthi kungakanani isitsha segazi esivinjiwe.
• Duplex Doppler. Lokhu kuhlolwa kusebenzisa i-ultrasound ejwayelekile ukuthatha izithombe zemithambo yegazi nezitho zomzimba. Ngemuva kwalokho ikhompyutha iguqula izithombe zibe igrafu, njengakwi-spectral Doppler.
• Okuqhubekayo igagasi Doppler. Kulesi sivivinyo, amagagasi omsindo athunyelwa futhi atholwe ngokuqhubekayo. Ivumela ukukalwa okunembe kakhudlwana kwegazi eligeleza ngejubane elisheshayo.

Amanye amagama: Doppler ultrasonography

Kusetshenziselwa ini?

Ukuhlolwa kwe-Doppler ultrasound kusetshenziselwa ukusiza abahlinzeki bezokunakekelwa kwezempilo ukuthi bathole ukuthi ngabe unesimo esinciphisa noma esivimba ukugeleza kwegazi lakho. Ingasetshenziselwa ukusiza ukuxilonga izifo ezithile zenhliziyo. Isivivinyo sivame ukusetshenziselwa:

• Hlola ukusebenza kwenhliziyo. Kuvame ukwenziwa kanye ne-electrocardiogram, isivivinyo esilinganisa izimpawu zikagesi enhliziyweni.
• Bheka ukuvinjelwa kokugeleza kwegazi. Ukuhamba kwegazi okuvinjiwe emilenzeni kungadala isimo esibizwa nge-deep vein thrombosis (DVT).
• Bheka ukulimala komthambo wegazi kanye nokukhubazeka ekwakhekeni kwenhliziyo.
• Bheka ukunciphisa imithambo yegazi. Imithambo emincane ezingalweni nasemilenzeni kungasho ukuthi unesimo esibizwa ngokuthi yi-peripheral arterial disease (PAD). Ukuncipha kwemithambo entanyeni kungasho ukuthi unesimo esibizwa nge-carotid artery stenosis.
• Bheka ukugeleza kwegazi ngemuva kokuhlinzwa.
• Bheka ukugeleza kwegazi okujwayelekile kowesifazane okhulelwe nasenganeni yakhe engakazalwa.

Kungani ngidinga i-Doppler ultrasound?

Ungadinga i-Doppler ultrasound uma unezimpawu zokwehla kwegazi noma isifo senhliziyo. Izimpawu ziyahlukahluka kuye ngesimo esidala inkinga. Ezinye izimo zokugeleza kwegazi kanye nezimpawu zingezansi.

Izimpawu zesifo se-peripheral arterial disease (PAD) zifaka:

• Ukuba ndikindiki noma ubuthakathaka emilenzeni yakho
• Ukuqunjelwa kabuhlungu ezinqeni noma emisipheni yemilenze lapho uhamba noma ukhuphuka izitebhisi
• Umuzwa obandayo emlenzeni wakho wezinyawo noma onyaweni
• Shintsha umbala kanye / noma isikhumba esikhanyayo emlenzeni wakho

Izimpawu zezinkinga zenhliziyo zifaka:

• Ukuphelelwa umoya
• Ukuvuvukala emilenzeni, ezinyaweni, kanye / noma esiswini
• Ukukhathala

Ungadinga futhi iDoppler ultrasound uma:

• Ngibe nesifo sohlangothi. Ngemuva kokushaywa unhlangothi, umhlinzeki wakho wezokunakekelwa kwempilo anga-oda uhlobo olukhethekile lokuhlolwa kukaDoppler, olubizwa nge-transcranial Doppler, ukuhlola ukugeleza kwegazi kuya ebuchosheni.
• Ngaba nokulimala emithanjeni yakho yegazi.
• Belashwa ukwelashwa kokugeleza kwegazi.
• Ukhulelwe kanti umhlinzeki wakho ucabanga ukuthi wena noma ingane yakho engakazalwa ingaba nenkinga yokugeleza kwegazi. Umhlinzeki wakho angasola inkinga uma ingane yakho engakazalwa incane kunalokho okufanele ibe kulesi sigaba sokukhulelwa noma uma unezinkinga ezithile zempilo. Lokhu kubandakanya isifo se-sickle cell noma i-preeclampsia, uhlobo lomfutho wegazi ophezulu othinta abesifazane abakhulelwe.

Kwenzekani ngesikhathi se-Doppler ultrasound?

I-Doppler ultrasound ivame ukufaka lezi zinyathelo ezilandelayo:

• Uzolala itafula, uveze indawo yomzimba wakho ehlolwayo.
• Umhlinzeki wezokunakekelwa kwempilo uzokwendlala ijeli esikhumbeni kuleyo ndawo.
• Umhlinzeki uzohambisa into efana ne-wand, ebizwa ngokuthi i-transducer, phezu kwendawo.
• Umshini uthumela amaza omsindo emzimbeni wakho.
• Ukuhamba kwamaseli egazi kudala ushintsho ekuphakameni kwamagagasi omsindo. Ungase uzwe ukushwibeka noma ukushaya kwemisindo efana nenqubo ngesikhathi senqubo.
• Amagagasi ayarekhodwa aguqulwe abe yimifanekiso noma amagrafu kusiqaphi.
• Ngemuva kokuhlolwa, umhlinzeki uzosula ijeli emzimbeni wakho.
• Ukuhlolwa kuthatha imizuzu engama-30-60 ukuqeda.

Ngabe kukhona engizodinga ukukwenza ukulungiselela isivivinyo?

Ukulungiselela iDoppler ultrasound, kungadingeka ukuthi:

• Susa okokugqoka nobucwebe endaweni yomzimba eyohlolwa.
• Gwema osikilidi neminye imikhiqizo ene-nicotine kuze kufike emahoreni amabili ngaphambi kokuhlolwa kwakho. I-nicotine ibangela ukuthi imithambo yegazi inciphe, okungathinta imiphumela yakho.
• Ngezinhlobo ezithile zokuhlolwa kwe-Doppler, ungacelwa ukuthi uzile (ungadli noma uphuze) amahora ambalwa ngaphambi kokuhlolwa.

Umhlinzeki wakho wezokunakekelwa kwempilo uzokwazisa uma ngabe udinga ukwenza noma yini ukulungiselela ukuhlolwa kwakho.

Ingabe zikhona izingozi esivivinyweni?

Azikho izingozi ezaziwayo zokuba ne-Doppler ultrasound. Kubhekwa nokuthi kuphephile ngesikhathi sokukhulelwa.

Isho ukuthini imiphumela?

Uma imiphumela yakho ibingejwayelekile, kungasho ukuthi une:

• Ukuvaleka noma ukubambeka emthanjeni
• Imithambo yegazi eminyene
• Ukugeleza kwegazi okungavamile
• I-aneurysm, ibhaluni elifana nebhaluni emithanjeni yegazi. Kubangela ukuthi imithambo yegazi ivuleke futhi ibe mncane. Uma udonga luba mncane kakhulu, umthambo ungaqhuma, ubangele ukopha okusongela impilo.

Imiphumela ingakhombisa nokuthi ngabe kukhona ukugeleza kwegazi okungavamile enganeni engakazalwa.

Incazelo yemiphumela yakho izoncika ekutheni iyiphi indawo yomzimba ebihlolwa. Uma unemibuzo ngemiphumela yakho, khuluma nomhlinzeki wakho wezokunakekelwa kwempilo.
